Annotation of ircnowd/ChangeLog, Revision 1.1.1.1

1.1       tomglok     1:
                      2:                      ngIRCd - Next Generation IRC Server
                      3:                            http://ngircd.barton.de/
                      4:
                      5:                (c)2001-2021 Alexander Barton and Contributors.
                      6:                ngIRCd is free software and published under the
                      7:                    terms of the GNU General Public License.

                     10:
                     11: ngIRCd 26.1 (2021-01-02)
                     12:
                     13:   - Fix a "format string" compiler warning (detected on OpenBSD).
                     14:   - No longer set "AI_ADDRCONFIG" when resolving host names, even when it
                     15:     exists: with this option set, on an IPv6-only host, we prevent 127.0.0.1
                     16:     to get translated properly, even when the loopback interface has this
                     17:     address configured! And as the test suite uses 127.0.0.1, it was broken
                     18:     on IPv6-only hosts.
                     19:     The drawback is that the resolver possibly returns more addresses now,
                     20:     even of an unsupported/not connected address family; but this shouldn't
                     21:     do much harm in practice, as ngIRCd iterates over all returned addresses
                     22:     while trying to establish an outgoing connection.
                     23:     Closes #281.
                     24:   - Revert "Show allowed channel types in ISUPPORT(005) numeric only", which
                     25:     was introduced in 26~rc1: This lead to some IRC clients assuming "oh, no
                     26:     channel prefix characters at all, so no channels at all, so no PRIVMSG can
                     27:     go to any channel" when "AllowedChannelTypes" was set to the empty string
                     28:     ("") -- which is not the case when there are pre-defined channel set up or
                     29:     other servers still having channels!
                     30:     So "allowed channel types" != "supported channel types", and we always have
                     31:     to list all supported ones in the ISUPPORT(005) numeric!
                     32:     Closes #285.
                     33:   - Test suite: Wait 2 seconds after reloading the daemon, which is required
                     34:     because on reload, all listening ports are closed, configuration updated,
                     35:     and then opened again. This lead to subsequent tests running while the
                     36:     daemon isn't listening on any ports, and that's why some tests could fail.
                     37:     Closes #280.
                     38:   - platformtest.sh: Try to mangle CLang name more intelligently.
                     39:   - Documentation: Fixed URLs of Atheme IRC services, updated all mentions
                     40:     from CVS to Git, and updated Platforms.txt -- Oh, and it is 2021 now! ;-)
                     41:
                     42: ngIRCd 26 (2020-06-20)
                     43:
                     44:   ngIRCd 26~rc2 (2020-06-11)
                     45:   - Add AppStream metadata file (contrib/de.barton.ngircd.metainfo.xml).
                     46:   - Don't send invalid CHANINFO commands when a channel has mode +k set but no
                     47:     key is known to the server. This can happen with a misconfigured predefined
                     48:     channel, for example, and looked like this: "CHANINFO #test +Pk  0 :" --
                     49:     note the unset key represented by the two spaces. Fix this by sending a
                     50:     "*" in this case and update the CHANINFO documentation, too.
                     51:   - ngircd.spec: Fix names of README.md and INSTALL.md, add ".md" extension.
                     52:   - Update description texts in the README.md file, the RPM and Debian package
                     53:     files and the manual page: bring them in line with the updated homepage.
                     54:   - Server-Server protocol: Fix use-after-free when unregistering a directly
                     55:     connected server sending a SQUIT for itself.
                     56:   - Server-Server protocol: Detect bogus SERVER commands lacking a prefix.
                     57:     Thanks Hilko Bengen (hillu) for finding & reporting this as well for the
                     58:     patch & pull request (even if fixed differently).
                     59:     Closes #275.
                     60:   - Fix the PING-PONG logic: In ngIRCd 26~rc1 this was completely broken (while
                     61:     trying to fix timeouts during server handshakes in bigger networks): the
                     62:     daemon never disconnected any stale peers but kept sending out PINGs over
                     63:     and over again ...
                     64:   - Test suite: Add missing files needed to test SSL support to "EXTRA_DIST",
                     65:     so that they are included in distribution archives: in rc1, "make check"
                     66:     fails when using sources from an archive and enabling SSL support.
                     67:     Thanks to Hilko Bengen <bengen@hilluzination.de> for the patch!
                     68:
                     69:   ngIRCd 26~rc1 (2020-05-10)
                     70:   - Tweak & update doc/HowToRelease.txt, .mailmap and AUTHORS files.
                     71:   - Allow up to 512 characters per line in MOTD and help text files (but keep
                     72:     in mind that lines can't get that long, because they have to be prefixed
                     73:     before being sent to the client). But this allows for more fancy MOTDs :-)
                     74:     Closes #271.
                     75:   - Show the actually allowed channel types in the ISUPPORT(005) numeric which
                     76:     are configured by the "AllowedChannelTypes" configuration variable.
                     77:     Closes #273.
                     78:   - Handle commands in the read buffer before reading more data and don't wait
                     79:     for the network in this case: If there are more bytes in the read buffer
                     80:     already than a single valid IRC command can get long (513 bytes), wait for
                     81:     this/those command(s) to be handled first and don't try to read even more
                     82:     data from the network (which most probably would overflow the read buffer
                     83:     of this connection soon).
                     84:   - Update Travis-CI configuration, "sudo" is deprecated.
                     85:   - Log G-/K-Line changes only when not initiated by a server: this prevents
                     86:     the log from becoming spammed during "net bursts".
                     87:   - Update test suite to include SSL tests, including checking for reloading
                     88:     certificates during runtime.
                     89:   - Makefile.am: Replace "make" with "${MAKE}". This fixes warnings like this:
                     90:     "warning: jobserver unavailable: using -j1. Add `+' to parent make rule."
                     91:     Thanks to Sam James (sam_c) <sam@cmpct.info>!
                     92:     Closes #270.
                     93:   - Add support for GnuTLS certificate reload, which is quite handy when using
                     94:     Let's Encrypt, for example. Until now this was only supported when linked
                     95:     with OpenSSL. Thanks a lot, Hilko Bengen <bengen@hilluzination.de>!
                     96:   - Remove deprecated legacy configuration options and related functions that
                     97:     have been marked for removal for quite some time:
                     98:     - PredefChannelsOnly (v22)
                     99:     - NoticeAuth (v24)
                    100:     - NoXXX (v19)
                    101:     - Old '[GLOBAL]' section handling (v19)
                    102:     Thanks to Michi <michi+ngircd@dataswamp.org> for the patch!
                    103:   - Fix recursion bug on write errors: Depending on the stack size, too many
                    104:     clients on the same channel quitting at the same time would trigger a crash
                    105:     due to too many recursive calls to Conn_Close(). Thanks to Michi
                    106:     <michi+ngircd@dataswamp.org> for the patch!
                    107:   - Fix builds using GCC option -fno-common, which is the default starting with
                    108:     GCC 10. Thanks to Michi <michi+ngircd@dataswamp.org> for the patch!
                    109:     Closes #266.
                    110:   - Convert INSTALL and README files to Markdown.
                    111:   - Allow setting arbitrary channel modes in the configuration file by handling
                    112:     them like in MODE commands, and allow multiple "Modes =" lines per [Channel]
                    113:     section. Thanks to Michi <michi+ngircd@dataswamp.org>!
                    114:     Closes #55.
                    115:   - Add "FNC" (forced nick changes) to ISUPPORT(005) numeric. Most probably
                    116:     this doesn't make any difference to any client, but it seems correct.
                    117:     See <http://www.irc.org/tech_docs/005.html> for details.
                    118:   - Reuse old SSL key if loading a new one failed.
                    119:   - Remove outdated OpenBSD/NetBSD systrace.policy.
                    120:   - Enhance handling of command line errors, and return with exit code 0 ("no
                    121:     error") when "--help" or "--version" is used (which resulted in exit code 1,
                    122:     "error" before). Exit with code 2 ("command line error") for all other
                    123:     invalid command line options, and show the error message itself on stderr
                    124:     (instead of stdout and exit code 1, "generic error", as before).
                    125:     This new behaviour is more in line with the GNU "coding standards",
                    126:     see <https://www.gnu.org/prep/standards/html_node/_002d_002dhelp.html>.
                    127:   - Fix and update Xcode project: Reference correct contrib/Makefile.am file,
                    128:     correctly sort contrib/nglog.sh and add "ORGANIZATIONNAME" setting.
                    129:   - contrib/ngindent.sh: Add more GNU indent options for better results, and
                    130:     add the ".sh" suffix to bring this script in line with the others in the
                    131:     contrib/ folder.
                    132:   - Add ./contrib/nglog.sh: This script parses the log output of ngircd(8),
                    133:     and colorizes the messages according to their log level. Example usage:
                    134:     ngircd -f $PWD/doc/sample-ngircd.conf -np | ./contrib/nglog.sh
                    135:   - Log received signals with their names using strsignal(3), when available.
                    136:   - Make test suite compatible with Haiku OS.
                    137:   - Fix host mask cloaking bug, don't cloak multiple times: Previously, each
                    138:     server would cloak every user's host mask. The problem is that if a network
                    139:     has more than one server, then a user's host mask would get cloaked twice.
                    140:     This patch ensures that a server only cloaks the host mask if it has not yet
                    141:     been cloaked (the period indicates it's still an IP address). Thanks to
                    142:     JRMU <jrmu@lecturify.com> for the patch!
                    143:     Closes #228.
                    144:   - Enlarge buffers of info texts to 128 bytes. This includes:
                    145:     - "Real name" of a client (4th filed of the USER command).
                    146:     - Server info text ("Info" configuration option).
                    147:     - Admin info texts and email address ("AdminInfo1", "AdminInfo2" and
                    148:       "AdminEmail" configuration options).
                    149:     - Network name ("Network" configuration option).
                    150:     The limit was 64 bytes before ...
                    151:     Closes #258.
                    152:   - Streamline handling of invalid and unset server name: Don't exit during
                    153:     runtime (REHASH command, HUP signal), because the server name can't be
                    154:     changed in this case anyway and the new invalid name will be ignored.
                    155:   - Fix and extend documentation: Fix some typos, fix syntax of LINKS and LIST
                    156:     commands, whitespace and spelling fixes, update dependencies and add some
                    157:     more information about IRCv3 support.
                    158:     Thanks to Thanks Windree, Étienne Mollier <etienne.mollier@mailoo.org> and
                    159:     Christoph Biedl <debian.axhn@manchmal.in-ulm.de>.
                    160:     Closes #264.
                    161:   - Slightly reorder startup steps, and enhance logging:
                    162:     - Show name of configuration file at the beginning of start up.
                    163:     - Add a message when ngIRCd is ready, including its host name.
                    164:     - Show name of configuration file on REHASH (SIGHUP), too.
                    165:     - Change level of "done message" to NOTICE, like "starting" & "ready".
                    166:     - Initialize IO functions before channels, connections, clients, ...
                    167:   - configure.ng: OpenSSL can depends on lz or latomic so use pkg-config to
                    168:     find those dependencies and fallback to existing mechanism.
                    169:     Closes #256.
                    170:   - ngircd.conf.5: Fix wording as suggested by lintian.
                    171:
                    172: ngIRCd 25 (2019-01-23)
                    173:
                    174:   - Fix documentation of MotdPhrase length, which actually is 126 characters:
                    175:     update sample configuration file as well as the man page. Thanks to
                    176:     shankari <shankari@eecs.berkeley.edu>.
                    177:     Closes #254.
                    178:   - Implement new configuration option "MaxPenaltyTime", which configures the
                    179:     maximum penalty time increase in seconds, per penalty event. Set to -1 for
                    180:     no limit (the default), 0 to disable penalties altogether. ngIRCd doesn't
                    181:     use penalty increases higher than 2 seconds during normal operation, so
                    182:     values higher than 1 rarely make sense.
                    183:     Disabling (or reducing) penalties can greatly speed up "make check" runs
                    184:     for example, see below, but are mostly a debugging feature and normally
                    185:     not meant to be used on production systems!
                    186:     Some example timings running "make check" from my macOS workstation:
                    187:      - MaxPenaltyTime not set: 4:41,79s
                    188:      - "MaxPenaltyTime = 1":   3:14,71s
                    189:      - "MaxPenaltyTime = 0":     25,46s
                    190:     Closes #249 and #251.
                    191:   - Fix compilation without deprecated OpenSSL APIs. Thanks to Rosen Penev
                    192:     <rosenp@gmail.com> for the patch!
                    193:     Closes #252.
                    194:   - Update Xcode project for latest Xcode version (10.0)
                    195:   - Fix some compiler warnings of Apple Xcode/Clang
                    196:   - Allow a 5th parameter in WEBIRC. Thanks to "ItsOnlyBinary".
                    197:     Closes #247.
                    198:   - Update some more documentation files and source code comments.
                    199:   - Platforms.txt: Add and update systems.
                    200:
                    201:   ngIRCd 25~rc1 (2018-08-11)
                    202:   - Update config.guess (2018-03-08) and config.sub (2018-03-08) files.
                    203:   - Correctly retry to establish an outgoing connections when forking of the
                    204:     resolver sub-process failed (for example because of lack of free memory).
                    205:     Until now, such a connection was never retried once this error was hit.
                    206:     Thanks to Robert Obermeier for reporting this bug!
                    207:     Closes #243.
                    208:   - Fix a "use after free" bug which can be triggered on a newly established
                    209:     connection when the daemon handles an ERROR command received from the peer
                    210:     during client login. Thanks a lot to Joseph Bisch <joseph.bisch@gmail.com>
                    211:     for discovering and reporting this issue!
                    212:   - Only send TOPIC updates to a channel when the topic actually changed:
                    213:     This prevents the channel from becoming flooded by unnecessary TOPIC update
                    214:     messages, that can happen when IRC services try to enforce a certain topic
                    215:     but which is already set (at least on the local server), for example.
                    216:     Therefore still forward it to all servers, but don't inform local clients
                    217:     (still update setter and timestamp information, though).
                    218:   - Update Xcode project for latest Xcode version (9.2). This includes adding
                    219:     missing and deleting obsolete file references.
                    220:   - Handle user mode "C" ("Only users that share a channel are allowed to send
                    221:     messages") like user mode "b" ("block private messages and notices"): allow
                    222:     messages from servers, services, and IRC Operators, too. Change proposed by
                    223:     "wowaname" back in 2015 in #ngircd, thanks!
                    224:   - Fix some compiler warnings.
                    225:   - Add contrib/ngircd.logcheck: Some sample logcheck(8) rules.
                    226:   - Allow IRC Ops and remote servers to KILL service clients: such clients
                    227:     behave like regular users, therefore IRC operators and servers should be
                    228:     able to KILL them: for example to resolve nick collisions.
                    229:     Closes #242.
                    230:   - Don't forward KILLs to other servers if they've been blocked locally:
                    231:     This prevents clients from killing IRC services, for example.
                    232:     Closes #238 and #239.
                    233:   - Fix a cross-compiler issue related to the Get_Error() function.
                    234:     Closes #240 and #241.
                    235:   - Update ./doc/Services.txt, enhance configuration examples.
                    236:
                    237: ngIRCd 24 (2017-01-20)
                    238:
                    239:   - Make sure that ./contrib/platformtest.sh aborts when ./autogen.sh fails.
                    240:   - Update config.guess (2016-10-02) and config.sub (2016-11-04) files.
                    241:   - Build Debian packages with OpenSSL instead of GnuTLS: OpenSSL allows
                    242:     to reload used certificates on runtime for example (which is very
                    243:     useful when using Let's Encrypt), and therefore is preferred. And
                    244:     explicitly specify the "source format".
                    245:   - Fix handling of connection pool allocation and enlargement: up to now,
                    246:     the daemon only enlarged its connection pool when accepting new incoming
                    247:     client or server connections, not when establishing new outgoing server
                    248:     links, which could lead to problems when hitting the configured limit,
                    249:     see "MaxConnections". Thanks to Lukas Braun (k00mi) for reporting this!
                    250:     Closes #231.
                    251:
                    252:   ngIRCd 24~rc1 (2017-01-07)
                    253:   - Enhance systemd service file, and install it in Debian package.
                    254:   - Update configuration of Debian package.
                    255:   - Log privilege violations and failed OPER request with log level "error"
                    256:     and send it to the "&SERVER" channel, too.
                    257:   - Immediately shut down connection when receiving an "ERROR" command,
                    258:     don't wait for the peer to close the connection. This allows the daemon
                    259:     to forward the received "ERROR" message in the network, instead of the
                    260:     very generic "client closed connection" message.
                    261:   - Fix sending of entry duration (no negative values!) when synchronizing
                    262:     "x-lines" (G-LINES).
                    263:   - List expiration (G-LINES): use same log level as when setting, and log
                    264:     this event to the &SERVER channel, too.
                    265:   - Explicitly forbid remote servers to modify "x-lines" (G-LINES) when the
                    266:     "AllowRemoteOper" configuration option isn't set, even when the command
                    267:     seems to originate from the remote server itself: this prevents GLINE's
                    268:     to become set during server handshake in this case (what wouldn't be
                    269:     possible during regular runtime when a remote IRC Op sends the command)
                    270:     and what can't be undone by IRC Ops later on (because of the missing
                    271:     "AllowRemoteOper" option) ...
                    272:   - Make scripts and init-files in ./contrib executable.
                    273:   - Fix building ngIRCd with OpenSSL 1.1. Thanks to Christoph Biedl
                    274:     <ngircd.anoy@manchmal.in-ulm.de> for the patch!
                    275:   - Fix code indentation warnings of gcc 6.2.
                    276:   - Update config.guess (2016-04-02) and config.sub (2016-03-30) files.
                    277:   - Fix warnings of the "shellcheck" linter in autogen.sh, contrib/ngindent
                    278:     and contrib/platformtest.sh.
                    279:   - Update Xcode project for latest Xcode version (8.0), and fix "duplicate
                    280:     symbols" error messages when building (linking) the binary.
                    281:   - Add "Documentation" variables to systemd configuration files.
                    282:   - Make sure that SYSCONFDIR is always set, which can be handy when
                    283:     using source code linters when ./configure hasn't been run already.
                    284:   - Add the new "PAMServiceName" configuration option to specify the name
                    285:     used as PAM service name. This setting allows to run multiple ngIRCd
                    286:     instances with different PAM configurations for each instance.
                    287:     Thanks to Christian Aistleitner <christian@quelltextlich.at> for the
                    288:     patch, closes #226.
                    289:   - Add an ".editorconfig" file to the project.
                    290:   - Travis-CI: use "container-based infrastructure".
                    291:   - Limit the number of message targets, and suppress duplicates: This
                    292:     prevents an user from flooding the server using commands like this:
                    293:     "PRIVMSG nick1,nick1,nick1,...".
                    294:     Duplicate targets are suppressed silently (channels and clients).
                    295:     In addition, the maximum number of targets per PRIVMSG, NOTICE, ...
                    296:     command are limited to MAX_HNDL_TARGETS (25). If there are more, the
                    297:     daemon sends the new 407 (ERR_TOOMANYTARGETS_MSG) numeric, containing
                    298:     the first target that hasn't been handled any more. Closes #187.
                    299:   - Test suite: Add new test for server-server logins.
                    300:   - contrib/ngindent: Fix shebang line.
                    301:   - Make contrib/platformtest.sh script more portable, and only show
                    302:     "runs=Y" when the test suite really has been passed successfully.
                    303:   - Code cleanup in the NJON handler and the function killing clients as
                    304:     well as the function sending messages to a "mask" (cleaner code, more
                    305:     fault tolerant, better code comments).
                    306:   - Update and enhance documentation: README file, doc/Platforms.txt,
                    307:     doc/Modes.txt, doc/Commands.txt, doc/PAM.txt.
                    308:   - Fix NJOIN not propagating "half ops" status: ngIRCd tested for the wrong
                    309:     prefix of "half ops" when processing NJOIN commands and therefore never
                    310:     classified a remote user as "half op".
                    311:     Thanks to wowaname for pointing this out on #ngircd!
                    312:
                    313: ngIRCd 23 (2015-11-16)
                    314:
                    315:   - Explicitly cast time_t to long when printing it out: this prevents
                    316:     wrong sized data types on platforms where time_t doesn't equal a
                    317:     long any more, for example on OpenBSD (which would result in garbled
                    318:     output on those platforms).
                    319:   - contrib/Debian/changelog: Fix email address.
                    320:   - Documentation: Spelling fixes; update doc/Platforms.txt.
                    321:
                    322:   ngIRCd 23~rc1 (2015-09-06)
                    323:   - Add ".clang_complete" file, which is used by the "linter-clang" package
                    324:     of the Atom editor, for example.
                    325:   - Make server-to-server protocol more robust: ngIRCd now catches more
                    326:     errors on the server-to-server (S2S) protocol that could crash the
                    327:     daemon before. This hasn't been a real problem because the IRC S2S
                    328:     protocol is "trusted" by design, but the behavior is much better now.
                    329:     Thanks to wowaname on #ngircd for pointing this out!
                    330:   - Make platformtest.sh, autogen.sh, and ngircd.init more portable.
                    331:   - Enables "reproducible builds" for ngIRCd: Use the optional BIRTHTIME
                    332:     constant while building ngIRCd, which contains a time stamp for the
                    333:     "Birth Date" information, in seconds since the epoch.
                    334:     See <https://wiki.debian.org/ReproducibleBuilds>.
                    335:   - Update "contrib/ngircd.service" file for systemd.
                    336:   - INSTALL: Add deprecation notice for "PredefChannelsOnly" variable.
                    337:   - Use "NOTICE *" before registration instead of "NOTICE AUTH". "AUTH" is
                    338:     a valid nickname so sending notices to it is probably not a good idea.
                    339:     Use "*" as the target instead as done with numerics when the nick is not
                    340:     available. This mimics the behavior in Charybdis, IRCD-Hybrid, InspIRCd
                    341:     2.2, Plexus 4, etc. Closes #217.
                    342:     The "NoticeAuth" configuration variable (ngircd.conf) has been renamed
                    343:     to "NoticeBeforeRegistration" accordingly, but the old name is still
                    344:     supported for compatibility reasons.
                    345:   - Implement new channel mode "N" (regular users can't change their nick
                    346:     name while on this channel). Closes #214.
                    347:   - README, AUTHORS: Update mailing list and issue tracker URLs.
                    348:   - Remove doc/GIT.txt (it is outdated), update doc/Contributing.txt:
                    349:     ngIRCd uses GitHub, and Git itself is quite common today. So don't
                    350:     include an own Git "mini HowTo" any longer.
                    351:   - Specify session context for OpenSSL clients. This enables some OpenSSL
                    352:     clients, including Pidgin and stunnel 5.06, to reuse a session.
                    353:     Patch by Tom Ryder <tom@sanctum.geek.nz>, thanks! Closes #182.
                    354:   - Keep track of who placed bans, invites, and excepts.
                    355:     Idea and implementation by LucentW, Thanks! Closes #203.
                    356:   - Make setgroups(3) function optional: For example, Interix is missing
                    357:     this function, which prevented ngIRCd to build on this platform. When
                    358:     setgroups(3) isn't available, a warning message is issued on startup.
                    359:   - Implement numeric RPL_LISTSTART(321). lightIRC and other clients
                    360:     expecting RPL_LISTSTART should now behave correctly.
                    361:     Idea and implementation by LucentW, Thanks! Closes #207.
                    362:   - Update ngircd.conf.5: "CloakUserToNick" hides user _and_ real name.
                    363:     This closes #208.
                    364:   - Fix case insensitive pattern matching: Up to now, only the input
                    365:     string became lowercased and was then compared to the pattern -- which
                    366:     failed when the pattern itself wasn't all lowercase!
                    367:   - Streamline the effect of "MorePrivacy" option: Update documentation
                    368:     in ngircd.conf(5); don't hide channels for IRC Ops on LIST and don't
                    369:     hide IP addresses/hostnames on WHOIS when "MorePrivacy" is in effect.
                    370:     This closes #198.
                    371:   - IRC operators now can kick anyone when "OperCanMode" is set.
                    372:     Idea and implementation by LucentW, Thanks! Closes #202.
                    373:   - Implement user mode "I": Hide channels on WHOIS: this mode prevents
                    374:     ngIRCd from showing channels on WHOIS (IRC Operators can always see
                    375:     the channel list).
                    376:     Idea and implementation by LucentW, Thanks! Closes #197.
                    377:   - INVITE command: Implement ERR_USERNOTONSERV(504) numeric and make sure
                    378:     that the target user is on the same server when inviting other users
                    379:     to local ("&") channels.
                    380:     Idea by Cahata, thanks! Closes #183.
                    381:   - INVITE command: Enforce 1 second penalty time, which prevents flooding
                    382:     of the target client.
                    383:     This closes #186. Reported by Cahata, thanks!
                    384:   - MODE command: Always report channel creation time. Up to now when
                    385:     receiving a MODE command, ngIRCd only reported the channel creation
                    386:     time to clients that were members of the channel. This patch reports
                    387:     the channel creation time to all clients, regardless if they are joined

                    389:     This closes #188. Reported by Cahata, thanks!
                    390:   - Update Xcode project for latest Xcode version (6.3).

                    393:
                    394:   - Update doc/Platforms.txt and doc/FAQ.txt.
                    395:   - Fix spelling of RPL_WHOISBOT message text.
                    396:   - Don't send nick name as default PART reason: No other IRC daemon seems
                    397:     to do this (today?). Closes #185.
                    398:     Reported by Cahata in #ngircd, thanks!
                    399:   - Fix "WHO #<chan>" showing invisible users and hiding all visible, the
                    400:     logic was reversed! This bug has been introduced by commit c74115f2,
                    401:     "Simplify mode checking on channels and users within a channel", ngIRCd
                    402:     releases 21, 21.1, and 22 are affected :-( Problem reported by Cahata
                    403:     in #ngircd, Thanks!
                    404:   - Fix typo in src/testsuite/README
                    405:   - Auth PING: Fix our information text for manual sending of "PONG". Up to
                    406:     now, ngIRCd doesn't send a valid IRC command at all, oops!
                    407:   - Auth PING: Fix internal time stamp conversion and don't send a prefix in
                    408:     our PING command. The prefix confuses WeeChat, at least, which doesn't
                    409:     send an appropriate PONG in the case ...
                    410:     Debugging and patch by "wowaname" on #ngircd, thanks!
                    411:   - Fix syntax of ERR_LISTFULL_MSG(478) numeric. Pointed out by "wowaname"
                    412:     in #ngircd, thanks!
                    413:   - Enhance debug messages while sending CHANINFO commands.
                    414:   - Reset "last try" timer when enabling a passive server. This results in
                    415:     a new connection attempt as soon as possible.
                    416:   - Change log message for "Can't resolve address" and for IP address
                    417:     forgeries.
                    418:   - doc/HowToRelease.txt: Add note about the bug tracker.
                    419:   - Update "CipherList" to not enable SSLv3 by default. Idea, initial patch,
                    420:     and testing by Christoph Biedl <ngircd.anoy@manchmal.in-ulm.de>.
                    421:   - Change ngIRCd test suite not to use DNS lookups: Different operating
                    422:     systems do behave quite differently when doing DNS lookups, for example
                    423:     "127.0.0.1" sometimes resolves to "localhost" and sometimes to
                    424:     "localhost.localdomain" (for example OpenBSD). And other OS resolve
                    425:     "localhost" to the real host name (for example Cygwin). So not using
                    426:     DNS at all makes the test site much more portable.
                    427:
                    428: ngIRCd 22 (2014-10-11)
                    429:
                    430:   - Match all list patterns case-insensitive: this affects the invite-,
                    431:     ban-, and except lists, as well as G-Lines an K-Lines.
                    432:     Problem pointed out by "wowaname" on #ngircd, thanks!
                    433:
                    434:   ngIRCd 22~rc1 (2014-09-29)
                    435:   - Sync "except lists" between servers: Up to now, ban, invite, and G-Line
                    436:     lists have been synced between servers while linking -- but obviously
                    437:     nobody noticed that except list have been missing ever since. Until now.
                    438:     Thanks to "j4jackj", who reported this issue in #ngircd.
                    439:   - Allow longer user names (up to 63 characters) for authentication.
                    440:   - Correctly check that a server has a valid hostname and port, thanks to
                    441:     David Binderman <dcb314@hotmail.com> who reported this bug.
                    442:   - Fix the function which generates complete "IRC masks" from user input,
                    443:     don't destroy the source buffer and use all provided parts (nick, user,
                    444:     host name). This fixes GLINEs/KLINEs from not working in some situations.
                    445:   - Increase MAX_SERVERS from 16 to 64: There are installations out there
                    446:     that would like to configure more than 16 links per server, so increase
                    447:     this limit. Best would be to get rid of MAX_SERVERS altogether and make
                    448:     if fully dynamic, but start with this quick and dirty hack ...
                    449:   - Debian: Don't adjust path names that are correct by default and correctly
                    450:     set and use "docdir".
                    451:   - Update config.guess and config.sub to recent versions.
                    452:   - Test suite/platformtest.sh: Detect when tests have been skipped.
                    453:   - doc/Bopm.txt: Update "connregex" and "kline" for current ngIRCd.
                    454:   - Allow "DefaultUserModes" to set all possible modes, including modes only
                    455:     settable by IRC Operators.
                    456:   - Spoofed prefixes: Really kill connection on non-server links.
                    457:   - Implement user mode "F": "relaxed flood protection". Clients with mode
                    458:     "F" set are allowed to rapidly send data to the daemon. This mode is only
                    459:     settable by IRC Operators and can cause problems in the network -- so be
                    460:     careful and only set it on "trusted" clients!
                    461:     User mode "F" is used by Bahamut for this purpose, for example.
                    462:   - Handle "throttling" in a single function: ngIRCd implements "command
                    463:     throttling" and "bps throttling" (bytes per second). The states are
                    464:     detected in different functions, Conn_Handler() and Read_Request(), but
                    465:     handle the actual "throttling" in a common function: this enables us to
                    466:     guarantee consistent behavior and to disable throttling for special
                    467:     connections in only one place
                    468:   - Use server password when PAM is compiled in but disabled.
                    469:   - Streamline punctuation of log messages.
                    470:   - Return ISUPPORT(005) numerics on "VERSION". This is how ircd-seven,
                    471:     Charybdis, Hybrid, and InspIRCd behave, for example.
                    472:   - configure: Only link "contrib/Debian" if it exists, which isn't the case
                    473:     on "VPATH builds", for example.
                    474:   - Show the account name in WHOIS. This uses the same numeric as Charybdis
                    475:     and ircu families: WHOISLOGGEDIN(330).
                    476:   - Pattern matching: Remove "range matching" in our pattern matching code
                    477:     using the "[...]" syntax, because [ and ] are valid characters in nick
                    478:     names and one has to quote them currently using the "\" character, which
                    479:     is quite unexpected for users.
                    480:   - platformtest.sh: New option "-x", don't regenerate build system and
                    481:     allow using separate source and build trees.
                    482:   - Test suite: explicitly enable glibc memory checking.
                    483:   - Make "MODE -k" handling more robust and compatible, send "fake '*' key"
                    484:     in all replies.
                    485:   - Update configure.ng: ngIRCd requires GNU autoconf 2.61 for generating its
                    486:     build system, so update the build system accordingly and implement all
                    487:     changes that autoupdate(1) suggests: Update AC_PREREQ and AC_INIT, use
                    488:     AC_LINK_IFELSE, AC_RUN_IFELSE, and AC_COMPILE_IFELSE, and remove
                    489:     AC_TYPE_SIGNAL (we don't use RETSIGTYPE).
                    490:   - portabtest: Actually test the functions snprintf(), strlcpy(), strlcat(),
                    491:     and vsnprintf() for correctness, not only existence (which was quite
                    492:     useless, because if they weren't available, the program could not have
                    493:     been linked at all ...).
                    494:   - Implement new configuration option "Network": it is used to set the
                    495:     (completely optional) "network name", to which this instance of the
                    496:     daemon belongs. When set, this name is used in the ISUPPORT(005) numeric
                    497:     which is sent to all clients connecting to the server after logging in.
                    498:   - Update doc/Platforms.txt.
                    499:   - Various code cleanups, remove unused code, streamline error handling.
                    500:     Remove all imp.h and exp.h header files, support non-standard vsnprintf()
                    501:     return codes, and fix some K&R C portability issues. Streamline
                    502:     DEBUG_ARRAY, DEBUG_BUFFER, DEBUG_IO, DEBUG_ZIP definitions.
                    503:   - Increase penalty time to 10 seconds when handling OPER commands with an
                    504:     invalid password.
                    505:
                    506: ngIRCd 21.1 (2014-03-25)
                    507:
                    508:   - Don't ignore but use the server password when PAM is compiled in but
                    509:     disabled. Thanks to Roy Sindre Norangshol <roy.sindre@norangshol.no>!
                    510:   - doc/Platforms.txt: Update from master branch.
                    511:   - Really kill connections that send "spoofed prefixes" on non-server links.
                    512:     This fixes commit 6cbe1308 which only killed the connection when the
                    513:     spoofed prefix itself belonged to a non-server client.
                    514:   - CHARCONV command: Fix handling conversion errors, don't overwrite already
                    515:     converted text!
                    516:   - doc/Services.txt: Update information for Anope 2.x.
                    517:   - Correctly use cloaked IRC masks on "INVITE nickname": The cloaked IRC mask
                    518:     of a user is his visible mask, so the daemon has to use it for generating
                    519:     the "one time" entries for the invite list of the given channel, and not
                    520:     the "real" mask which will never match while the target client is "+x", and
                    521:     even worse, will disclose the real mask on "MODE #channel +I" commands :-/
                    522:     Bug reported by Cahata on #ngircd, thanks!
                    523:   - configure: Only link "contrib/Debian" if it exists. This isn't the case on
                    524:     "VPATH builds", for example.
                    525:   - Use $(MKDIR_P) instead of $(mkinstalldirs) in Makefile's and test for
                    526:     "mkdir -p" using AC_PROG_MKDIR_P in "configure".
                    527:   - Fix configure script and "make check" for TCP Wrappers (problems spotted on
                    528:     OpenBSD): add missing #include's and static variables, and add libwrap at
                    529:     the end of the configure run because if libwrap becomes added earlier,
                    530:     other tests may fail.
                    531:   - configure: add support for the LDFLAGS_END and LIBS_END variables to add
                    532:     linker flags and libraries at the end of the configure run (CFLAGS_END has
                    533:     been implemented already).
                    534:   - platformtest.sh and Makefile.am: Don't use "test -e", it isn't portable.
                    535:   - Update Copyright notices for 2014 :-)
                    536:   - Fix permanent {G|K}LINES (with a timeout of 0 seconds).
                    537:   - WEBIRC: Don't set the hostname received by the WEBIRC command when DNS
                    538:     lookups are disabled, but use the IP address instead.
                    539:     Reported by Toni Spets <toni.spets@iki.fi>, thanks!
                    540:   - Check for working getaddrinfo() function: At least AIX 4.3.3 and 5.1 have a
                    541:     broken implementation of getaddrinfo() which doesn't handle "0" as numeric
                    542:     service correctly. This patch adds a configure check for this case and
                    543:     changes all calling functions to only use getaddrinfo() if it "works".
                    544:     See <http://www.stacken.kth.se/lists/heimdal-discuss/2004-05/msg00059.html>
                    545:   - Only use the unsetenv() function when it is available (AIX 4.3 doesn't
                    546:     support it, for example).
                    547:   - Make sure that the source code is still compatible with the "ansi2knr" tool
                    548:     and builds using non-ANSI K&R C compilers. Tested with Apple C on A/UX.
                    549:   - Fix building ngIRCd without support for ZLIB compression.  Reported by
                    550:     "der_baer" on #ngircd, thanks!

                    555:     when (re-)starting ngIRCd.
                    556:   - Change ./contrib/platformtest.sh and update ./doc/Platforms.txt to
                    557:     allow user names up to 8 characters.
                    558:   - Call arc4random_stir() in forked subprocesses, when available. This
                    559:     is required by FreeBSD <10 and current NetBSD at least to correctly
                    560:     initialize the "arc4" random number generator on these platforms.
                    561:   - Update our own Debian package configuration and fix the default path
                    562:     of the "HelpFile" of the "full" package variants.

                    567:   - Use arc4random() function to generate "random" numbers, when available.
                    568:   - platformtest.sh: Detect clang compiler, and clean up GIT source tree

                    570:   - Update (date of) manual pages.
                    571:   - Update "Upgrade Information" in INSTALL file, add more systems to
                    572:     doc/Platforms.txt, and fix spelling in NEWS and ChangeLog files =:)
                    573:   - Fix remaining compiler warnings on OpenBSD.

                    577:   - Adjust log messages for invalid and spoofed prefixes, which cleans up
                    578:     logging of commands related to already KILL'ed clients. And don't
                    579:     forward KILL commands for (already) unknown clients any more to prevent

                    583:   - Fixed blocking of server reconnects in some error configurations.
                    584:   - Don't ignore SSL-related errors during startup any more: abort startup
                    585:     when SSL is requested by the configuration but can't be initialized and
                    586:     don't continue only listening on plain text communication ports.
                    587:     (Closes bug #163)
                    588:   - Implement configurable SSL cipher list selection for GnuTLS and OpenSSL
                    589:     using the new configuration option "CipherList". In addition, this
                    590:     changes the defaults to more secure values: "HIGH:!aNULL:@STRENGTH" for
                    591:     OpenSSL, and "SECURE128" for GnuTLS.
                    592:   - Fix "TRACE": Correctly return ERR_NEEDMOREPARAMS(461) (which basically
                    593:     is "syntax error") when there are too many parameters.
                    594:   - Clean up lots of permission and parameter checks in functions handling
                    595:     IRC commands; and more consistently add penalty times on errors.
                    596:   - Fix error numeric of WHOIS when no nick name has been provided:
                    597:     as per RFC it should be ERR_NONICKNAMEGIVEN(431).
                    598:   - Only log "IDENT ... no result" messages when an IDENT looked took place
                    599:     and didn't return any data, not when IDENT has been disabled.
                    600:   - Show connection flag "s" (SSL) in RPL_TRACE{LINK|SERVER} messages: now
                    601:     you can check if a server-to-server link is SSL-encrypted or not using
                    602:     the IRC "TRACE" command.
                    603:   - Correctly discard supplementary groups on server startup.
                    604:   - Save client IP address text for "WebIRC" users and correctly display
                    605:     it on WHOIS, for example. (Closes bug #159)
                    606:   - Implement the new configuration option "DefaultUserModes" which lists
                    607:     user modes that become automatically set on new local clients right
                    608:     after login. Please note that only modes can be set that the client
                    609:     could set on itself, so you can't set "a" (away) or "o" (IRC Op),
                    610:     for example! User modes "i" (invisible) or "x" (cloaked) etc. are
                    611:     "interesting", though. (Closes bug #160)
                    612:   - Add support for the new METADATA "account" property, which allows
                    613:     services to automatically identify users after netsplits and across
                    614:     service restarts.
                    615:   - Enforce "penalty times" on error conditions more consistently and in
                    616:     more places. Now most error codes sent back from the IRC server to the
                    617:     client should result in a 2 second "penalty".
                    618:   - Implement a new configuration option "AllowedChannelTypes" that lists
                    619:     all allowed channel types (channel prefixes) for newly created channels
                    620:     on the local server. By default, all supported channel types are allowed.
                    621:     If set to the empty string, local clients can't create new channels at
                    622:     all, which equals the old "PredefChannelsOnly = yes" setting.
                    623:     This change deprecates the "PredefChannelsOnly" variable, too, but it is
                    624:     still supported and translated to the appropriate "AllowedChannelTypes"
                    625:     setting. When the old "PredefChannelsOnly" variable is processed, a
                    626:     warning message is logged. (Closes bug #152)
                    627:   - Add support for "client certificate fingerprinting". When a client
                    628:     passes an SSL certificate to the server, the "fingerprint" will be
                    629:     forwarded in the network which enables IRC services to identify the
                    630:     user using this certificate and not using passwords.
                    631:   - IRC Operator names, as defined in ngircd.conf, are logged now when
                    632:     handling successful OPER commands.
                    633:   - Some error conditions while handling IRC commands, like "permission
                    634:     denied" or "need more parameters", result in more penalty times.
                    635:   - The numeric replies of some commands became split too early which
                    636:     resulted in more numeric reply lines than necessary.
                    637:   - Implement a new configuration option "IncludeDir" in the "[Options]"
                    638:     section that can be used to specify a directory which can contain
                    639:     further configuration files and configuration file snippets matching
                    640:     the pattern "*.conf". These files are read in after the main server
                    641:     configuration file ("ngircd.conf" by default) has been read in and
                    642:     parsed.  The default is "$SYSCONFDIR/ngircd.conf.d", so that it is
                    643:     possible to adjust the configuration only by placing additional files
                    644:     into this directory. (Closes bug #157)
                    645:   - Fix use-after-free in the Lists_CheckReason() function, which is used
                    646:     to check if a client is a member of a particular ban/invite/... list.
                    647:   - Xcode: fix detection of host OS, vendor, and CPU type, and update
                    648:     project settings for Xcode 5.
                    649:   - OS X PackageMaker: use relative path names in project files and package
                    650:     with correct file permissions (requires root privileges on "make").
                    651:   - Add Travis-CI configuration file (".travis.yml") to project.
                    652:   - Look for possible cloaked Masks in Lists. Users with +x user mode can
                    653:     be banned with their cloaked hostname now.
                    654:   - Don't read SSL client data before DNS resolver is finished which could
                    655:     have resulted in discarding the resolved client hostname and IDENT
                    656:     reply afterwards, because in some situations (timing dependent) the
                    657:     NICK and USER commands could have already been read in from the client,
                    658:     stored in the buffer, and been processed.
                    659:     Thanks to Julian Brost for reporting the issue and testing, and to
                    660:     Federico G. Schwindt <fgsch@lodoss.net> for helping to debug it!
                    661:   - Increase password length limit to 64 characters. (Closes bug #154)
                    662:   - doc/Services.txt: Update Anope status and URL.
                    663:   - Clean up Xcode project file, remove outdated files, add missing ones.
                    664:   - Update Doxygen configuration file.
                    665:   - configure: search for iconv_open as well as libiconv_open, because
                    666:     on some installations iconv_open() is actually libiconv_open().
                    667:     iconv_open() is the glibc version while libiconv_open() is the
                    668:     libiconv version, now both variants are supported. (Closes bug #151)
                    669:   - ngIRCd now accepts user names including "@" characters, saves the
                    670:     unmodified name for authentication but stores only the part in front
                    671:     of the "@" character as "IRC user name". And the latter is how
                    672:     ircd2.11, Bahamut, and irc-seven behave as well. (Closes bug #155)
                    673:   - Lots of IRC "information functions" like ADMIN, INFO, ... now accept
                    674:     server masks and names of connected users (in addition to server names)
                    675:     for specifying the target server of the command. (Closes bug #153)
                    676:   - Implement a new configuration option "IdleTimeout" in the "[Limits]"
                    677:     section of the configuration file which can be used to set a timeout
                    678:     in seconds after which the whole daemon will shutdown when no more
                    679:     connections are left active after handling at least one client.
                    680:     The default is 0, "never".
                    681:     This can be useful for testing or when ngIRCd is started using "socket
                    682:     activation" with systemd(8), for example.
                    683:   - Implement support for systemd(8) "socket activation".
                    684:   - contrib/README: add description for more files.
                    685:   - Enable WHOIS to display information about IRC Services using the new
                    686:     numeric 310(RPL_WHOISSERVICE) This numeric is used for this purpose by
                    687:     InspIRCd, for example -- but as usual, other numerics are in use, too,
                    688:     like 613 in UltimateIRCd ...
                    689:     Please note that neither the Operator (+o) not the "bot status" (+B)
                    690:     of an IRC service is displayed in the output.
                    691:   - Exit message: use singular & plural :-)
                    692:   - autogen.sh: Check for autoconf/automake wrapper scripts
                    693:   - Add missing punctuation marks in log messages, adjust some severity
                    694:     levels, and make SSL-related messages more readable.
                    695:   - AUTHORS file: Update list of contributors.
                    696:   - Update systemd(8) example configuration files in ./contrib/ directory:
                    697:     the "ngircd.service" file now uses the "forking" service type which
                    698:     enhances the log messages shown by "systemctl status ngircd.service",
                    699:     and the new "ngircd.socket" file configures a systemd socket that
                    700:     configures a socket for ngIRCd and launches the daemon on demand.
                    701:   - Enhance help system and the HELP command: now a "help text file" can be
                    702:     set using the new configuration option "HelpFile" ("global" section),
                    703:     which is read in and parsed on server startup and configuration reload,
                    704:     and then is used to output individual help texts to specific topics.
                    705:     Please see the file ./doc/Commands.txt for details.

                    708:
                    709:   - Security: Fix a denial of service bug (server crash) which could happen
                    710:     when the configuration option "NoticeAuth" is enabled (which is NOT the
                    711:     default) and ngIRCd failed to send the "notice auth" messages to new
                    712:     clients connecting to the server (CVE-2013-5580).
                    713:
                    714: ngIRCd 20.2 (2013-02-15)
                    715:
                    716:   - Security: Fix a denial of service bug in the function handling KICK
                    717:     commands that could be used by arbitrary users to crash the daemon
                    718:     (CVE-2013-1747).
                    719:   - WHO command: Use the currently "displayed hostname" (which can be cloaked!)
                    720:     for hostname matching, not the real one. In other words: don't display all
                    721:     the cloaked users on a specific real hostname!
                    722:   - configure: The header file "netinet/in_systm.h" already is optional in
                    723:     ngIRCd, so don't require it in the configure script. Now ngIRCd can be
                    724:     built on Minix 3 again :-)
                    725:   - Return better "Connection not registered as server link" errors: Now ngIRCd
                    726:     returns a more specific error message for numeric ERR_NOTREGISTERED(451)
                    727:     when a regular user tries to use a command that isn't allowed for users but
                    728:     for servers.
                    729:   - Don't report ERR_NEEDMOREPARAMS(461) when a MDOE command with more modes
                    730:     than nicknames is handled, as well as for channel limit and key changes
                    731:     without specifying the limit or key parameters.
                    732:     This is how a lot (all?) other IRC servers behave, including ircd2.11,
                    733:     InspIRCd, and ircd-seven. And because of clients (tested with Textual and
                    734:     mIRC) sending bogus MODE commands like "MODE -ooo nick", end-users got the
                    735:     expected result as well as correct but misleading error messages ...
                    736:   - Correctly detect when SSL subsystem must be initialized and take
                    737:     outgoing connections (server links!) into account, too.
                    738:   - autogen.sh: Enforce serial test harness on GNU automake >=1.13. The
                    739:     new parallel test harness which is enabled by default starting with
                    740:     automake 1.13 isn't compatible with our test suite.
                    741:     And don't use "egrep -o", instead use "sed", because it isn't portable
                    742:     and not available on OpenBSD, for example.
                    743:
                    744: ngIRCd 20.1 (2013-01-02)
                    745:
                    746:   - Allow ERROR command on server and service links only, ignore them and
                    747:     add a penalty time on all other link types.
                    748:   - Enforced mode setting by IRC Operators: Only check the channel user
                    749:     modes of the initiator if he is joined to the channel and not an IRC
                    750:     operator enforcing modes (which requires the configuration option
                    751:     "OperCanUseMode" to be enabled), because trying to check channel user
                    752:     modes of a non-member results in an assertion when running with debug
                    753:     code or could crash the daemon otherwise. This closes bug #147, thanks
                    754:     to James Kirwill <james.kirwill@bk.ru> for tracking this down!
                    755:   - Fix build system to cope with spaces in path names.
                    756:   - Code cleanups, mostly to fix build warnings on Cygwin.
                    757:
                    758: ngIRCd 20 (2012-12-17)
                    759:
                    760:   - Allow user names ("INDENT") up to 20 characters when ngIRCd has not
                    761:     been configured for "strict RFC mode". This is useful if you are using
                    762:     external (PAM) authentication mechanisms that require longer user names.
                    763:     Patch suggested by Brett Smith <brett@w3.org>, see
                    764:     <http://arthur.barton.de/pipermail/ngircd-ml/2012-October/000579.html>.
                    765:
                    766:   ngIRCd 20~rc2 (2012-12-02)
                    767:   - Rework cloaked hostname handling and implement the "METADATA cloakhost"
                    768:     subcommand: Now ngIRCd uses two fields internally, one to store the
                    769:     "real" hostname and one to save the "cloaked" hostname. This allows
                    770:     "foreign servers" (aka "IRC services") to alter the real and cloaked
                    771:     hostnames of clients without problems, even when the user itself issues
                    772:     additional "MODE +x" and "MODE -x" commands.
                    773:   - RPL_UMODEIS: send correct target name, even on server links.
                    774:   - Update platformtest.sh to follow autoconf changes and only generate
                    775:     the "configure" script when it is missing.
                    776:   - Fix the test suite to correctly execute test scripts even when stdout
                    777:     is redirected.
                    778:   - Fix some compiler warnings on NetBSD and OpenBSD.
                    779:
                    780:   ngIRCd 20~rc1 (2012-11-11)
                    781:   - Update doc/Services.txt: describe the upcoming version of Anope 1.9.8,
                    782:     then including a protocol module for ngIRCd. And remove our own patches
                    783:     in ./contrib/Anope because they aren't supported any more ...
                    784:   - Implement new "METADATA" command which can be used by remote servers
                    785:     and IRC services to update client metadata like the client info text
                    786:     ("real name"), user name, and hostname, and use this command to
                    787:     configure an cloaked hostname (user mode "+x") on remote servers:
                    788:     This prevents "double cloaking" of hostnames and even cloaked
                    789:     hostnames are in sync on all servers supporting "METADATA" now.
                    790:   - Fix error message when trying to join non-predefined channels and the
                    791:     "PredefChannelsOnly" configuration option is set.
                    792:   - Implement new IRC "SVSNICK" command to allow remote servers (and IRC
                    793:     services) to change nicknames of already registered users. The SVSNICK
                    794:     command itself doesn't change the nickname, but it becomes forwarded
                    795:     to the server to which the user is connected to. And then this server
                    796:     initiates the real nickname changing using regular NICK commands.
                    797:     This allows to run mixed networks with old servers not supporting the
                    798:     SVSNICK command, because SVSNICK commands for nicknames on such servers
                    799:     are silently ignored and don't cause a desynchronization of the network.
                    800:   - Make server reconnect time a little bit more random, so that two
                    801:     servers trying to connect to each other asynchronously don't try this
                    802:     in exactly the same time periods and kick each other off ...
                    803:   - Don't accept connections for servers already being linked: there was a
                    804:     time frame that could result in one connection overwriting the other,
                    805:     e. g. the incoming connection overwriting the status of the outgoing
                    806:     one. And this could lead to all kind of weirdness (even crashes!) later
                    807:     on: now such incoming connections are dropped.
                    808:   - New configuration option "MaxListSize" to configure the maximum number
                    809:     of channels returned by a LIST command. The default is 100, as before.
                    810:   - Implement user mode "b", "block messages": when a user has set mode "b",
                    811:     all private messages and notices to this user are blocked if they don't
                    812:     originate from a registered user, an IRC Op, server or service. The
                    813:     originator gets an error numeric sent back in this case,
                    814:     ERR_NONONREG_MSG (486), which is used by UnrealIRCd, too. (Closes #144)
                    815:   - WHOIS: Not only show RPL_WHOISHOST_MSG to local IRC operators, but show
                    816:     it to all IRC operators in the network. And don't show it to anybody if
                    817:     the "more privacy" configuration option is enabled. (Closes #134)
                    818:   - Test suite: make expect scripts more verbose displaying dots for each
                    819:     reply of the server that it is waiting for.
                    820:   - WHOIS: Implement numeric RPL_WHOISMODES_MSG (379) and show user modes in
                    821:     the reply of the WHOIS command for the user himself or, if MorePrivacy
                    822:     isn't set, for request initiated by an IRC operator. (Closes #129)
                    823:   - Implement channel mode "V" (invite disallow): If the new channel mode
                    824:     "V" is set, the INVITE command becomes invalid and all clients get the
                    825:     new ERR_NOINVITE_MSG (518) reply. (Closes #143)
                    826:   - KICK-protect IRC services.
                    827:   - Implement channel mode "Q" and user mode "q": Both modes protect users
                    828:     from channel kicks: only IRC operators and servers can kick users having
                    829:     mode "q" or in channels with mode "Q". (Closes #141)
                    830:   - Debian: require "telnet" or "telnet-ssl" for building and enable
                    831:     CHARCONV in ngircd-full[-dbg] variants.
                    832:   - Send RPL_REHASHING (382) numeric if a REHASH command was accepted.
                    833:   - Fix spelling and variable names in some log messages.
                    834:   - Allow users to "cloak" their hostname only when the configuration
                    835:     variable "CloakHostModeX" (introduced in 19.2) is set. Otherwise, only
                    836:     IRC operators, other servers, and services are allowed to set the user
                    837:     mode "+x": this prevents regular users from changing their hostmask to
                    838:     the name of the IRC server itself, which confused quite a few people ;-)
                    839:     (Closes #133)
                    840:   - New configuration option "OperChanPAutoOp": If disabled, IRC operators
                    841:     don't become channel operators in persistent channels when joining.
                    842:     Enabled by default, which has been the behavior of ngIRCd up to this
                    843:     patch. (Closes #135)
                    844:   - Allow IRC operators to see secret (+s) channels in LIST command as long
                    845:     as the "MorePrivacy" configuration option isn't enabled in the
                    846:     configuration file. (Closes #136)
                    847:   - Enhance build system: Support new (>=1.12) and old (<=1.11) GNU automake
                    848:     versions, update checks for required and optional features, enable
                    849:     colored test output of automake (if available), rename configure.in to
                    850:     more modern configure.ac, include .mailmap and all build-system files in
                    851:     distribution archives and no longer require a GIT tree to detect the
                    852:     correct version string.
                    853:   - Update documentation: add doc/Contributing.txt and include version
                    854:     numbers in doc/Modes.txt.
                    855:   - Free all listen ports on initialization: now listen ports can be
                    856:     reconfigured on runtime using a configuration reload.
                    857:   - Initialize SSL when needed only, and disable SSL on errors.
                    858:   - Implement new (optional) IRC+ "CHARCONV" command to set a client
                    859:     character set that the server translates all messages to/from UTF-8.
                    860:     This feature requires the "libiconv" library and must be enabled using
                    861:     the new "--with-iconv" option of the ./configure script. See
                    862:     doc/Protocol.txt for details. (Closes #109)
                    863:   - Allow limited punctuation in usernames, for better PAM integration.
                    864:   - Correctly re-initialize signal handlers on RESTART commands.
                    865:   - Show a warning on startup if the configuration file is not a full path:
                    866:     ngIRCd is a long-running process and changes its working directory to
                    867:     "/" to not block mounted filesystems and the like when running as daemon
                    868:     ("not in the foreground"); therefore the path to the configuration file
                    869:     must be relative to "/" (or the chroot() directory), which basically is
                    870:     "not relative", to ensure that "kill -HUP" and the "REHASH" command work
                    871:     as expected later on. (Closes #127)
                    872:   - Make the "&SERVER" channel definable in a [Channel] configuration block,
                    873:     which enables server operators to overwrite the built-in topic and
                    874:     channel modes. (Closes #131)
                    875:   - Don't limit list size of "WHO #channel" commands, because it makes no
                    876:     sense to not return all the users in that channel, so I removed the
                    877:     check. But if there are more than MAX_RPL_WHO(25) replies, the client
                    878:     requesting the list will be "penalized" one second more, then 2 in
                    879:     total. (Closes #125)
                    880:   - Make ngIRCd buildable using the kqueue() IO interface on FreeBSD 4.x.
                    881:   - Fix the "NoticeAuth" configuration option when using SSL connections and
                    882:     enhance the message to show the hostname and IDENT reply of the client.
                    883:   - Introduce numeric RPL_HOSTHIDDEN_MSG (396): This numeric is sent to the
                    884:     client each time it changes its displayed hostname using "MODE +/-x",
                    885:     and if "CloakHost" is set right after the MOTD has been sent.
                    886:   - Fix USERHOST not displaying the correctly cloaked hostname.
                    887:   - Implement user mode "B" ("Bot flag"): it is settable and unsettable by
                    888:     every (non-restricted) client. This is how Unreal and InspIRCd do
                    889:     behave, and so do we :-)
                    890:   - Dynamically allocate memory for connection passwords: This a) saves
                    891:     memory for clients not using passwords at all and b) allows for
                    892:     "arbitrarily" long passwords.
                    893:   - Implement channel mode "M": Only the server, identified users and IRC
                    894:     operators are able to talk in such a channel.
                    895:   - Block nicknames that are reserved for services and are defined using the
                    896:     configuration variable "ServiceMask" in "Server" blocks; And this
                    897:     variable now can handle more than one mask separated by commas.
                    898:   - Now "make uninstall" removes the installed "ngircd.conf" file, if it is
                    899:     still equal to our "sample-ngircd.conf" file and therefore hasn't been
                    900:     modified by the user. If it has been modified, it isn't removed and a
                    901:     notice is displayed to the user. And "make install" now displays a
                    902:     message when no ngircd.conf file exists and the "sample-ngircd.conf"
                    903:     file will be installed as a starting point.
                    904:   - Add contrib/ngircd.service, a systemd service file for ngircd.
                    905:   - Implemented XOP channel user modes: "Half Op" ("+h", prefix "%") can set
                    906:     the channel modes +imntvIbek and kick all +v and normal users; "Admin"
                    907:     ("+a", prefix "&") can set channel modes +imntvIbekoRsz and kick all +o,
                    908:     +h, +v and normal users; and "Owner" ("+q", prefix "~") can set channel
                    909:     modes +imntvIbekoRsz and kick all +a, +o, +h, +v and normal users.
                    910:   - Implement hashed cloaked hostnames for both the "CloakHost" and
                    911:     "CloakHostModeX" configuration options: now the admin can use the new
                    912:     '%x' placeholder to insert a hashed version of the clients hostname,
                    913:     and the new configuration option "CloakHostSalt" defines the salt for
                    914:     the hash function. When "CloakHostSalt" is not set (the default), a
                    915:     random salt will be generated after each server restart. (Closes #133)

                    918:
                    919:   - doc/Capabilities.txt: document "multi-prefix" capability
                    920:
                    921:   ngIRCd 19.2~rc1 (2012-06-13)
                    922:   - New configuration option "CloakHostModeX" to configure the hostname
                    923:     that gets used for IRC clients which have user mode "+x" enabled.
                    924:     Up to now, the name of the IRC server itself has been used for this,
                    925:     which still is the default when "CloakHostModeX" isn't set.
                    926:   - Correctly handle asynchronously re-established server links: a race
                    927:     condition could let the daemon loose track of an already re-established
                    928:     incoming server link while preparing its own outgoing connection.
                    929:     Peers that both try to connect each other could have been affected.
                    930:   - Log a debug message when SIGUSR2 is handled in debug mode.
                    931:   - Only allow alphanumeric characters in user-supplied user names of
                    932:     USER command and IDENT replies.
                    933:   - Change wording of "TLS initialized" message to make it more consistent.
                    934:   - Don't leak file descriptors on error path when creating "PID files".
                    935:   - Add missing mode "r" to CHANMODES in 005 "ISUPPORT" numeric.
                    936:   - Update doc/Modes.txt and doc/Platforms.txt documents.
                    937:   - contrib/platformtest.sh: correctly detect Open64 C compiler and handle
                    938:     "CC=xxx MAKE=yyy ./platformtest.sh" calling convention.
                    939:   - Add instructions for setting up Atheme IRC services.
                    940:   - Implement support for IRC capability handling, the new "CAP" command,
                    941:     and capability "multi-prefix" which allows both the NAME and WHO command
                    942:     handlers to return more than one "class prefix" to the client.
                    943:   - Update Xcode project files: reference missing documentation files.
                    944:   - Fix: Don't ignore "permission denied" errors when enabling chroot.
                    945:   - FAQ: enhance description of chroot setup.

                    948:
                    949:   - Fix gcc warning (v4.6.3), initialize "list" variable to NULL.
                    950:   - Fix typos: "recieved" -> "received", "Please not" -> "Please note",
                    951:     and fix lintian(1) warning ""hyphen-used-as-minus-sign", too.
                    952:   - Really include _all_ patches to build the Anope module into the
                    953:     distribution archive ... ooops!
                    954:   - getpid.sh: Fix test case error for Debian using sbuild(1).
                    955:   - Don't log "ngIRCd hello message" two times when starting up.

                    958:
                    959:   - Update build system: bump config.guess and config.sub files used by
                    960:     GNU autoconf/automake to recent versions.
                    961:   - Fix configuration file parser: don't accept "[SSL]" blocks in the
                    962:     configuration file when no SSL support is built in ngIRCd.
                    963:   - Fix building ngIRCd with old gcc versions (e. g. 2.7.2).
                    964:   - Correctly re-open syslog logging after reading of configuration
                    965:     file: Syslog logging has been initialized before reading the
                    966:     configuration, so ngIRCd always used the default facility and ignored
                    967:     the "SyslogFacility" configuration option ...

                    970:   ngIRCd 19~rc1 (2012-02-12)
                    971:   - Enhance command limits for server links: the limit now is dependent
                    972:     on the number of users connected in the network and higher while
                    973:     servers are joining the network to make the login of servers faster.
                    974:   - Log more information about server synchronization.
                    975:   - Update preliminary ngIRCd protocol module for Anope 1.9.6, which now
                    976:     is the only supported version.
                    977:   - New numeric RPL_WHOISHOST_MSG(378), which returns the DNS host name
                    978:     (if available) and the IP address of a client in the WHOIS reply.
                    979:     Only the user itself and local IRC operators get this numeric.
                    980:   - Implement channel exception list (mode 'e'). This allows a channel
                    981:     operator to define exception masks that allow users to join the
                    982:     channel even when a "ban" would match and prevent them from joining:
                    983:     the exception list (e) overrides the ban list (b).
                    984:   - PRIVMSG and NOTICE: Handle nick!user@host masks case-insensitive.
                    985:   - Implement user mode 'C': If the target user of a PRIVMSG or NOTICE
                    986:     command has the user mode 'C' set, it is required that both sender
                    987:     and receiver are on the same channel. This prevents private flooding
                    988:     by completely unknown clients.
                    989:   - New RPL_WHOISREGNICK_MSG(307) numeric in WHOIS command replies: it
                    990:     indicates if a nickname is registered (if user mode 'R' set).
                    991:   - Limit channel invite, ban, and exception lists to 50 entries and fix
                    992:     duplicate check and error messages when adding already listed entries
                    993:     or deleting no (longer) existing ones.
                    994:   - Fix both ERR_SUMMONDISABLED(445) and ERR_USERSDISABLED(446) replies.
                    995:   - MODE command: correctly return ERR_UNKNOWNMODE(472) numeric for
                    996:     unknown channel modes, instead of ERR_UMODEUNKNOWNFLAG(501).
                    997:   - ISUPPORT(005) numeric: add "O", "R", and "z" modes to "CHANMODES",
                    998:     add "EXCEPTS=e" and "INVEX=I", add "MAXLIST=beI:50".
                    999:   - Limit the number of list items in the reply of LIST (100), WHO (25),
                   1000:     WHOIS (10), and WHOWAS (25) commands.
                   1001:   - LIST command: compare pattern case insensitive.
                   1002:   - Limit the MODE command to handle a maximum number of 5 channel modes
                   1003:     that require an argument (+Ibkl) per call and report this number
                   1004:     in the ISUPPORT(005) numeric: "MODES=5".
                   1005:   - Fix handling of channel mode sequence with/without arguments.
                   1006:     For example, don't generate wrong error messages when handling
                   1007:     "MODE #chan +IIIIItn *!aa@b *!bb@c *!cc@d *!dd@e *!ee@f".
                   1008:   - When sending data on a connection, only try to get the type of
                   1009:     the client if there still is one assigned. This could trigger an
                   1010:     assertion and end the daemon in some error paths.
                   1011:   - Don't try to close already closed/invalid sockets to forked child
                   1012:     processes. This could potentially crash the daemon in some cases
                   1013:     with IDENT lookups enabled.
                   1014:   - WHOIS command: make sure that the reply ends with RPL_ENDOFWHOIS,
                   1015:     don't answer queries for IRC servers, make sure mask matching is
                   1016:     case-insensitive, and that RPL_ENDOFWHOIS numeric is sent with the
                   1017:     unmodified mask (like it has been received from the client).
                   1018:   - LINKS command: support <mask> parameter to limit the reply.
                   1019:   - Add 1 second penalty for every further target on PRIVMSG/NOTICE
                   1020:     commands: this reduces the possibility of flooding channels with
                   1021:     commands like "PRIVMSG/NOTICE #a,#n,#c,... :message" a little bit.
                   1022:     Problem noticed by Cahata, thanks!
                   1023:   - Display correct error message when "Server{UID|GID}" variable in the
                   1024:     configuration file is invalid (not a number and no existing user).
                   1025:   - Update Copyright notices for 2012 :-)
                   1026:   - JOIN command: don't stop handling of channel lists when a single
                   1027:     channel cannot be joined (because of bad name, wrong key or channel
                   1028:     limit reached), but report an error and continue. And don't check
                   1029:     the channel limit and don't report with "too many channels" when
                   1030:     trying to join a channel that the client already is a member of.
                   1031:   - ISON command: reply with the correct upper-/lowercase nicknames.
                   1032:   - New configuration option "PAMIsOptional": when set, clients not
                   1033:     sending a password are still allowed to connect: they won't become
                   1034:     "identified" and keep the "~" character prepended to their supplied
                   1035:     user name. See "man 5 ngircd.conf" for details.
                   1036:   - Fixed handling of WHO commands. This fixes two bugs: "WHO <nick>"
                   1037:     returned nothing at all if the user was "+i" (reported by Cahata,
                   1038:     thanks) and "WHO <nick|nickmask>" returned channel names instead
                   1039:     of "*" when the user was member of a (visible) channel.
                   1040:   - Fixed some spelling errors in documentation and code comments
                   1041:     (Thanks to Christoph Biedl).
                   1042:   - contrib/Debian/control: Update and complete "Build-Depends" and
                   1043:     update our Debian package descriptions with "official" ones.
                   1044:   - Fixed typo in two error messages.
                   1045:   - LUSERS reply: only count channels that are visible to the requesting
                   1046:     client, so the existence of secret channels is no longer revealed by
                   1047:     using LUSERS. Reported by Cahata, thanks!
                   1048:   - Unknown user and channel modes no longer stop the mode parser, but
                   1049:     are simply ignored. Therefore modes after the unknown one are now
                   1050:     handled. This is how ircd2.10/ircd2.11/ircd-seven behave, at least.
                   1051:     Reported by Cahata, thanks!
                   1052:   - README: Update list of implemented commands.
                   1053:   - Log better error messages when rejecting clients.
                   1054:   - Implement IRC commands "GLINE" and "KLINE" to ban users. G-Lines are
                   1055:     synchronized between server on peering, K-Lines are local only.
                   1056:     If you use "*!<user>@<host>" or "*!*@<host>" masks, these connections
                   1057:     are blocked even before the user is fully logged in (before PASS,
                   1058:     NICK, and USER commands have been processed) and before the child
                   1059:     processes for authentication are forked, so resource usage is smaller.
                   1060:   - Xcode: update project file for Xcode 4.2 and define HAVE_GAI_STRERROR
                   1061:     for Mac OS X Xcode builds.
                   1062:   - ./configure: Fix logic and quoting of poll() detection code: only use
                   1063:     poll() when poll.h exists as well.
                   1064:   - Suppress 'Can't create pre-defined channel: invalid name: ""' message.
                   1065:   - whois-test: handle local host name = "localhost.localdomain" using the
                   1066:     pattern "localhost*" for valid local host names.
                   1067:   - sample-ngircd.conf: show correct default for "PAM" variable: The
                   1068:     default of "PAM" is "yes" when ngIRCd has been configured to use it,
                   1069:     so show the correct default value in the sample configuration file.
                   1070:     (Closes #119)
                   1071:   - Update GPL 2 license text to current version.
                   1072:   - Only close "unrelated" sockets in forked child processes: This fixes
                   1073:     the problem that ngIRCd can't do any IDENT lookups because of the
                   1074:     socket has already been closed in the child process.
                   1075:     The bug has been introduced starting with ngIRCd 17 ... :-(
                   1076:     (commit ID 6ebb31ab35e)
                   1077:   - Added doc/Modes.txt: document modes supported by ngIRCd.
                   1078:   - Implement user mode "R": indicates that the nickname of this user
                   1079:     is "registered". This mode isn't handled by ngIRCd itself, but must
                   1080:     be set and unset by IRC services like Anope.
                   1081:   - Implement channel mode "R": only registered users (having the user
                   1082:     mode "R" set) are allowed to join this channel.
                   1083:   - Test suite: bind to loopback (127.0.0.1) interface only.
                   1084:   - New 2nd message "Nickname too long" for error code 432.
                   1085:   - Xcode: Mac OS X config.h: support 10.5 as well as 10.6/10.7 SDK.
                   1086:   - Xcode: exclude more Xcode 4 specific directories in ".gitignore".
                   1087:   - Disconnect directly linked servers sending QUIT. Without this,
                   1088:     the server becomes removed from the network and the client list,
                   1089:     but the connection isn't shut down at all ...
                   1090:   - contrib/ngindent: detect "gindent" as GNU indent.
                   1091:   - Handle unknown user and channel modes: these modes are saved and
                   1092:     forwarded to other servers, but ignored otherwise.
                   1093:   - Handle channel user modes 'a', 'h', and 'q' from remote servers.
                   1094:     These channel user modes aren't used for anything at the moment,
                   1095:     but ngIRCd knows that these three modes are "channel user modes"
                   1096:     and not "channel modes", that is that these modes take an "nickname"
                   1097:     argument. Like unknown user and channel modes, these modes are saved
                   1098:     and forwarded to other servers, but ignored otherwise.
                   1099:   - Correctly inform clients when other servers change their user modes.
                   1100:     This is required for some services to work correctly.
                   1101:   - Test suite: make getpid.sh work even when run as root.
                   1102:   - Spoofed prefixes: close connection on non-server links only.
                   1103:     On server-links, spoofed prefixes can happen because of the
                   1104:     asynchronous nature of the IRC protocol. So don't break server-
                   1105:     links, only log a message and ignore the command. (Closes #113)
                   1106:
                   1107: ngIRCd 18 (2011-07-10)
                   1108:
                   1109:   - Update timestamp of ngircd(8) manual page.
                   1110:   - Add preliminary ngIRCd protocol module for Anope 1.9 to contrib/Anope/.
                   1111:   - Don't register WHOWAS information when "MorePrivacy" option is in effect.
                   1112:
                   1113:   ngIRCd 18~rc2 (2011-06-29)
                   1114:   - Update documentation, fix some wording, and use a spellchecker :-)
                   1115:   - ngircd.conf.5: strip "SSL" prefix from variables in [SSL] section.
                   1116:   - ngircd.8: document debugging options.
                   1117:   - GnuTLS: use 1024 bits as minimum size of the DH prime. This enables
                   1118:     ngIRCd to accept incoming connections from other servers and clients
                   1119:     that "only" use at least 1024 bits again, like ngIRCd 17 did (and no
                   1120:     longer requires 2048 bits for incoming connections).
                   1121:
                   1122:   ngIRCd 18~rc1 (2011-06-27)
                   1123:   - PAM warning message: make clear which "Password" config option is ignored.
                   1124:   - New configuration option "MorePrivacy" to "censor" some user information.
                   1125:     When enabled, signon time and idle time is left out. Part and quit
                   1126:     messages are made to look the same. WHOWAS requests are silently dropped.
                   1127:     All of this is useful if one wish to conceal users that access the ngircd
                   1128:     servers from TOR or I2P.
                   1129:   - New configuration option "ScrubCTCP" to scrub incoming CTCP commands. If
                   1130:     activated, the server silently drops incoming CTCP requests from both
                   1131:     other servers and from users. The server that scrubs CTCP will not forward
                   1132:     the CTCP requests to other servers in the network either, which can spell
                   1133:     trouble if not every oper knows about the CTCP-scrubbing. Scrubbing CTCP
                   1134:     commands also means that it is not possible to send files between users.
                   1135:     There is one exception to the CTCP scrubbing performed: ACTION ("/me
                   1136:     commands") requests are not scrubbed.
                   1137:   - Display configuration errors more prominent on "--configtest".
                   1138:   - Restructure ngIRCd configuration file: introduce new [Limits], [Options],
                   1139:     and [SSL] sections. The intention of this restructuring is to make the
                   1140:     [Global] section much cleaner, so that it only contains variables that
                   1141:     most installations must adjust to the local requirements. All the optional
                   1142:     variables are moved to [Limits], for configurable limits and timers of
                   1143:     ngIRCd, and [Options], for optional features. All SSL-related variables
                   1144:     are moved to [SSL] and the "SSL"-prefix is stripped. The old variables in
                   1145:     the [Global] section are deprecated now, but are still recognized.
                   1146:     => Don't forget to check your configuration, use "ngircd --configtest"!
                   1147:   - New documentation "how to contribute": doc/Contributing.txt.
                   1148:   - Slightly fix error handling when connecting to remote servers.
                   1149:   - GnuTLS: bump DH-bitsize to 2048: this solves the problem that some clients
                   1150:     refuse to connect to severs that only offer 1024. For interoperability it
                   1151:     would be best to just use 4096 bits, but that takes minutes, even on
                   1152:     current hardware ...
                   1153:   - contrib/platformtest.sh: fix gcc version detection.
                   1154:   - Avoid needlessly scary 'buffer overflow' messages: When the write buffer
                   1155:     space grows too large, ngIRCd has to disconnect the client to avoid
                   1156:     wasting too much memory, which is logged with a scary 'write buffer
                   1157:     overflow' message. Change this to a more descriptive wording.
                   1158:   - Require server prefixes for most commands on RFC2812 links. RFC1459 links
                   1159:     (often used by services, for example) are not affected.
                   1160:   - Mac OS X: update installer functionality, texts, and add our logo :-)
                   1161:   - New configuration option "RequireAuthPing": PING-PONG on login. When
                   1162:     enabled, this configuration option lets ngIRCd send a PING with an numeric
                   1163:     "token" to clients logging in; and it will not become registered in the
                   1164:     network until the client responds with the correct PONG.
                   1165:   - New configuration option "NoticeAuth": send NOTICE AUTH on connect. When
                   1166:     active, ngircd will send "NOTICE AUTH" messages on client connect time
                   1167:     like e.g. snircd (QuakeNet) does.
                   1168:   - Generate WALLOPS message on SQUIT from IRC operators; so SQUIT now behaves
                   1169:     like CONNECT and DISCONNECT commands, when called by an IRC operator.
                   1170:   - Allow servers to send more commands in the first 10 seconds ("burst"). This
                   1171:     helps to speed up server login and network synchronization.
                   1172:   - Add support for up to 3 targets in WHOIS queries, also allow up to one
                   1173:     wildcard query from local hosts. Follows ircd 2.10 implementation rather
                   1174:     than RFC 2812. At most 10 entries are returned per wildcard expansion.
                   1175:   - ngircd.conf(5) manual page: describe types of configuration variables
                   1176:     (booleans, text strings, integer numbers) and add type information to each
                   1177:     variable description.
                   1178:   - Don't use "the.net" in sample-ngircd.conf, use "example.net".
                   1179:   - Terminate incoming connections on HTTP commands "GET" and "POST".
                   1180:   - New configuration option "CloakHost": when set, this host name is used for
                   1181:     every client instead of the real DNS host name (or IP address).
                   1182:   - New configuration option "CloakUserToNick": when enabled, ngIRCd sets
                   1183:     every clients' user name to their nickname and hides the user name
                   1184:     supplied by the IRC client.
                   1185:   - doc/Protocol.txt: Update description of the CHANINFO and WEBIRC commands.
                   1186:   - Doxygen'ify (document) much more source files; code cleanup ...
                   1187:   - Make write buffers bigger, but flush early. Before this change, a client
                   1188:     got disconnected if the buffer flushing at 4k failed, now regular clients
                   1189:     can store up to 32k and servers up 64k even if flushing is not possible at
                   1190:     the moment. This enhances reliability on slow links.
                   1191:   - Don't access possibly free'd CLIENT structure. Ooops.
                   1192:   - Allow "Port = 0" in [Server] blocks. Port number 0 marks remote servers
                   1193:     that try to connect to this daemon, but where this daemon never tries to
                   1194:     establish a connection on its own: only incoming connections are allowed.
                   1195:   - Configuration: fix 'Value of "..." is not a number!' for negative values.
                   1196:   - Enable WHOIS command to return information about services.
                   1197:   - Implement channel mode 'O': "IRC operators only". This channel mode is
                   1198:     used on DALnet (bahamut), for example.
                   1199:   - Remove support for ZeroConf/Bonjour/Rendezvous service registration
                   1200:     including the "[No]ZeroConf" configuration option.
                   1201:   - TOPIC command: test for channel admin rights correctly: this enables other
                   1202:     servers, services and IRC operators to change channel topics, even when
                   1203:     the client is not joined to this channel.
                   1204:   - Deprecate NoXX-Options in ngircd.conf and move new variants into our new
                   1205:     [Options] section: 'NoDNS=no' => 'DNS=yes', 'NoIdent=no' => 'Ident=yes',
                   1206:     'NoPAM=no' => 'PAM=yes', and 'NoZeroConf=no' => 'ZeroConf=yes' (and
                   1207:     vice-versa). The defaults are adjusted accordingly and the old variables
                   1208:     in [Global] are still accepted, so there is no functional change.
                   1209:   - Fix confusing "adding to invite list" debug messages: adding entries to
                   1210:     ban list produced 'invite list' debug output ...
                   1211:   - Don't throttle services and servers being registered.
                   1212:   - Xcode: correctly sort files :-)
                   1213:   - Don't assert() when searching a client for an invalid server token (this is
                   1214:     only relevant when a trusted server on a server-server link sends invalid
                   1215:     commands).

                   1218:
                   1219:   - --configtest: remember if MOTD is configured by file or phrase
                   1220:   - Enhance log messages when establishing server links a little bit
                   1221:   - Reset ID of outgoing server link on DNS error correctly
                   1222:   - Don't log critical (or worse) messages to stderr
                   1223:   - Manual page ngircd(8): add SIGNALS section
                   1224:   - Manual pages: update and simplify AUTHORS section
                   1225:   - Remove "error file" when compiled with debug code enabled
                   1226:   - README: Updated list of implemented commands
                   1227:   - add doc/README-Interix.txt and doc/Bopm.txt to distribution tarball
                   1228:   - Merge branch 'numeric-329'
                   1229:   - add doc/PAM.txt to distribution tarball
                   1230:   - New numeric 329: get channel creation time on "MODE #chan" commands
                   1231:   - Save channel creation time; new function Channel_CreationTime()

                   1236:   - Fix up generation and distribution of sample-ngircd.conf
                   1237:   - contrib/ngircd-redhat.init: updated email address of Naoya Nakazawa
                   1238:   - contrib/platformtest.sh: make command name quoting consistent
                   1239:
                   1240:   ngIRCd 17~rc3 (2010-10-27)
                   1241:   - Xcode builds: detect version number correctly, updated project file
                   1242:     to use the Mac OS X 10.5.x SDK, disable pam_fail_delay() because it
                   1243:     is only available starting with Mac OS X 10.6, and generate a default
                   1244:     PAM configuration for the Mac OS X Installer.app package of ngIRCd.
                   1245:   - Debian: updated standards version to 3.9.1, added libpam0g-dev to the
                   1246:     dependencies, and install a default /etc/pam.d/ngircd allowing all logins.
                   1247:   - Make contrib/platformtest.sh more portable.
                   1248:   - Fix connect attempts to further IP addresses of outgoing server links.

                   1251:   - ZeroConf: include header files missing since commit a988bbc86a.
                   1252:   - Generate ngIRCd version number from GIT tag.
                   1253:   - Make source code compatible with ansi2knr again. This allows to compile
                   1254:     ngIRCd using a pre-ANSI K&R C compiler again.
                   1255:   - ./configure: check if C compiler can compile ISO Standard C.
                   1256:   - ./configure: check support for C prototypes again.
                   1257:   - Don't use PARAMS() macro for function implementations.
                   1258:   - Added m68k/apple/aux3.0.1 (gcc 2.7.2) to doc/Platforms.txt.
                   1259:   - Only try to set FD_CLOEXEC if this flag is defined.
                   1260:   - Only use "__attribute__ ((unused))" if GCC >=2.8 is used.
                   1261:   - doc/Makefile.am: don't set docdir, automake handles it already.
                   1262:
                   1263:   ngIRCd 17~rc1 (2010-10-11)
                   1264:   - New configuration option "NoZeroConf" to disable service registration at
                   1265:     runtime even if ngIRCd is compiled with support for ZeroConf (e.g. using
                   1266:     Howl, Avahi or on Mac OS X).
                   1267:   - New configuration option "SyslogFacility" to define the syslog "facility"
                   1268:     (the "target"), to which ngIRCd should send its log messages.
                   1269:     Possible values are system dependent, but most probably "auth", "daemon",
                   1270:     "user" and "local1" through "local7" are possible values; see syslog(3).
                   1271:     Default is "local5" for historical reasons.
                   1272:   - Dump the "internal server state" (configured servers, established
                   1273:     connections and known clients) to the console or syslog when receiving
                   1274:     the SIGUSR2 signal and debug mode is enabled.
                   1275:   - Enable the daemon to disable and enable "debug mode" on runtime using
                   1276:     signal SIGUSR1, when debug code is compiled in, not only on startup
                   1277:     using the command line parameters.
                   1278:   - Signal handler: added new 'delayed' signal handlers, including fallback
                   1279:     to deprecated sysv API. And removed global NGIRCd_SignalRehash variable.
                   1280:   - IO: add io_cloexec() to set close-on-exec flag.
                   1281:   - ng_ipaddr.h: include required assert.h header.
                   1282:   - Conn_SyncServerStruct(): test all connections; and work case insensitive
                   1283:   - configure script: correctly indent IPv6 yes/no summary output.
                   1284:   - Don't reset My_Connections[Idx].lastping when reading data, so the
                   1285:     client lag debug-output is working again.
                   1286:   - Implement user mode "x": host name cloaking (closes: #102).
                   1287:   - Make configure switch "--docdir" work (closes: #108).
                   1288:   - Reformat and update FAQ.txt a little bit.
                   1289:   - INSTALL: mention SSL, IPv6, and changed handling of MotdFile.
                   1290:   - Change MOTD file handling: ngIRCd now caches the contents of the MOTD
                   1291:     file, so the daemon now requires a HUP signal or REHASH command to
                   1292:     re-read the MOTD file when its content changed.
                   1293:   - Startup: open /dev/null before chroot'ing the daemon.
                   1294:   - Allow IRC ops to change channel modes even without OperServerMode set.
                   1295:   - Allow IRC operators to use MODE command on any channel (closes: #100).
                   1296:   - Added mailmap file for git-[short]log and git-blame.
                   1297:   - Authenticated users should be registered without the "~" mark.
                   1298:   - Set NoPAM=yes in configuration files used for the testsuite.
                   1299:   - New configuration option "NoPAM" to disable PAM.
                   1300:   - Implement asynchronous user authentication using PAM, please see the
                   1301:     file doc/PAM.txt for details.
                   1302:   - Resolver: Implement signal handler and catch TERM signals.
                   1303:   - Don't set a penalty time when doing DNS lookups.
                   1304:   - Add some documentation for using BOPM with ngIRCd, see doc/Bopm.txt.
                   1305:   - Implement user mode "c": receive connect/disconnect NOTICEs. Note that
                   1306:     this new mode requires the user to be an IRC operator.
                   1307:   - ngircd.init: require "$network" and "$remote_fs" when stopping ngircd.
                   1308:   - Show SSL status in WHOIS output, numeric 275.
                   1309:   - Include correct header files when testing for arpa/inet.h (Closes: #105).
                   1310:   - Don't access already freed memory in IRC_KILL().
                   1311:   - Fix "beeing" typo ...
                   1312:   - SSL/TLS: fix bogus "socket closed" error message.

                   1321:   - Fix gcc warning "ignoring return value of ..."
                   1322:   - Include netinet/in_systm.h alongside netinet/ip.h
                   1323:   - Include netinet/{in.h, in_systm.h} when checking for netinet/ip.h
                   1324:   - Only include <netinet/in_systm.h> if it exists
                   1325:   - Updated doc/Platforms.txt
                   1326:   - Enhance connection statistics counters: display total number of served
                   1327:     connections on daemon shutdown and when a new client connects using
                   1328:     the new numeric RPL_STATSCONN (250).

                   1335:   - Updated links to the ngIRCd homepage (bug tracker, mailing list).
                   1336:   - Added missing modes to USERMODES #define
                   1337:   - Show our name (IRCD=ngIRCd) in ISUPPORT (005) numeric
                   1338:   - Quote received messages of ERROR commands in log output.
                   1339:   - ngircd.conf manual page: document missing "Password" variable.
                   1340:   - Implement WEBIRC command used by some Web-IRC frontends. The password
                   1341:     required to secure this command must be configured using the new
                   1342:     "WebircPassword" variable in the ngircd.conf file.

                   1351:     every channel, and c) remote clients using a server not supporting this
                   1352:     mode are not checked either and therefore always allowed to join.

                   1558:   - When using epoll() IO interface, compile in the select() interface as
                   1559:     well and fall back to it when epoll() isn't available on runtime.
                   1560:   - New configure option "--without-select" to disable select() IO API
                   1561:     (even when using epoll(), see above).
                   1562:   - Added support for IO APIs "poll()" and "/dev/poll".
                   1563:   - Reorganized internal handling of invite and ban lists.
                   1564:
                   1565: ngIRCd 0.10.1 (2006-12-17)
                   1566:
                   1567:   - Fixed validation of server names containing digits.
                   1568:   - Update the "info text" of the local server after re-reading configuration.
                   1569:   - Changed Numerics 265 and 266 to follow ircd 2.11.x "standards".
                   1570:   - Allow PASS syntax defined in RFC 1459 for server links, too.
                   1571:   - Enhanced ISUPPORT message (005 numeric).
                   1572:   - New configuration option "PredefChannelsOnly": if set, clients can only
                   1573:     join predefined channels.
                   1574:   - Code cleanups: use "LogDebug(...)" instead of "Log(LOG_DEBUG, ...)", use
                   1575:     "strcspn()", unsigned vs. signed, use "const", fix whitespaces, ...
                   1576:
                   1577: ngIRCd 0.10.0 (2006-10-01)
                   1578:
                   1579:   - Fixed file handle leak when daemon is not able to send MOTD to a client.
                   1580:
                   1581:   ngIRCd 0.10.0-pre2 (2006-09-09)
                   1582:   - Fixed build problems with GCC option -fstack-protector.
                   1583:   - Minor documentation updates.
                   1584:
                   1585:   ngIRCd 0.10.0-pre1 (2006-08-02)
                   1586:   - Validate "ServerName" (see RFC 2812, section 2.3.1).
                   1587:   - Enhanced DIE to accept a single parameter ("comment text") which is sent
                   1588:     to all locally connected clients before the server goes down.
                   1589:   - The ngIRCd handles time shifts backwards more gracefully now (the
                   1590:     timeout handling doesn't disconnect clients by mistake any more).
                   1591:   - Internal: Restructured connection handling (the connection ID is equal
                   1592:     to the file descriptor of the connection).
                   1593:   - Internal: Simplified resolver code.
                   1594:   - JOIN now supports more than one channel key at a time.
                   1595:   - Implemented numeric "333": Time and user name who set a channel topic.
                   1596:   - Enhanced the handler for PING and PONG commands: fix forwarding and enable
                   1597:     back-passing of a client supplied additional argument of PING.
                   1598:   - Changed handling of timeouts for unregistered connections: don't reset
                   1599:     the counter if data is received and disconnect clients earlier.
                   1600:   - Removed unnecessary #define of "LOCAL", now use plain C "static" instead.
                   1601:   - Channel topics are no longer limited to 127 characters: now the only limit
                   1602:     is the maximum length of an IRC command, i. e. 512 bytes (in practice, this
                   1603:     limits the topic to about 490 characters due to protocol overhead).
                   1604:   - Reverse DNS lookup code now checks the result by doing an additional
                   1605:     lookup to prevent spoofing.
                   1606:   - Added new IO layer which (optionally) supports epoll() and kqueue() in
                   1607:     addition to the select() interface.
                   1608:
                   1609: ngIRCd 0.9.2 (2005-10-15)
                   1610:
                   1611:   - Fixed a bug that could cause the daemon to crash when outgoing server
                   1612:     connections can't be established.
                   1613:   - Fixed a bug that caused the daemon to leak file descriptors when no
                   1614:     resolver subprocesses could be created.
                   1615:   - Fixed server NOTICEs to users with "s" mode ("server messages").
                   1616:   - Fixed a format string bug in "connection statistics" messages to clients.
                   1617:
                   1618: ngIRCd 0.9.1 (2005-08-03)
                   1619:
                   1620:   - The KILL command killed much more than desired (including server links!)
                   1621:     when the target user is connected to a remote server. Bug introduced in
                   1622:     ngIRCd 0.9.0 ...  Reported by <qssl@fastmail.fm>, Thanks!
                   1623:   - Changed some constants to be "signed" (instead of unsigned) to solve
                   1624:     problems with old (pre-ANSI) compilers.
                   1625:
                   1626: ngIRCd 0.9.0 (2005-07-24)
                   1627:
                   1628:   ngIRCd 0.9.0-pre1 (2005-07-09)
                   1629:   - Fixed maximum length of user names, now allow up to 9 characters.
                   1630:   - Cut off oversized IRC messages that should be sent to the network instead
                   1631:     of shutting down the (wrong) connection.
                   1632:   - Don't generate error messages for unknown commands received before the
                   1633:     client is registered with the server (like the original ircd).
                   1634:   - Never run with root privileges but always switch the user ID.
                   1635:   - Make "netsplit" messages RFC compliant.
                   1636:   - Fix handling of QUIT Messages: send only one message, even if the client
                   1637:     is member of multiple channels.
                   1638:   - Don't exit server if closing of a socket fails; instead ignore it and
                   1639:     pray that this will be "the right thing" ...
                   1640:   - Implemented the IRC function "WHOWAS".
                   1641:   - Don't enable assert() calls when not ./configure'd with --enable-debug.
                   1642:   - Fixed ./configure test for TCP Wrappers: now it runs on Mac OS X as well.
                   1643:   - Enhanced configure script: now you can pass an (optional) search path
                   1644:     to all --with-XXX parameters, e. g. "--with-ident=/opt/ident".
                   1645:   - Removed typedefs for the native C data types.
                   1646:     Use stdbool.h / inttypes.h if available.
                   1647:   - New configuration option "OperServerMode" to enable a workaround needed
                   1648:     when running an network with ircd2 servers and "OperCanUseMode" enabled
                   1649:     to prevent the ircd2 daemon to drop mode changes of IRC operators.
                   1650:     Patch by Florian Westphal, <westphal@foo.fh-furtwangen.de>.
                   1651:   - Implemented support for "secret channels" (channel mode "s").
                   1652:   - New configuration option "Mask" for [Operator] sections to limit OPER
                   1653:     commands to users with a specific IRC mask. Patch from Florian Westphal.
                   1654:   - Write "error file" (/tmp/ngircd-XXX.err) only if compiled with debug
                   1655:     code ("--enable-debug") and running as daemon process.
                   1656:   - Don't create version information string each time a client connects
                   1657:     but instead on server startup. By Florian Westphal.
                   1658:   - New configuration variable "PidFile", section "[Global]": if defined,
                   1659:     the server writes its process ID (PID) to this file. Default: off.
                   1660:     Idea of Florian Westphal, <westphal@foo.fh-furtwangen.de>.
                   1661:   - Code cleanups from Florian Westphal, <westphal@foo.fh-furtwangen.de>.
                   1662:   - Raised the maximum length of passwords to 20 characters.
                   1663:   - Fixed a memory leak when resizing the connection pool and realloc()
                   1664:     failed. Now we don't fall back to malloc(), which should be sane anyway.
                   1665:     Patch from Florian Westphal, <westphal@foo.fh-furtwangen.de>.
                   1666:   - Added support for the Howl (http://www.porchdogsoft.com/products/howl/)
                   1667:     Rendezvous API, in addition to the API of Apple (Mac OS X). The available
                   1668:     API will be autodetected when you call "./configure --with-rendezvous".
                   1669:   - Made ngIRCd compile on HP/UX 10.20 with native HP pre-ANSI C compiler and
                   1670:     most probably other older C compilers on other systems.
                   1671:   - When the daemon should switch to another user ID (ServerID is defined in
                   1672:     the configuration file) and is not running in a chroot environment, it
                   1673:     changes its working directory to the home directory of this user. This
                   1674:     should enable the system to write proper core files when not running with
                   1675:     root privileges ...
                   1676:
                   1677: ngIRCd 0.8.3 (2005-02-03)
                   1678:
                   1679:   - Fixed a bug that could case a root exploit when the daemon is compiled
                   1680:     to do IDENT lookups and is logging to syslog. Bug discovered by CoKi,
                   1681:     <coki@nosystem.com.ar>, thanks a lot!
                   1682:     (CVE-2005-0226; http://www.nosystem.com.ar/advisories/advisory-11.txt)
                   1683:
                   1684: ngIRCd 0.8.2 (2005-01-26)
                   1685:
                   1686:   - Added doc/SSL.txt to distribution.
                   1687:   - Fixed a buffer overflow that could cause the daemon to crash. Bug found
                   1688:     by Florian Westphal, <westphal@foo.fh-furtwangen.de>. (CVE-2005-0199)
                   1689:   - Fixed a possible buffer underrun when reading the MOTD file. Thanks
                   1690:     to Florian Westphal, <westphal@foo.fh-furtwangen.de>.
                   1691:   - Fixed detection of IRC lines which are too long to send. Detected by
                   1692:     Florian Westphal, <westphal@foo.fh-furtwangen.de>.
                   1693:   - Fixed return values of our own implementation of strlcpy(). The code has
                   1694:     been taken from rsync and they fixed it, but we didn't until today :-/
                   1695:     It has only been used when the system didn't implement strlcpy by itself,
                   1696:     not on "modern" systems. Florian Westphal, <westphal@foo.fh-furtwangen.de>.
                   1697:
                   1698: ngIRCd 0.8.1 (2004-12-25)
                   1699:
                   1700:   - Autoconf: Updated config.guess and config.sub
                   1701:   - Added some more debug code ...
                   1702:   - Fixed wrong variable names in output of "ngircd --configtest".
                   1703:   - Debian: Fixed the name of the "default file" in the init script for
                   1704:     ngircd-full packages. And do the test if the binary is executable after
                   1705:     reading this file.
                   1706:   - Enhanced the "test suite": please have a look at src/testsuite/README!
                   1707:
                   1708: ngIRCd 0.8.0 (2004-06-26)
                   1709:
                   1710:   - Fixed wrong buffer size calculation for results of the resolver.
                   1711:
                   1712:   ngircd 0.8.0-pre2 (2004-05-16)
                   1713:   - Enhanced logging to console when running in "no-detached mode": added
                   1714:     PID and log messages of resolver sub-processes.
                   1715:   - Fixed host name lookups when using IDENT user lookups.
                   1716:   - "make clean" and "make maintainer-clean" remove more files now.
                   1717:
                   1718:   ngIRCd 0.8.0-pre1 (2004-05-07)
                   1719:   - Two new configuration options: "ChrootDir" and "MotdPhrase", thanks to
                   1720:     Benjamin Pineau <ben@zouh.org>. Now you can force the daemon to change
                   1721:     its root and working directory to something "safe". MotdPhrase is used
                   1722:     to define an "MOTD string" instead of a whole file, useful if the
                   1723:     "real" MOTD file would be outside the "jail".
                   1724:   - INVITE- and BAN-lists become synchronized between IRC+ servers when
                   1725:     establishing new connections, if the peer supports this as well.
                   1726:   - Reorganized autogen.sh and configure scripts.
                   1727:   - Fixed a wrong assert() which could cause the daemon to exit spuriously
                   1728:     when closing down connections.
                   1729:   - Better logging of decompression errors returned by zlib.
                   1730:   - Servers other than the destination server didn't clean up the invite
                   1731:     list of an "invite-only" channel properly when an INVITE'd user joined.
                   1732:   - Changed the reply of the MODE command to match the syntax of the
                   1733:     original ircd exactly: the unnecessary but missing ":" before the last
                   1734:     parameter has been added.
                   1735:   - Fixed TRACE: don't output "Serv" lines for ourself; display more info.
                   1736:   - Results of the resolver (host names and IDENT names) are discarded after
                   1737:     the client is successfully registered with the server.
                   1738:   - Better logging while establishing and shutting down connections.
                   1739:   - The type of service (TOS) of all sockets is set to "interactive" now.
                   1740:   - Added short command line option "-t" as alternative to "--configtest".
                   1741:   - Added optional support for "IDENT" lookups on incoming connections. You
                   1742:     have to enable this function with the ./configure switch "--with-ident".
                   1743:     The default is not to do IDENT lookups.
                   1744:
                   1745: ngIRCd 0.7.7 (2004-02-05)
                   1746:
                   1747:   - The info text ("real name") of users is set to "-" if none has been
                   1748:     specified using the USER command (e. g. "USER user * * :"). Reason:
                   1749:     the original ircd doesn't like empty ones and would KILL such users.
                   1750:   - Fixed (optional) TCP Wrapper test which was broken and could result in
                   1751:     false results. Thanks to Fuminori Tanizaki <tany@mcnet.ad.jp>!
                   1752:   - Removed "USE_" prefixes of configuration #defines.
                   1753:
                   1754: ngIRCd 0.7.6 (2003-12-05)
                   1755:
                   1756:   - Fixed abort() ("server crash") when INVITE'ing users to nonexistent
                   1757:     channels. Bug found by <hiddenx@wp.pl>.
                   1758:   - Extended version numbering of CVS versions (added date).
                   1759:   - Enhanced/fixed doc/Protocol.txt;
                   1760:
                   1761: ngIRCd 0.7.5 (2003-11-07)
                   1762:
                   1763:   - Fixed ban behavior: users which are banned from a channel can't no
                   1764:     longer send PRIVMSG's to this channel (fixes Bug #47).
                   1765:   - Fixed and enhanced the "penalty handling" of the server: commands that
                   1766:     require more resources block the client for a short time.
                   1767:   - Changed the internal time resolution to one second.
                   1768:   - New configuration variable "MaxConnectionsIP" to limit the number of
                   1769:     simultaneous connections from a single IP that the server will accept.
                   1770:     This configuration options lowers the risk of denial of service attacks
                   1771:     (DoS), the default is 5 connections per client IP.
                   1772:   - Fixed build problems under Mac OS X 10.3.
                   1773:   - Use "-pipe" when compiling with gcc, speeds things up a little :-)
                   1774:   - Added new configuration variable "Listen" to bind all listening
                   1775:     sockets of the server to a single IP address.
                   1776:   - Suppress misleading error message of diff during make run.
                   1777:   - Enhanced test-suite and made it work on GNU/Hurd.
                   1778:   - Fixed minor typo in debug output :-)
                   1779:
                   1780: ngIRCd 0.7.1 (2003-07-18)
                   1781:
                   1782:   - Included files to build Debian packages (located in "debian/").
                   1783:   - Updated config.guess and config.sub to newer upstream versions.
                   1784:   - NJOIN propagates user channel modes correctly again ... Upsa.
                   1785:   - Made Makefile more compatible with "make -j<n>".
                   1786:   - Added support for GNU/Hurd.
                   1787:   - Fixed a compiler warning related to an unnecessary assert().
                   1788:   - Enhanced VERSION command when using debug versions.
                   1789:
                   1790: ngIRCd 0.7.0 (2003-05-01)
                   1791:
                   1792:   - "ServerName" is checked better now: a dot (".") is required.
                   1793:   - The KILL command verifies and logs more parameters.
                   1794:
                   1795:   ngIRCd 0.7.0-pre2 (2003-04-27)
                   1796:   - CVS build system fixes (made autogen.sh more portable).
                   1797:   - Fixed compilation and test-suite on Solaris (tested with 2.6).
                   1798:   - New documentation file "doc/Platforms.txt" describing the status of
                   1799:     ngIRCd on the various tested platforms.
                   1800:   - Test for broken GCC on Mac OS X and disable "-pedantic" in this case.
                   1801:   - Disable "-ansi" on Cygwin: system headers are incompatible.
                   1802:   - The server tried to connect to other servers only once when DNS or
                   1803:     socket failures occurred.
                   1804:   - Fixed --configtest: There is no variable "ServerPwd", it's "Password".
                   1805:
                   1806:   ngIRCd 0.7.0-pre1 (2003-04-22)
                   1807:   - New signal handler (more secure, actions are executed outside).
                   1808:   - GCC: the compiler is now called with more warning options enabled.
                   1809:   - Replaced a lot of str[n]cpy(), str[n]cat() and sprintf() calls with the
                   1810:     more secure functions strlcpy(), strlcat() and snprintf(). On systems
                   1811:     that don't support strlcpy() and strlcat(), these functions are included
                   1812:     in the libngportab now (with prototypes in portab.h).
                   1813:   - If the server can't close a socket, it panics now. This is an error that
                   1814:     can't occur during normal operation so there is something broken.
                   1815:   - The order of log messages during disconnects is more "natural" now ;-)
                   1816:   - Cleaned up handling of server configuration structures: modifying and
                   1817:     removing servers during runtime works more reliable now.
                   1818:   - Compression code from "conn.[ch]" is now found in new "conn-zip.[ch]"
                   1819:   - Moved some connection functions from "conn.[ch]" to "conn-func.[ch]".
                   1820:   - New command CONNECT to enable and add server links. The syntax is not
                   1821:     RFC-compatible: use "CONNECT <name> <port>" to enable and connect an
                   1822:     configured server and "CONNECT <name> <port> <host> <mypwd> <peerpwd>"
                   1823:     to add a new server (ngIRCd tries to connect new servers only once!).
                   1824:   - Added DISCONNECT command ("DISCONNECT <name>") to disable servers.
                   1825:   - Restructured the documentation: Now the main language is English. The
                   1826:     German documentation has been removed (until there is a maintainer).
                   1827:   - Enhanced killing of users caused by a nickname collision.
                   1828:   - Better error detection for status code ("numerics") forwarding.
                   1829:   - Moved tool functions to own library: "libngtool".
                   1830:   - New command TRACE (you can trace only servers at the moment).
                   1831:   - New command HELP that lists all understood commands.
                   1832:   - There should no longer remain "unknown connections" (see e.g. LUSERS)
                   1833:     if an outgoing server link can't be established.
                   1834:   - Added AC_PREREQ(2.50) to configure.in for better autoconf compatibility.
                   1835:   - Conn_Close() now handles recursive calls for the same link correctly.
                   1836:   - ngIRCd can register itself with Rendezvous: to enable support pass the
                   1837:     new switch "--with-rendezvous" to configure.
                   1838:   - Added support for TCP Wrappers library: pass "--with-tcp-wrappers" to
                   1839:     configure to enable it.
                   1840:   - Changed some configure options to use "--with"/"--without" as prefix
                   1841:     instead of "--enable"/"--disable": "--without-syslog", "--without-zlib",
                   1842:     "--with-tcp-wrappers", and "--with-rendezvous".
                   1843:   - Better error reporting to clients on connect.
                   1844:   - Enhanced manual pages ngircd(8) and ngircd.conf(5).
                   1845:   - Documentation is now installed in $(datadir)/doc/ngircd.
                   1846:   - Enhanced handling of NJOIN in case of nick collisions.
                   1847:
                   1848: ngIRCd 0.6.1 (2003-01-21)
                   1849:
                   1850:   - Fixed KILL: you can't crash the server by killing yourself any more,
                   1851:     ngIRCd no longer sends a QUIT to other servers after the KILL, and you
                   1852:     can kill only valid users now.
                   1853:   - The server no longer forwards commands to ordinary users, instead it
                   1854:     answers with the correct error message ("no such server") now.
                   1855:   - WHOIS commands weren't always forwarded as requested.
                   1856:   - The server sets a correct default AWAY message now when propagating
                   1857:     between servers (bug introduced in 0.6.0).
                   1858:   - Fixed up and enhanced CHANINFO command: channel keys and user limits
                   1859:     are synchronized between servers now, too.
                   1860:   - MODE returns the key and user limit for channel members correctly now.
                   1861:   - Non-members of a channel could crash the server when trying to change
                   1862:     its modes or modes of its members.
                   1863:   - The server didn't validate weather a target user is a valid channel
                   1864:     member when changing his channel user modes which could crash ngIRCd.
                   1865:
                   1866:
                   1867: Older changes (sorry, only available in German language):
                   1868:
                   1869: ngIRCd 0.6.0, 24.12.2002
                   1870:
                   1871:   ngIRCd 0.6.0-pre2, 23.12.2002
                   1872:   - neuer Numeric 005 ("Features") beim Connect.
                   1873:   - LUSERS erweitert: nun wird die maximale Anzahl der lokalen und globalen
                   1874:     Clients, die dem Server bzw. im Netzwerk seit dem letzten (Re-)Start
                   1875:     dem Server gleichzeitig bekannt waren, angezeigt.
                   1876:
                   1877:   ngIRCd 0.6.0-pre1, 18.12.2002
                   1878:   - beim Schliessen einer Verbindung zeigt der Server nun vor dem ERROR
                   1879:     noch eine Statistik ueber die empfangene und gesendete Datenmenge an.
                   1880:   - der Server wartet bei einer eingehenden Verbindung nun laenger auf den
                   1881:     Resolver (4 Sekunden), wenn das Ergebnis eintrifft setzt er aber den
                   1882:     Login sofort fort (bisher wurde immer mind. 1 Sekunde gewartet).
                   1883:   - Connection-Strukturen werden nun "pool-weise" verwaltet; der Pool wird
                   1884:     bei Bedarf bis zu einem konfigurierten Limit vergroessert.
                   1885:   - Mit der neuen Konfigurationsvariable "MaxConnections" (Sektion "Global")
                   1886:     kann die maximale Anzahl gleichzeitiger Verbindungen begrenzt werden.
                   1887:     Der Default ist -1, "unlimitiert".
                   1888:   - der Server erkennt nun, ob bereits eine eingehende Verbindung von einem
                   1889:     Peer-Server besteht und versucht dann nicht mehr, selber eine eigene
                   1890:     ausgehende Verbindung zu diesem auufzubauen. Dadurch kann nun auf beiden
                   1891:     Servern in der Konfiguration ein Port fuer den Connect konfiguriert
                   1892:     werden (beide Server versuchen sich dann gegenseitig zu connectieren).
                   1893:   - Test-Suite und Dokumentation an A/UX angepasst.
                   1894:   - unter HP-UX definiert das configure-Script nun _XOPEN_SOURCE_EXTENDED.
                   1895:   - Server identifizieren sich nun mit asynchronen Passwoertern, d.h. das
                   1896:     Passwort, welches A an B schickt, kann ein anderes sein als das, welches
                   1897:     B als Antwort an A sendet. In der Konfig.-Datei, Abschnitt "Server",
                   1898:     wurde "Password" dazu durch "MyPassword" und "PeerPassword" ersetzt.
                   1899:   - Der Server kann nun zur Laufzeit die Konfiguration neu einlesen: dies
                   1900:     macht er nach dem Befehl REHASH oder wenn ein HUP-Signal empfangen wird.
                   1901:   - Channel-Mode "P" ("persistent") kann nur noch von IRC-Operatoren gesetzt
                   1902:     werden. Grund: User koennen den Server sonst leicht "Channel-Flooden".
                   1903:   - MOTD kann nun an andere Server geforwarded werden.
                   1904:   - IRC-Befehl "TIME" implementiert.
                   1905:   - Server-Server-Links koennen nun komprimiert werden, dazu wird die zlib
                   1906:     (www.zlib.org) benoetigt. Unterstuetzt die Gegenseite die Komprimierung
                   1907:     nicht, wird automatisch unkomprimiert kommuniziert. Das Verfahren ist
                   1908:     kompatibel mit dem Original-ircd 2.10.3, d.h. beide Server koennen
                   1909:     miteinander ueber komprimiert Links kommunizieren.
                   1910:   - Handling der Schreibpuffer umgestellt: Server sollte schneller arbeiten.
                   1911:   - Prefix-Fehler werden besser protokolliert (mit verursachendem Befehl).
                   1912:   - SQUIT wird nicht mehr doppelt an andere Server weitergeleitet.
                   1913:   - Der Server versucht nun vor dem Schliessen einer Verbindung Daten, die
                   1914:     noch im Schreibpuffer stehen, zu senden.
                   1915:   - Source in weiteres Modul "irc-info" aufgespalten.
                   1916:   - Konfigurationsvariablen werden besser validiert: Laengen, Zahlen, ...
                   1917:   - neuen Befehl STATS begonnen: bisher unterstuetzt wird "l" und "m".
                   1918:   - bei ISON und USERHOST fehlte im Ergebnis-String der korrekte Absender.
                   1919:   - IRC Operatoren koennen nun mit KILL User toeten. Achtung: ein Grund muss
                   1920:     zwingend als zweiter Parameter angegeben werden!
                   1921:   - neue Konfigurations-Variable "MaxJoins": Hiermit kann die maximale Zahl
                   1922:     der Channels, in denen ein User Mitglied sein kann, begrent werden.
                   1923:   - neuer, deutlich flexiblerer Parser fuer den MODE Befehl.
                   1924:   - neue Channel-Modes l (User-Limit) und k (Channel-Key) implementiert.
                   1925:
                   1926: ngIRCd 0.5.4, 24.11.2002
                   1927:
                   1928:   - Fehler-Handling von connect() gefixed: der Server kann sich nun auch
                   1929:     unter A/UX wieder zu anderen verbinden.
                   1930:   - in den Konfigurationsvariablen ServerUID und ServerGID kann nun nicht
                   1931:     nur die numerische ID, sondern auch der Name des Users bzw. der Gruppe
                   1932:     verwendet werden. Beim Start des Daemons wird nun beides angezeigt.
                   1933:   - Besseres Logging von Prefix-Fehlern.
                   1934:   - angenommene Sockets werden nun korrekt auf "non-blocking" konfiguriert,
                   1935:     beim Senden und Empfangen werden Blockierungen besser abgefangen.
                   1936:   - RPL_UMODEIS hat Code 221, nicht 211 ... *argl*
                   1937:   - select() in Try_Write() hat falschen (keinen!) Timeout verwendet;
                   1938:     die "Zeit-Aufloesung" des Servers sind zudem nun 2 Sekunden (TIME_RES).
                   1939:     Insgesamt sollte die Reaktionszeit des Server nun besser sein.
                   1940:
                   1941: ngIRCd 0.5.3, 08.11.2002
                   1942:
                   1943:   - NOTICE liefert nun wirklich nie mehr einen Fehler, auch dann nicht,
                   1944:     wenn der sendende Client noch gar nicht registriert ist.
                   1945:   - ein "schneller Server-Reconnect" wird nur noch dann versucht, wenn die
                   1946:     Verbindung zuvor ordentlich (="lange genug") in Ordnung war; somit also
                   1947:     nicht meht, wenn der Peer-Server gleich beim Connect ein ERROR liefert.
                   1948:     Das vermeidet "Connect-Orgien".
                   1949:   - einige Datentypen aufgeraumt: z.B. sind viele INT32s nun LONGs. Das ist
                   1950:     auf Platformen mit 8-Byte-Integern kompatibler.
                   1951:   - RPL_YOURHOST_MSG ist nun ircII- und RFC-kompatibel ;-)
                   1952:   - Segfault unter hoher Netzaktivitaet behoben: in Conn_Close() wird die
                   1953:     Connection-Struktur nun frueher als "ungueltig" markiert.
                   1954:
                   1955: ngIRCd 0.5.2, 04.10.2002
                   1956:
                   1957:   - Buffer Overflow in Read_Resolver_Result() behoben.
                   1958:   - Format-String-Bugs, die zum Abbruch des Servers fuehrten, behoben.
                   1959:   - Maximale Laenge eines IRC-Prefix wurde falsch berechnet.
                   1960:
                   1961: ngIRCd 0.5.1, 03.10.2002
                   1962:
                   1963:   - in RPL_YOURHOST_MSG wurde ein fehlerhafter Versionsstring geliefert.
                   1964:   - Test-Suite: start-server.sh, stop-server.sh und stress-server.sh koennen
                   1965:     nun "manuell" von der Kommandozeile gestartet werden, stress-server.sh
                   1966:     startet per Default nur noch 5 Sessions, eine andere Zahl kann auf der
                   1967:     Kommandozeile uebergeben werden (Syntax: "stress-server.sh <count>").
                   1968:   - In bestimmten Faellen hat der Server versucht auf einen bereits wieder
                   1969:     geschlossenen Socket Daten zu schreiben; das fuehrte zu einem Abbruch des
                   1970:     Servers durch ein assert(). Nun wird geprueft, ob der Socket noch ok ist.
                   1971:   - im "contrib"-Verzeichnis befindet sich nun eine RPM-Spec-Datei, aus den
                   1972:     .tar.gz's koennen nun mit "rpm -ta <archiv>" RPM's erzeugt werden. Danke
                   1973:     an Sean Reifschneider <jafo@tummy.com>!
                   1974:   - Syntax von RPL_MYINFO_MSG korrigiert: liefert nun vier Parameter.
                   1975:
                   1976: ngIRCd 0.5.0, 20.09.2002
                   1977:
                   1978:   - Dokumentation aktualisiert.
                   1979:   - Fehler bei Validierung von "AdminInfo2" behoben.
                   1980:   - Test der Flags fuer "ps" in der Testsuite verbessert, ist nun zu mehr
                   1981:     Plattformen kompatibler.
                   1982:
                   1983:   ngIRCd 0.5.0-pre2, 17.09.2002
                   1984:   - Fix in IRC_WriteStrServersPrefix() war "badly broken" -- behoben.
                   1985:
                   1986:   ngIRCd 0.5.0-pre1, 16.09.2002
                   1987:   - Manual-Pages ngircd.8 und ngircd.conf.5 begonnen.
                   1988:   - Wird der Netzwerk-Sniffer aktiviert (--sniffer), so schaltet der
                   1989:     ngIRCd nun automatisch in den Debug-Modus.
                   1990:   - auf Systemen, die inet_aton() nicht kennen (wie z.B. A/UX), kann der
                   1991:     ngIRCd nun dennoch auch aktiv Server-Links aufbauen.
                   1992:   - h_errno wird auf Systemen, die das nicht kennen (wie z.B. HP-UX 10.20)
                   1993:     nicht mehr verwendet. Somit compiliert der ngIRCd nun auch dort :-)
                   1994:   - um auf dem Ziel-System nicht vorhandene Funktionen nachzubilden wird nun
                   1995:     die "libngportab" erzeugt; genutzt wird dies bisher fuer vsnprintf().
                   1996:     Nun compiliert der ngIRCd auch unter Solaris 2.5.1.
                   1997:   - "persistente Channels" (Mode 'P') implementiert: diese koennen in der
                   1998:     Konfigurationsdatei definiert werden (Sektion "Channel", vgl. Beispiel-
                   1999:     Konfiguration "sample-ngircd.conf") und bleiben auch dann bestehen,
                   2000:     wenn kein User mehr im Channel ist. Zu Channel-Operatoren werden bisher
                   2001:     nur IRC-Operatoren, die den Channel betreten. Die persistenten Channels
                   2002:     werden durch das Flag "P" gelennzeichnet, welches normal durch Channel-
                   2003:     Op's gesetzt und geloescht werden kann.
                   2004:   - bei "--configtest" werden keine leere Abschnitte mehr ausgegeben.
                   2005:   - Source in weitere Module aufgespalten: lists, irc-op und resolve.
                   2006:   - #include's aufgeraeumt: Header includieren keine anderen mehr.
                   2007:   - KICK implementiert (bisher kann nur ein User aus einem Channel geckicked
                   2008:     werden, Listen, wir im RFC vorgesehen, werden bisher nicht unterstuetzt).
                   2009:   - INVITE, den Channel-Mode "i" sowie Invite-Lists ueber den MODE-Befehl
                   2010:     (setzen, erfragen und loeschen) implementiert.
                   2011:   - Source an ansi2knr fuer pre-ANSI-Compiler angepasst; ansi2knr in Source-
                   2012:     Tree aufgenommen und in Build-System integriert; der ngIRCd compiliert
                   2013:     nun z.B. unter A/UX mit dem nativen Compiler von Apple.
                   2014:   - TOPIC lieferte bei unbekanntem Channel einen falschen Fehlercode.
                   2015:   - LIST versteht nun Wildcards und kann an andere Server geforwarded werden.
                   2016:   - wurde ein KILL fuer nicht-lokale Clients empfangen, so wurden die
                   2017:     Verwaltungs-Strukturen nicht korrekt freigegeben.
                   2018:   - empfangene NJOIN's wurden "zerhackt" an andere Server weitergegeben.
                   2019:   - neue Konfigurationsoption "OperCanUseMode" (Sektion "Global"):
                   2020:     ist sie aktiv, koennen IRC-Operatoren immer Channel-Modes setzen.
                   2021:   - Dokumentation des neuen IRC+-Protokolls begonnen: doc/Protocol.txt
                   2022:   - Protokoll- und Server-ID bei PASS-Befehlen auf neues Format umgestellt;
                   2023:     bei empfangenen PASS-Befehlen werden diese zudem nun auch ausgewertet.
                   2024:     Die unterstuetzten Flags sind in doc/Protocol.txt beschrieben.
                   2025:   - mit dem neuen Befehl CHANINFO synchronisieren Server, die das IRC+-
                   2026:     Protokoll unterstuetzen, Channel-Modes und Topics.
                   2027:   - neue Option "--disable-ircplus" fuer das configure-Script, um das
                   2028:     IRC+-Protokoll abzuschalten (per Default ist es aktiviert).
                   2029:   - Ban-Lists (setzen, erfragen und loeschen) implementiert.
                   2030:   - wird der Server mit "-n"/"--nodaemon" gestartet, so werden keine Mel-
                   2031:     dungen mehr ueber Syslog ausgegeben, sondern nur noch auf der Konsole.
                   2032:   - "Test-Suite" begonnen (in "make check" integriert): Dabei wird ein
                   2033:     speziell konfigurierter Server auf Port 6789 gestartet, mit dem dann
                   2034:     einige Tests durchgefuehrt werden (u.a. "Stress-Test" mit 50 Clients).
                   2035:   - zu lange Operator-Namen in der Konfiguration wurden falsch gekuerzt.
                   2036:   - kleine Anpassung an AIX 3.2.5: nun laeuft der ngIRCd auch dort :-)
                   2037:   - ADMIN-Befehl implementiert. Die Daten hierzu werden in der Konfig-Datei
                   2038:     im [Global]-Abschnitt mit den Variablen "AdminInfo1", "AdminInfo2" und
                   2039:     "AdminEMail" konfiguriert.
                   2040:
                   2041: ngIRCd 0.4.3, 11.06.2002
                   2042:
                   2043:   - Bei PRIVMSG und NOTICE hat der ngIRCd nicht ueberpruft, ob das Ziel
                   2044:     ueberhaupt ein User ist. War es keiner, so fuehrte dies zu einem
                   2045:     Abbruch des Servers [es wurde assert() aufgerufen].
                   2046:
                   2047: ngIRCd 0.4.2, 29.04.2002
                   2048:
                   2049:   - LUSERS verzaehlt sich bei eigenen Server-Links nicht mehr.
                   2050:   - QUIT wird nun auch von noch nicht registrierten Clients akzeptiert.
                   2051:   - IRC-Funktion LIST implementiert; bisher werden allerdings noch keine
                   2052:     Wildcards (bis auf "*") unterstuetzt.
                   2053:
                   2054: ngIRCd 0.4.1, 08.04.2002
                   2055:
                   2056:   - Bei Server-Links wird nicht mehr an Hand der Anzahl der Parameter
                   2057:     eines empfangenen SERVER-Befehls, sondern "intern" erkannt, ob es
                   2058:     sich um eine ein- oder ausgehende Verbindung handelt und somit das
                   2059:     eigene PASS-SERVER-Paar gesendet werden muss oder nicht. Da sich
                   2060:     verschiedene Versionen des Original-ircd's anders verhalten, schlug
                   2061:     die Anmeldung je nach Gehenseite evtl. fehl.
                   2062:   - Bei einem NICK-Befehl eines lokalen Client konnte der Server ab-
                   2063:     stuerzen, da ein Format-String einer Log-Meldung fehlerhaft war.
                   2064:
                   2065: ngIRCd 0.4.0, 01.04.2002
                   2066:
                   2067:   - IRC-Befehle nochmal auf weitere Source-Dateien aufgespalten.
                   2068:   - WHO implementiert (bisher ohne komplette Unterstuetzung von Masks).
                   2069:   - Der AWAY-Mode wurde nicht ueber mehrere Server-Links weitergegeben.
                   2070:   - stderr wird nun in eine Datei umgelenkt (/tmp/ngircd-<PID>.err).
                   2071:     Laeuft der Server nicht im Debug-Modus, so wird diese bei Programm-
                   2072:     ende geloescht. Sollte der Server abstuerzen, finden sich hier evtl.
                   2073:     zusaetzliche Informationen.
                   2074:   - In Nicknames wird das Zeichen "-" nun als zulaessig erkannt.
                   2075:   - die Beispiel-Konfigurationsdatei (doc/sample-ngircd.conf) wird als
                   2076:     ngircd.conf installiert, wenn noch keine "echte" Konfigurationsdatei
                   2077:     vorhanden ist.
                   2078:   - bei WHO, WHOIS und NAMES wird nun nur noch der Status "Operator" oder
                   2079:     "voiced" geliefert -- nicht mehr beides.
                   2080:   - Server-Gruppen implementiert: es wird immer nur zu einem Server in
                   2081:     einer Gruppe eine Verbindung aufgebaut, klappt es beim ersten Server
                   2082:     nicht, so wird der naechste probiert (Variable "Group" in der Kon-
                   2083:     figurationsdatei, Sektion [Server]).
                   2084:   - IRC_PING() ist, wenn nicht im "strict RFC"-Mode, toleranter und ak-
                   2085:     zeptiert beliebig viele Parameter (z.B. BitchX sendet soetwas).
                   2086:   - die "Portab-Header" werden nicht mehr benoetigt, die System-Erkennung
                   2087:     wird nun ausschliesslich vom configure-Script durchgefuehrt. System-
                   2088:     abhaengige Definitionen finden sich nun unter src/portrab/.
                   2089:   - Clients und Channels werden nicht mehr ueber ihren Namen, sondern
                   2090:     einen Hash-Wert gesucht: sollte deutlich schneller sein.
                   2091:   - neuer Kommandozeilen-Parameter "--configtest": die Konfiguration wird
                   2092:     gelesen und dann die verwendeten Werte angezeigt.
                   2093:   - Client-Mode "s" (Server Notices) implementiert.
                   2094:   - mit dem neuen Kommandozeilen-Parameter "--config"/"-f" kann eine
                   2095:     alternative Konfigurationsdatei angegeben werden.
                   2096:   - nach dem Start kann der ngIRCd, wenn er mit root-Rechten laeuft,
                   2097:     zu einer anderen User-ID und Group-ID wechseln.
                   2098:   - URL der Homepage wird u.a. bei "--version" mit angezeigt.
                   2099:
                   2100: ngIRCd 0.3.0, 02.03.2002
                   2101:
                   2102:   - bekommt der Server ein HUP-Signal, so startet er neu -- genau so, wie
                   2103:     er auf den IRC-Befehl RESTART reagiert.
                   2104:   - FAQ um Hinweise auf den Bugtracker erweitert.
                   2105:   - neuer Kommandozeilen-Schalter "--passive" (-p): wird er angegeben, so
                   2106:     verbindet sich der ngIRCd nicht mehr automatisch zu anderen Servern.
                   2107:     Zum Debuggen manchmal ganz praktisch :-)
                   2108:   - direkt nach dem Start schreibt der ngIRCd nun die aktiven Kommando-
                   2109:     zeilenschalter in's Logfile (Passive, Debug, Sniffer ...).
                   2110:   - das Signal-Flag SA_RESTART wird nur noch gesetzt, wenn es auf dem
                   2111:     jeweiligen System auch definiert ist.
                   2112:   - bei ausgehenden Verbindungen wird nun der Ziel-Port protokolliert.
                   2113:   - neue Befehle VERSION und KILL implementiert.
                   2114:   - make-Target "check" (und "distcheck") mit Sinn erfuellt :-)
                   2115:     (die Tests sind aber bisher nicht all zu tiefgehend ...)
                   2116:   - Durch einen Ueberlauf konnte die Idle-Time bei WHOIS negativ werden ...
                   2117:   - Anpassungen an A/UX: gehoert nun auch zu den unterstuetzten Platformen.
                   2118:   - WHOIS wird nicht mehr automatisch an den "Original-Server" weiterge-
                   2119:     leitet: war eh nicht RFC-konform und machte mit Clients Probleme.
                   2120:   - an User wird nun immer ein "komplettes" Prefix (mit Host-Mask) ver-
                   2121:     schickt, Server bekommen nach wie vor kurze: das "Original" hat bei
                   2122:     bestimmten Befehlen (PRIVMSG) ansonsten evtl. Probleme ...
                   2123:   - NAMES korrigiert und vollstaendig implementiert.
                   2124:   - SQUIT wird auf jeden Fall geforwarded, zudem besseres Logging.
                   2125:   - Ist ein Nick bei der User-Registrierung bereits belegt, nimmt der
                   2126:     Server nun korrekt weitere NICK-Befehle an und verwendet diese.
                   2127:   - PRIVMSG beachtet nun die Channel-Modes "n" und "m".
                   2128:   - AWAY implementiert. PRIVMSG, MODE, USERHOST und WHOIS angepasst.
                   2129:   - der ngIRCd unterstuetzt nun Channel-Topics (TOPIC-Befehl).
                   2130:   - ausgehende Server-Verbindungen werden nun asynchron connectiert und
                   2131:     blockieren nicht mehr den ganzen Server, wenn die Gegenseite nicht
                   2132:     erreicht werden kann (bis zum Timeout konnten Minuten vergehen!).
                   2133:   - Wert der Konfigurations-Variable "ConnectRetry" wird besser beachtet.
                   2134:   - Channel- und Nicknames werden nun ordentlich validiert.
                   2135:
                   2136: ngIRCd 0.2.1, 17.02.2002
                   2137:
                   2138:   - NICK korrigiert: es werden nun auch alle "betroffenen" User informiert.
                   2139:   - configure-Script erweitert, u.a. bessere Anpassung an BeOS: dort wird
                   2140:     nun die "libbe" zum ngIRCd gelinkt, somit funktioniert auch syslog.
                   2141:   - Fehlerhafte bzw. noch nicht verstandene Modes werden nun ausfuehrlicher
                   2142:     an den Client geliefert.
                   2143:
                   2144: ngIRCd 0.2.0, 15.02.2002
                   2145:
                   2146:   - Nicknames und Channel-Namen werden etwas besser auf Gueltigkeit ueber-
                   2147:     prueft; ist aber nach wie vor noch nicht ausreichend.

                   2150:     Server versteht an User-Modes o und v, beachtet letzteres allerdings
                   2151:     noch nirgends. Bekannte (aber nicht beachtete!) Channel-Modes sind
                   2152:     bisher a, m, n, p, q, s und t. Diese Modes werden von Usern ange-
                   2153:     nommen, von anderen Servern werden auch unbekannte Modes uebernommen.

                   2162:   - Server-Verbindungen werden nun nach dem Start erst nach einer kurzen
                   2163:     Pause aufgebaut (zur Zeit drei Sekunden).
                   2164:   - Hilfetext korrigiert: --help und --version waren vertauscht, die

                   2175:   - Signal-Hander geaendert: die Fehlermeldung "interrupted system call"
                   2176:     sollte so nicht mehr auftreten.
                   2177:   - "spaeter" neu connectierende Server werden nun im Netz angekuendigt.

                   2185:     "Sub-Server" haben, also sowohl als Leaf-Node als auch Hub in einem
                   2186:     IRC-Netzwerk arbeiten.
                   2187:   - MODE und NICK melden nun die Aenderungen an andere Server, ebenso

                   2192:   - Log-Meldungen und Log-Level ueberarbeitet und korrigiert.
                   2193:   - Kommandozeilen-Parser: Debug- und No-Daemon-Modus, Hilfe.
                   2194:   - ngIRCd wandelt sich nun in einen Daemon (Hintergrundprozess) um.
                   2195:   - WHOIS korrigiert: Anfrage wurde u.U. an User geforwarded anstatt vom
                   2196:     Server beantwortet zu werden.

                   2201:
                   2202:   - Struktur der Konfigurationsdatei geaendert: sie ist nun "Samba like",
                   2203:     d.h. sie besteht aus Abschnitten (siehe "doc/sample-ngircd.conf").
                   2204:   - Es koennen mehrere IRC-Server-Opertatoren konfiguriert werden.
                   2205:   - Zombies der Resolver-Prozesse werden nun ordentlich "getoetet".

                   2212:     Befehle sind auch noch nicht (optimal) angepasst: PRIVMSG funktioniert
                   2213:     aber bereits, ebenso wie WHOIS (letzterer wird immer an den Server,
                   2214:     auf dem der User registriert ist, weitergegeben).

                   2216:   - Fehler bei select() fuerhen nun zum Abbruch von ngIRCd, bisher landete

                   2219:   - lokalen Usernamen wird nun ein "~" vorangestellt, da bisher noch keine
                   2220:     Ident-Anfragen gemacht werden.
                   2221:
                   2222: ngIRCd 0.0.1, 31.12.2001
