-ngIRCd 22
+ngIRCd 25 (2019-01-23)
+
+  - Fix documentation of MotdPhrase length, which actually is 126 characters:
+    update sample configuration file as well as the man page. Thanks to
+    shankari <shankari@eecs.berkeley.edu>.
+    Closes #254.
+  - Implement new configuration option "MaxPenaltyTime", which configures the
+    maximum penalty time increase in seconds, per penalty event. Set to -1 for
+    no limit (the default), 0 to disable penalties altogether. ngIRCd doesn't
+    use penalty increases higher than 2 seconds during normal operation, so
+    values higher than 1 rarely make sense.
+    Disabling (or reducing) penalties can greatly speed up "make check" runs
+    for example, see below, but are mostly a debugging feature and normally
+    not meant to be used on production systems!
+    Some example timings running "make check" from my macOS workstation:
+     - MaxPenaltyTime not set: 4:41,79s
+     - "MaxPenaltyTime = 1":   3:14,71s
+     - "MaxPenaltyTime = 0":     25,46s
+    Closes #249 and #251.
+  - Fix compilation without deprecated OpenSSL APIs. Thanks to Rosen Penev
+    <rosenp@gmail.com> for the patch!
+    Closes #252.
+  - Update Xcode project for latest Xcode version (10.0)
+  - Fix some compiler warnings of Apple Xcode/Clang
+  - Allow a 5th parameter in WEBIRC. Thanks to "ItsOnlyBinary".
+    Closes #247.
+  - Update some more documentation files and source code comments.
+  - Platforms.txt: Add and update systems.
+
+  ngIRCd 25~rc1 (2018-08-11)
+  - Update config.guess (2018-03-08) and config.sub (2018-03-08) files.
+  - Correctly retry to establish an outgoing connections when forking of the
+    resolver sub-process failed (for example because of lack of free memory).
+    Until now, such a connection was never retried once this error was hit.
+    Thanks to Robert Obermeier for reporting this bug!
+    Closes #243.
+  - Fix a "use after free" bug which can be triggered on a newly established
+    connection when the daemon handles an ERROR command received from the peer
+    during client login. Thanks a lot to Joseph Bisch <joseph.bisch@gmail.com>
+    for discovering and reporting this issue!
+  - Only send TOPIC updates to a channel when the topic actually changed:
+    This prevents the channel from becoming flooded by unnecessary TOPIC update
+    messages, that can happen when IRC services try to enforce a certain topic
+    but which is already set (at least on the local server), for example.
+    Therefore still forward it to all servers, but don't inform local clients
+    (still update setter and timestamp information, though).
+  - Update Xcode project for latest Xcode version (9.2). This includes adding
+    missing and deleting obsolete file references.
+  - Handle user mode "C" ("Only users that share a channel are allowed to send
+    messages") like user mode "b" ("block private messages and notices"): allow
+    messages from servers, services, and IRC Operators, too. Change proposed by
+    "wowaname" back in 2015 in #ngircd, thanks!
+  - Fix some compiler warnings.
+  - Add contrib/ngircd.logcheck: Some sample logcheck(8) rules.
+  - Allow IRC Ops and remote servers to KILL service clients: such clients
+    behave like regular users, therefore IRC operators and servers should be
+    able to KILL them: for example to resolve nick collisions.
+    Closes #242.
+  - Don't forward KILLs to other servers if they've been blocked locally:
+    This prevents clients from killing IRC services, for example.
+    Closes #238 and #239.
+  - Fix a cross-compiler issue related to the Get_Error() function.
+    Closes #240 and #241.
+  - Update ./doc/Services.txt, enhance configuration examples.
+
+ngIRCd 24 (2017-01-20)
+
+  - Make sure that ./contrib/platformtest.sh aborts when ./autogen.sh fails.
+  - Update config.guess (2016-10-02) and config.sub (2016-11-04) files.
+  - Build Debian packages with OpenSSL instead of GnuTLS: OpenSSL allows
+    to reload used certificates on runtime for example (which is very
+    useful when using Let's Encrypt), and therefore is preferred. And
+    explicitly specify the "source format".
+  - Fix handling of connection pool allocation and enlargement: up to now,
+    the daemon only enlarged its connection pool when accepting new incoming
+    client or server connections, not when establishing new outgoing server
+    links, which could lead to problems when hitting the configured limit,
+    see "MaxConnections". Thanks to Lukas Braun (k00mi) for reporting this!
+    Closes #231.
+
+  ngIRCd 24~rc1 (2017-01-07)
+  - Enhance systemd service file, and install it in Debian package.
+  - Update configuration of Debian package.
+  - Log privilege violations and failed OPER request with log level "error"
+    and send it to the "&SERVER" channel, too.
+  - Immediately shut down connection when receiving an "ERROR" command,
+    don't wait for the peer to close the connection. This allows the daemon
+    to forward the received "ERROR" message in the network, instead of the
+    very generic "client closed connection" message.
+  - Fix sending of entry duration (no negative values!) when synchronizing
+    "x-lines" (G-LINES).
+  - List expiration (G-LINES): use same log level as when setting, and log
+    this event to the &SERVER channel, too.
+  - Explicitly forbid remote servers to modify "x-lines" (G-LINES) when the
+    "AllowRemoteOper" configuration option isn't set, even when the command
+    seems to originate from the remote server itself: this prevents GLINE's
+    to become set during server handshake in this case (what wouldn't be
+    possible during regular runtime when a remote IRC Op sends the command)
+    and what can't be undone by IRC Ops later on (because of the missing
+    "AllowRemoteOper" option) ...
+  - Make scripts and init-files in ./contrib executable.
+  - Fix building ngIRCd with OpenSSL 1.1. Thanks to Christoph Biedl
+    <ngircd.anoy@manchmal.in-ulm.de> for the patch!
+  - Fix code indentation warnings of gcc 6.2.
+  - Update config.guess (2016-04-02) and config.sub (2016-03-30) files.
+  - Fix warnings of the "shellcheck" linter in autogen.sh, contrib/ngindent
+    and contrib/platformtest.sh.
+  - Update Xcode project for latest Xcode version (8.0), and fix "duplicate
+    symbols" error messages when building (linking) the binary.
+  - Add "Documentation" variables to systemd configuration files.
+  - Make sure that SYSCONFDIR is always set, which can be handy when
+    using source code linters when ./configure hasn't been run already.
+  - Add the new "PAMServiceName" configuration option to specify the name
+    used as PAM service name. This setting allows to run multiple ngIRCd
+    instances with different PAM configurations for each instance.
+    Thanks to Christian Aistleitner <christian@quelltextlich.at> for the
+    patch, closes #226.
+  - Add an ".editorconfig" file to the project.
+  - Travis-CI: use "container-based infrastructure".
+  - Limit the number of message targets, and suppress duplicates: This
+    prevents an user from flooding the server using commands like this:
+    "PRIVMSG nick1,nick1,nick1,...".
+    Duplicate targets are suppressed silently (channels and clients).
+    In addition, the maximum number of targets per PRIVMSG, NOTICE, ...
+    command are limited to MAX_HNDL_TARGETS (25). If there are more, the
+    daemon sends the new 407 (ERR_TOOMANYTARGETS_MSG) numeric, containing
+    the first target that hasn't been handled any more. Closes #187.
+  - Test suite: Add new test for server-server logins.
+  - contrib/ngindent: Fix shebang line.
+  - Make contrib/platformtest.sh script more portable, and only show
+    "runs=Y" when the test suite really has been passed successfully.
+  - Code cleanup in the NJON handler and the function killing clients as
+    well as the function sending messages to a "mask" (cleaner code, more
+    fault tolerant, better code comments).
+  - Update and enhance documentation: README file, doc/Platforms.txt,
+    doc/Modes.txt, doc/Commands.txt, doc/PAM.txt.
+  - Fix NJOIN not propagating "half ops" status: ngIRCd tested for the wrong
+    prefix of "half ops" when processing NJOIN commands and therefore never
+    classified a remote user as "half op".
+    Thanks to wowaname for pointing this out on #ngircd!
+
+ngIRCd 23 (2015-11-16)
+
+  - Explicitly cast time_t to long when printing it out: this prevents
+    wrong sized data types on platforms where time_t doesn't equal a
+    long any more, for example on OpenBSD (which would result in garbled
+    output on those platforms).
+  - contrib/Debian/changelog: Fix email address.
+  - Documentation: Spelling fixes; update doc/Platforms.txt.
+
+  ngIRCd 23~rc1 (2015-09-06)
+  - Add ".clang_complete" file, which is used by the "linter-clang" package
+    of the Atom editor, for example.
+  - Make server-to-server protocol more robust: ngIRCd now catches more
+    errors on the server-to-server (S2S) protocol that could crash the
+    daemon before. This hasn't been a real problem because the IRC S2S
+    protocol is "trusted" by design, but the behavior is much better now.
+    Thanks to wowaname on #ngircd for pointing this out!
+  - Make platformtest.sh, autogen.sh, and ngircd.init more portable.
+  - Enables "reproducible builds" for ngIRCd: Use the optional BIRTHTIME
+    constant while building ngIRCd, which contains a time stamp for the
+    "Birth Date" information, in seconds since the epoch.
+    See <https://wiki.debian.org/ReproducibleBuilds>.
+  - Update "contrib/ngircd.service" file for systemd.
+  - INSTALL: Add deprecation notice for "PredefChannelsOnly" variable.
+  - Use "NOTICE *" before registration instead of "NOTICE AUTH". "AUTH" is
+    a valid nickname so sending notices to it is probably not a good idea.
+    Use "*" as the target instead as done with numerics when the nick is not
+    available. This mimics the behavior in Charybdis, IRCD-Hybrid, InspIRCd
+    2.2, Plexus 4, etc. Closes #217.
+    The "NoticeAuth" configuration variable (ngircd.conf) has been renamed
+    to "NoticeBeforeRegistration" accordingly, but the old name is still
+    supported for compatibility reasons.
+  - Implement new channel mode "N" (regular users can't change their nick
+    name while on this channel). Closes #214.
+  - README, AUTHORS: Update mailing list and issue tracker URLs.
+  - Remove doc/GIT.txt (it is outdated), update doc/Contributing.txt:
+    ngIRCd uses GitHub, and Git itself is quite common today. So don't
+    include an own Git "mini HowTo" any longer.
+  - Specify session context for OpenSSL clients. This enables some OpenSSL
+    clients, including Pidgin and stunnel 5.06, to reuse a session.
+    Patch by Tom Ryder <tom@sanctum.geek.nz>, thanks! Closes #182.
+  - Keep track of who placed bans, invites, and excepts.
+    Idea and implementation by LucentW, Thanks! Closes #203.
+  - Make setgroups(3) function optional: For example, Interix is missing
+    this function, which prevented ngIRCd to build on this platform. When
+    setgroups(3) isn't available, a warning message is issued on startup.
+  - Implement numeric RPL_LISTSTART(321). lightIRC and other clients
+    expecting RPL_LISTSTART should now behave correctly.
+    Idea and implementation by LucentW, Thanks! Closes #207.
+  - Update ngircd.conf.5: "CloakUserToNick" hides user _and_ real name.
+    This closes #208.
+  - Fix case insensitive pattern matching: Up to now, only the the input
+    string became lowercased and was then compared to the pattern -- which
+    failed when the pattern itself wasn't all lowercase!
+  - Streamline the effect of "MorePrivacy" option: Update documentation
+    in ngircd.conf(5); don't hide channels for IRC Ops on LIST and don't
+    hide IP addresses/hostnames on WHOIS when "MorePrivacy" is in effect.
+    This closes #198.
+  - IRC operators now can kick anyone when "OperCanMode" is set.
+    Idea and implementation by LucentW, Thanks! Closes #202.
+  - Implement user mode "I": Hide channels on WHOIS: this mode prevents
+    ngIRCd from showing channels on WHOIS (IRC Operators can always see
+    the channel list).
+    Idea and implementation by LucentW, Thanks! Closes #197.
+  - INVITE command: Implement ERR_USERNOTONSERV(504) numeric and make sure
+    that the target user is on the same server when inviting other users
+    to local ("&") channels.
+    Idea by Cahata, thanks! Closes #183.
+  - INVITE command: Enforce 1 second penalty time, which prevents flooding
+    of the target client.
+    This closes #186. Reported by Cahata, thanks!
+  - MODE command: Always report channel creation time. Up to now when
+    receiving a MODE command, ngIRCd only reported the channel creation
+    time to clients that were members of the channel. This patch reports
+    the channel creation time to all clients, regardless if they are joined
+    to that channel or not. At least ircd-seven behaves like this.
+    This closes #188. Reported by Cahata, thanks!
+  - Update Xcode project for latest Xcode version (6.3).
+
+ngIRCd 22.1 (2015-04-06)
+
+  - Update doc/Platforms.txt and doc/FAQ.txt.
+  - Fix spelling of RPL_WHOISBOT message text.
+  - Don't send nick name as default PART reason: No other IRC daemon seems
+    to do this (today?). Closes #185.
+    Reported by Cahata in #ngircd, thanks!
+  - Fix "WHO #<chan>" showing invisible users and hiding all visible, the
+    logic was reversed! This bug has been introduced by commit c74115f2,
+    "Simplify mode checking on channels and users within a channel", ngIRCd
+    releases 21, 21.1, and 22 are affected :-( Problem reported by Cahata
+    in #ngircd, Thanks!
+  - Fix typo in src/testsuite/README
+  - Auth PING: Fix our information text for manual sending of "PONG". Up to
+    now, ngIRCd doesn't send a valid IRC command at all, oops!
+  - Auth PING: Fix internal time stamp conversion and don't send a prefix in
+    our PING command. The prefix confuses WeeChat, at least, which doesn't
+    send an appropriate PONG in the case ...
+    Debugging and patch by "wowaname" on #ngircd, thanks!
+  - Fix syntax of ERR_LISTFULL_MSG(478) numeric. Pointed out by "wowaname"
+    in #ngircd, thanks!
+  - Enhance debug messages while sending CHANINFO commands.
+  - Reset "last try" timer when enabling a passive server. This results in
+    a new connection attempt as soon as possible.
+  - Change log message for "Can't resolve address" and for IP address
+    forgeries.
+  - doc/HowToRelease.txt: Add note about the bug tracker.
+  - Update "CipherList" to not enable SSLv3 by default. Idea, initial patch,
+    and testing by Christoph Biedl <ngircd.anoy@manchmal.in-ulm.de>.
+  - Change ngIRCd test suite not to use DNS lookups: Different operating
+    systems do behave quite differently when doing DNS lookups, for example
+    "127.0.0.1" sometimes resolves to "localhost" and sometimes to
+    "localhost.localdomain" (for example OpenBSD). And other OS resolve
+    "localhost" to the real host name (for example Cygwin). So not using
+    DNS at all makes the test site much more portable.
+
+ngIRCd 22 (2014-10-11)
+
+  - Match all list patterns case-insensitive: this affects the invite-,

-ngIRCd 22
+  - Implement new configuration option "MaxPenaltyTime", which configures the
+    maximum penalty time increase in seconds, per penalty event. Set to -1 for
+    no limit (the default), 0 to disable penalties altogether. ngIRCd doesn't
+    use penalty increases higher than 2 seconds during normal operation, so
+    values higher than 1 rarely make sense.
+    Disabling (or reducing) penalties can greatly speed up "make check" runs
+    for example, see below, but are mostly a debugging feature and normally
+    not meant to be used on production systems!
+    Some example timings running "make check" from my macOS workstation:
+     - MaxPenaltyTime not set: 4:41,79s
+     - "MaxPenaltyTime = 1":   3:14,71s
+     - "MaxPenaltyTime = 0":     25,46s
+    Closes #249 and #251.
+  - Update Xcode project for latest Xcode version (10.0)
+  - Allow a 5th parameter in WEBIRC. Thanks to "ItsOnlyBinary".
+    Closes #247.
+
+  ngIRCd 25~rc1 (2018-08-11)
+  - Only send TOPIC updates to a channel when the topic actually changed:
+    This prevents the channel from becoming flooded by unecessary TOPIC update
+    messages, that can happen when IRC services try to enforce a certain topic
+    but which is already set (at least on the local server), for example.
+    Therefore still forward it to all servers, but don't inform local clients
+    (still update setter and timestamp information, though!).
+  - Update Xcode project for latest Xcode version (9.2). This includes adding
+    missing and deleting obsolete file references.
+  - Handle user mode "C" ("Only users that share a channel are allowed to send
+    messages") like user mode "b" ("block private messages and notices"): allow
+    messages from servers, services, and IRC Operators, too. Change proposed by
+    "wowaname" back in 2015 in #ngircd, thanks!
+  - Allow IRC Ops and remote servers to KILL service clients: such clients
+    behave like regular users, therefore IRC operators and servers should be
+    able to KILL them: for example to resolve nick collisions.
+    Closes #242.
+
+ngIRCd 24 (2017-01-20)
+
+  ngIRCd 24~rc1 (2017-01-07)
+  - Log privilege violations and failed OPER request with log level "error"
+    and send it to the "&SERVER" channel, too.
+  - Immediately shut down connection when receiving an "ERROR" command,
+    don't wait for the peer to close the connection. This allows the daemon
+    to forward the received "ERROR" message in the network, instead of the
+    very generic "client closed connection" message.
+  - Explicitly forbid remote servers to modify "x-lines" (G-LINES) when the
+    "AllowRemoteOper" configuration option isn't set, even when the command
+    seems to originate from the remote server itself: this prevents GLINE's
+    to become set during server handshake in this case (what wouldn't be
+    possible during regular runtime when a remote IRC Op sends the command)
+    and what can't be undone by IRC Ops later on (because of the missing
+    "AllowRemoteOper" option) ...
+  - Update Xcode project for latest Xcode version (8.0), and fix "duplicate
+    symbols" error messages when building (linking) the binary.
+  - Add "Documentation" variables to systemd configuration files.
+  - Make sure that SYSCONFDIR is always set, which can be handy when
+    using source code linters when ./configure hasn't been run already.
+  - Add the new "PAMServiceName" configuration option to specify the name
+    used as PAM service name. This setting allows to run multiple ngIRCd
+    instances with different PAM configurations for each instance.
+    Thanks to Christian Aistleitner <christian@quelltextlich.at> for the
+    patch, closes #226.
+  - Add an ".editorconfig" file to the project.
+  - Limit the number of message target, and suppress duplicates: This
+    prevents an user from flooding the server using commands like this:
+    "PRIVMSG nick1,nick1,nick1,...".
+    Duplicate targets are suppressed silently (channels and clients).
+    In addition, the maximum number of targets per PRIVMSG, NOTICE, ...
+    command are limited to MAX_HNDL_TARGETS (25). If there are more, the
+    daemon sends the new 407 (ERR_TOOMANYTARGETS_MSG) numeric, containing
+    the first target that hasn't been handled any more. Closes #187.
+  - Make contrib/platformtest.sh script more portable, and only show
+    "runs=Y" when the test suite really has been passed successfully.
+
+ngIRCd 23 (2015-11-16)
+
+  ngIRCd 23~rc1 (2015-09-06)
+  - Use "NOTICE *" before registration instead of "NOTICE AUTH". "AUTH" is
+    a valid nickname so sending notices to it is probably not a good idea.
+    Use "*" as the target instead as done with numerics when the nick is not
+    available. This mimics the behavior in Charybdis, IRCD-Hybrid, InspIRCd
+    2.2, Plexus 4, etc. Closes #217.
+    The "NoticeAuth" configuration variable (ngircd.conf) has been renamed
+    to "NoticeBeforeRegistration" accordingly, but the old name is still
+    supported for compatibility reasons.
+  - Implement new channel mode "N" (regular users can't change their nick
+    name while on this channel). Closes #214.
+  - Keep track of who placed bans, invites, and excepts.
+    Idea and implementation by LucentW, Thanks! Closes #203.
+  - Implement numeric RPL_LISTSTART(321). lightIRC and other clients
+    expecting RPL_LISTSTART should now behave correctly.
+    Idea and implementation by LucentW, Thanks! Closes #207.
+  - Streamline the effect of "MorePrivacy" option: Update documentation
+    in ngircd.conf(5); don't hide channels for IRC Ops on LIST and don't
+    hide IP addresses/hostnames on WHOIS when "MorePrivacy" is in effect.
+    This closes #198.
+  - IRC operators now can kick anyone when "OperCanMode" is set.
+    Idea and implementation by LucentW, Thanks! Closes #202.
+  - Implement user mode "I": Hide channels on WHOIS: this mode prevents
+    ngIRCd from showing channels on WHOIS (IRC Operators can always see
+    the channel list).
+    Idea and implementation by LucentW, Thanks! Closes #197.
+  - INVITE command: Implement ERR_USERNOTONSERV(504) numeric and make sure
+    that the target user is on the same server when inviting other users
+    to local ("&") channels.
+    Idea by Cahata, thanks! Closes #183.
+  - MODE command: Always report channel creation time. Up to now when
+    receiving a MODE command, ngIRCd only reported the channel creation
+    time to clients that were members of the channel. This patch reports
+    the channel creation time to all clients, regardless if they are joined
+    to that channel or not. At least ircd-seven behaves like this.
+    This closes #188. Reported by Cahata, thanks!
+
+ngIRCd 22.1 (2015-04-06)
+
+  - Update "CipherList" to not enable SSLv3 by default. Idea, initial patch,
+    and testing by Christoph Biedl <ngircd.anoy@manchmal.in-ulm.de>.
+  - Change ngIRCd test suite not to use DNS lookups: Different operating
+    systems do behave quite differently when doing DNS lookups, for example
+    "127.0.0.1" sometimes resolves to "localhost" and sometimes to
+    "localhost.localdomain" (for example OpenBSD). And other OS resolve
+    "localhost" to the real host name (for example Cygwin). So not using
+    DNS at all makes the test site much more portable.

-
-
-The source code of ngIRCd is maintained using GIT, an distributed version
-control system. Homepage including documentation: <http://git-scm.com/>.
-
-
-I. Viewing the source code online
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The ngIRCd "GITweb" interface allows you to browse the GIT repository and
-to see all individual files, tags, branches, commits etc.:
-
- <http://arthur.barton.de/cgi-bin/gitweb.cgi?p=ngircd.git>
-
-
-II. Getting the source code
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-To access (copy, clone) the source tree repository anonymously, run:
-
- $ git clone git://ngircd.barton.de/ngircd.git
-
-Thereby a new folder "ngircd" will be created containing all the individual
-source files.
-
-The newly created directory ("ngircd") is the "working directory", all
-GIT commands will be executed from within this directory in the future.
-
-Please note: When checking out a fresh copy of ngIRCd using GIT, the
-configure script doesn't exist; you have to run the autogen.sh shell script
-(which is included in the source tree) to generate it. This requires you to
-have GNU automake and GNU autoconf installed on your system. Please see the
-file INSTALL for details!
-
-To update the local GIT repository:
-
- $ git pull
-
-This retrieves all changes and merges them into the current branch.
-
-
-III. Contributing
-~~~~~~~~~~~~~~~~~
-
-Patches should be sent to the ngircd mailing list. List homepage:
-http://arthur.barton.de/mailman/listinfo/ngircd-ml
-
-If you do not want to send them to the list, you can also mail them
-to Alex Barton, <alex@barton.de>.
-
-
-IV. Write Access
-~~~~~~~~~~~~~~~~
-
-If you want to contribute a couple of patches and write access to the GIT
-repository would be handy, please contact Alex Barton, <alex@barton.de>.
