+ngIRCd 22 (2014-10-11)
+
+  - Match all list patterns case-insensitive: this affects the invite-,
+    ban-, and except lists, as well as G-Lines an K-Lines.
+    Problem pointed out by "wowaname" on #ngircd, thanks!
+
+  ngIRCd 22~rc1 (2014-09-29)
+  - Sync "except lists" between servers: Up to now, ban, invite, and G-Line
+    lists have been synced between servers while linking -- but obviously
+    nobody noticed that except list have been missing ever since. Until now.
+    Thanks to "j4jackj", who reported this issue in #ngircd.
+  - Allow longer user names (up to 63 characters) for authentication.
+  - Correctly check that a server has a valid hostname and port, thanks to
+    David Binderman <dcb314@hotmail.com> who reported this bug.
+  - Fix the function which generates complete "IRC masks" from user input,
+    don't destroy the source buffer and use all provided parts (nick, user,
+    host name). This fixes GLINEs/KLINEs from not working in some situations.
+  - Increase MAX_SERVERS from 16 to 64: There are installations out there
+    that would like to configure more than 16 links per server, so increase
+    this limit. Best would be to get rid of MAX_SERVERS altogether and make
+    if fully dynamic, but start with this quick and dirty hack ...
+  - Debian: Don't adjust path names that are correct by default and correctly
+    set and use "docdir".
+  - Update config.guess and config.sub to recent versions.
+  - Test suite/platformtest.sh: Detect when tests have been skipped.
+  - doc/Bopm.txt: Update "connregex" and "kline" for current ngIRCd.
+  - Allow "DefaultUserModes" to set all possible modes, including modes only
+    settable by IRC Operators.
+  - Spoofed prefixes: Really kill connection on non-server links.
+  - Implement user mode "F": "relaxed flood protection". Clients with mode
+    "F" set are allowed to rapidly send data to the daemon. This mode is only
+    settable by IRC Operators and can cause problems in the network -- so be
+    careful and only set it on "trusted" clients!
+    User mode "F" is used by Bahamut for this purpose, for example.
+  - Handle "throttling" in a single function: ngIRCd implements "command
+    throttling" and "bps throttling" (bytes per second). The states are
+    detected in different functions, Conn_Handler() and Read_Request(), but
+    handle the actual "throttling" in a common function: this enables us to
+    guarantee consistent behavior and to disable throttling for special
+    connections in only one place
+  - Use server password when PAM is compiled in but disabled.
+  - Streamline punctuation of log messages.
+  - Return ISUPPORT(005) numerics on "VERSION". This is how ircd-seven,
+    Charybdis, Hybrid, and InspIRCd behave, for example.
+  - configure: Only link "contrib/Debian" if it exists, which isn't the case
+    on "VPATH builds", for example.
+  - Show the account name in WHOIS. This uses the same numeric as Charybdis
+    and ircu families: WHOISLOGGEDIN(330).
+  - Pattern matching: Remove "range matching" in our pattern matching code
+    using the "[...]" syntax, because [ and ] are valid characters in nick
+    names and one has to quote them currently using the "\" character, which
+    is quite unexpected for users.
+  - platformtest.sh: New option "-x", don't regenerate build system and
+    allow using separate source and build trees.
+  - Test suite: explicitly enable glibc memory checking.
+  - Make "MODE -k" handling more robust and compatible, send "fake '*' key"
+    in all replies.
+  - Update configure.ng: ngIRCd requires GNU autoconf 2.61 for generating its
+    build system, so update the build system accordingly and implement all
+    changes that autoupdate(1) suggests: Update AC_PREREQ and AC_INIT, use
+    AC_LINK_IFELSE, AC_RUN_IFELSE, and AC_COMPILE_IFELSE, and remove
+    AC_TYPE_SIGNAL (we don't use RETSIGTYPE).
+  - portabtest: Actually test the functions snprintf(), strlcpy(), strlcat(),
+    and vsnprintf() for correctness, not only existence (which was quite
+    useless, because if they weren't available, the program could not have
+    been linked at all ...).
+  - Implement new configuration option "Network": it is used to set the
+    (completely optional) "network name", to which this instance of the
+    daemon belongs. When set, this name is used in the ISUPPORT(005) numeric
+    which is sent to all clients connecting to the server after logging in.
+  - Update doc/Platforms.txt.
+  - Various code cleanups, remove unused code, streamline error handling.
+    Remove all imp.h and exp.h header files, support non-standard vsnprintf()
+    return codes, and fix some K&R C portability issues. Streamline
+    DEBUG_ARRAY, DEBUG_BUFFER, DEBUG_IO, DEBUG_ZIP definitions.
+  - Increase penalty time to 10 seconds when handling OPER commands with an
+    invalid password.
+
+ngIRCd 21.1 (2014-03-25)
+
+  - Don't ignore but use the server password when PAM is compiled in but
+    disabled. Thanks to Roy Sindre Norangshol <roy.sindre@norangshol.no>!
+  - doc/Platforms.txt: Update from master branch.
+  - Really kill connections that send "spoofed prefixes" on non-server links.
+    This fixes commit 6cbe1308 which only killed the connection when the
+    spoofed prefix itself belonged to a non-server client.
+  - CHARCONV command: Fix handling conversion errors, don't overwrite already
+    converted text!
+  - doc/Services.txt: Update information for Anope 2.x.
+  - Correctly use cloaked IRC masks on "INVITE nickname": The cloaked IRC mask
+    of a user is his visible mask, so the daemon has to use it for generating
+    the "one time" entries for the invite list of the given channel, and not
+    the "real" mask which will never match while the target client is "+x", and
+    even worse, will disclose the real mask on "MODE #channel +I" commands :-/
+    Bug reported by Cahata on #ngircd, thanks!
+  - configure: Only link "contrib/Debian" if it exists. This isn't the case on
+    "VPATH builds", for example.
+  - Use $(MKDIR_P) instead of $(mkinstalldirs) in Makefile's and test for
+    "mkdir -p" using AC_PROG_MKDIR_P in "configure".
+  - Fix configure script and "make check" for TCP Wrappers (problems spotted on
+    OpenBSD): add missing #include's and static variables, and add libwrap at
+    the end of the configure run because if libwrap becomes added earlier,
+    other tests may fail.
+  - configure: add support for the LDFLAGS_END and LIBS_END variables to add
+    linker flags and libraries at the end of the configure run (CFLAGS_END has
+    been implemented already).
+  - platformtest.sh and Makefile.am: Don't use "test -e", it isn't portable.
+  - Update Copyright notices for 2014 :-)
+  - Fix permanent {G|K}LINES (with a timeout of 0 seconds).
+  - WEBIRC: Don't set the hostname received by the WEBIRC command when DNS
+    lookups are disabled, but use the IP address instead.
+    Reported by Toni Spets <toni.spets@iki.fi>, thanks!
+  - Check for working getaddrinfo() function: At least AIX 4.3.3 and 5.1 have a
+    broken implementation of getaddrinfo() which doesn't handle "0" as numeric
+    service correctly. This patch adds a configure check for this case and
+    changes all calling functions to only use getaddrinfo() if it "works".
+    See <http://www.stacken.kth.se/lists/heimdal-discuss/2004-05/msg00059.html>
+  - Only use the unsetenv() function when it is available (AIX 4.3 doesn't
+    support it, for example).
+  - Make sure that the source code is still compatible with the "ansi2knr" tool
+    and builds using non-ANSI K&R C compilers. Tested with Apple C on A/UX.
+  - Fix building ngIRCd without support for ZLIB compression.  Reported by
+    "der_baer" on #ngircd, thanks!
+
+ngIRCd 21 (2013-10-30)
+
+  - ./contrib/Debian/ngircd.init: Make sure no stale PID file is left over
+    when (re-)starting ngIRCd.
+  - Change ./contrib/platformtest.sh and update ./doc/Platforms.txt to
+    allow user names up to 8 characters.
+  - Call arc4random_stir() in forked subprocesses, when available. This
+    is required by FreeBSD <10 and current NetBSD at least to correctly
+    initialize the "arc4" random number generator on these platforms.
+  - Update our own Debian package configuration and fix the default path
+    of the "HelpFile" of the "full" package variants.
+
+  ngIRCd 21~rc2 (2013-10-20)
+  - Report the correct configuration file name on configuration errors,
+    support longer configuration lines, and warn when lines are truncated.
+  - Use arc4random() function to generate "random" numbers, when available.
+  - platformtest.sh: Detect clang compiler, and clean up GIT source tree
+    before building (when possible).
+  - Update (date of) manual pages.
+  - Update "Upgrade Information" in INSTALL file, add more systems to
+    doc/Platforms.txt, and fix spelling in NEWS and ChangeLog files =:)
+  - Fix remaining compiler warnings on OpenBSD.
+
+  ngIRCd 21~rc1 (2013-10-05)
+  - Actually KILL clients on GLINE/KLINE. (Closes bug #156)
+  - Adjust log messages for invalid and spoofed prefixes, which cleans up
+    logging of commands related to already KILL'ed clients. And don't
+    forward KILL commands for (already) unknown clients any more to prevent
+    unnecessary duplicates.
+  - Add support to show all user links using the "STATS L" (uppercase)
+    command (restricted to IRC Operators).
+  - Fixed blocking of server reconnects in some error configurations.
+  - Don't ignore SSL-related errors during startup any more: abort startup
+    when SSL is requested by the configuration but can't be initialized and
+    don't continue only listening on plain text communication ports.
+    (Closes bug #163)
+  - Implement configurable SSL cipher list selection for GnuTLS and OpenSSL
+    using the new configuration option "CipherList". In addition, this
+    changes the defaults to more secure values: "HIGH:!aNULL:@STRENGTH" for
+    OpenSSL, and "SECURE128" for GnuTLS.
+  - Fix "TRACE": Correctly return ERR_NEEDMOREPARAMS(461) (which basically
+    is "syntax error") when there are too many parameters.
+  - Clean up lots of permission and parameter checks in functions handling
+    IRC commands; and more consistently add penalty times on errors.
+  - Fix error numeric of WHOIS when no nick name has been provided:
+    as per RFC it should be ERR_NONICKNAMEGIVEN(431).
+  - Only log "IDENT ... no result" messages when an IDENT looked took place
+    and didn't return any data, not when IDENT has been disabled.
+  - Show connection flag "s" (SSL) in RPL_TRACE{LINK|SERVER} messages: now
+    you can check if a server-to-server link is SSL-encrypted or not using
+    the IRC "TRACE" command.
+  - Correctly discard supplementary groups on server startup.
+  - Save client IP address text for "WebIRC" users and correctly display
+    it on WHOIS, for example. (Closes bug #159)
+  - Implement the new configuration option "DefaultUserModes" which lists
+    user modes that become automatically set on new local clients right
+    after login. Please note that only modes can be set that the client
+    could set on itself, so you can't set "a" (away) or "o" (IRC Op),
+    for example! User modes "i" (invisible) or "x" (cloaked) etc. are
+    "interesting", though. (Closes bug #160)
+  - Add support for the new METADATA "account" property, which allows
+    services to automatically identify users after netsplits and across
+    service restarts.
+  - Enforce "penalty times" on error conditions more consistently and in
+    more places. Now most error codes sent back from the IRC server to the
+    client should result in a 2 second "penalty".
+  - Implement a new configuration option "AllowedChannelTypes" that lists
+    all allowed channel types (channel prefixes) for newly created channels
+    on the local server. By default, all supported channel types are allowed.
+    If set to the empty string, local clients can't create new channels at
+    all, which equals the old "PredefChannelsOnly = yes" setting.
+    This change deprecates the "PredefChannelsOnly" variable, too, but it is
+    still supported and translated to the appropriate "AllowedChannelTypes"
+    setting. When the old "PredefChannelsOnly" variable is processed, a
+    warning message is logged. (Closes bug #152)
+  - Add support for "client certificate fingerprinting". When a client
+    passes an SSL certificate to the server, the "fingerprint" will be
+    forwarded in the network which enables IRC services to identify the
+    user using this certificate and not using passwords.
+  - IRC Operator names, as defined in ngircd.conf, are logged now when
+    handling successful OPER commands.
+  - Some error conditions while handling IRC commands, like "permission
+    denied" or "need more parameters", result in more penalty times.
+  - The numeric replies of some commands became split too early which
+    resulted in more numeric reply lines than necessary.
+  - Implement a new configuration option "IncludeDir" in the "[Options]"
+    section that can be used to specify a directory which can contain
+    further configuration files and configuration file snippets matching
+    the pattern "*.conf". These files are read in after the main server
+    configuration file ("ngircd.conf" by default) has been read in and
+    parsed.  The default is "$SYSCONFDIR/ngircd.conf.d", so that it is
+    possible to adjust the configuration only by placing additional files
+    into this directory. (Closes bug #157)
+  - Fix use-after-free in the Lists_CheckReason() function, which is used
+    to check if a client is a member of a particular ban/invite/... list.
+  - Xcode: fix detection of host OS, vendor, and CPU type, and update
+    project settings for Xcode 5.
+  - OS X PackageMaker: use relative path names in project files and package
+    with correct file permissions (requires root privileges on "make").
+  - Add Travis-CI configuration file (".travis.yml") to project.
+  - Look for possible cloaked Masks in Lists. Users with +x user mode can
+    be banned with their cloaked hostname now.
+  - Don't read SSL client data before DNS resolver is finished which could
+    have resulted in discarding the resolved client hostname and IDENT
+    reply afterwards, because in some situations (timing dependent) the
+    NICK and USER commands could have already been read in from the client,
+    stored in the buffer, and been processed.
+    Thanks to Julian Brost for reporting the issue and testing, and to
+    Federico G. Schwindt <fgsch@lodoss.net> for helping to debug it!
+  - Increase password length limit to 64 characters. (Closes bug #154)
+  - doc/Services.txt: Update Anope status and URL.
+  - Clean up Xcode project file, remove outdated files, add missing ones.
+  - Update Doxygen configuration file.
+  - configure: search for iconv_open as well as libiconv_open, because
+    on some installations iconv_open() is actually libiconv_open().
+    iconv_open() is the glibc version while libiconv_open() is the
+    libiconv version, now both variants are supported. (Closes bug #151)
+  - ngIRCd now accepts user names including "@" characters, saves the
+    unmodified name for authentication but stores only the part in front
+    of the "@" character as "IRC user name". And the latter is how
+    ircd2.11, Bahamut, and irc-seven behave as well. (Closes bug #155)
+  - Lots of IRC "information functions" like ADMIN, INFO, ... now accept
+    server masks and names of connected users (in addition to server names)
+    for specifying the target server of the command. (Closes bug #153)
+  - Implement a new configuration option "IdleTimeout" in the "[Limits]"
+    section of the configuration file which can be used to set a timeout
+    in seconds after which the whole daemon will shutdown when no more
+    connections are left active after handling at least one client.
+    The default is 0, "never".
+    This can be useful for testing or when ngIRCd is started using "socket
+    activation" with systemd(8), for example.
+  - Implement support for systemd(8) "socket activation".
+  - contrib/README: add description for more files.
+  - Enable WHOIS to display information about IRC Services using the new
+    numeric 310(RPL_WHOISSERVICE) This numeric is used for this purpose by
+    InspIRCd, for example -- but as usual, other numerics are in use, too,
+    like 613 in UltimateIRCd ...
+    Please note that neither the Operator (+o) not the "bot status" (+B)
+    of an IRC service is displayed in the output.
+  - Exit message: use singular & plural :-)
+  - autogen.sh: Check for autoconf/automake wrapper scripts
+  - Add missing punctuation marks in log messages, adjust some severity
+    levels, and make SSL-related messages more readable.
+  - AUTHORS file: Update list of contributors.
+  - Update systemd(8) example configuration files in ./contrib/ directory:
+    the "ngircd.service" file now uses the "forking" service type which
+    enhances the log messages shown by "systemctl status ngircd.service",
+    and the new "ngircd.socket" file configures a systemd socket that
+    configures a socket for ngIRCd and launches the daemon on demand.
+  - Enhance help system and the HELP command: now a "help text file" can be
+    set using the new configuration option "HelpFile" ("global" section),
+    which is read in and parsed on server startup and configuration reload,
+    and then is used to output individual help texts to specific topics.
+    Please see the file ./doc/Commands.txt for details.
+
+ngIRCd 20.3 (2013-08-23)
+
+  - Security: Fix a denial of service bug (server crash) which could happen
+    when the configuration option "NoticeAuth" is enabled (which is NOT the
+    default) and ngIRCd failed to send the "notice auth" messages to new
+    clients connecting to the server (CVE-2013-5580).
+
+ngIRCd 20.2 (2013-02-15)
+
+  - Security: Fix a denial of service bug in the function handling KICK
+    commands that could be used by arbitrary users to to crash the daemon
+    (CVE-2013-1747).
+  - WHO command: Use the currently "displayed hostname" (which can be cloaked!)
+    for hostname matching, not the real one. In other words: don't display all
+    the cloaked users on a specific real hostname!
+  - configure: The header file "netinet/in_systm.h" already is optional in
+    ngIRCd, so don't require it in the configure script. Now ngIRCd can be
+    built on Minix 3 again :-)
+  - Return better "Connection not registered as server link" errors: Now ngIRCd
+    returns a more specific error message for numeric ERR_NOTREGISTERED(451)
+    when a regular user tries to use a command that isn't allowed for users but
+    for servers.
+  - Don't report ERR_NEEDMOREPARAMS(461) when a MDOE command with more modes
+    than nicknames is handled, as well as for channel limit and key changes
+    without specifying the limit or key parameters.
+    This is how a lot (all?) other IRC servers behave, including ircd2.11,
+    InspIRCd, and ircd-seven. And because of clients (tested with Textual and
+    mIRC) sending bogus MODE commands like "MODE -ooo nick", end-users got the
+    expected result as well as correct but misleading error messages ...
+  - Correctly detect when SSL subsystem must be initialized and take
+    outgoing connections (server links!) into account, too.
+  - autogen.sh: Enforce serial test harness on GNU automake >=1.13. The
+    new parallel test harness which is enabled by default starting with
+    automake 1.13 isn't compatible with our test suite.
+    And don't use "egrep -o", instead use "sed", because it isn't portable
+    and not available on OpenBSD, for example.

+ngIRCd 22 (2014-10-11)
+
+  - Match all list patterns case-insensitive: this affects the invite-,
+    ban-, and except lists, as well as G-Lines an K-Lines.
+    Problem pointed out by "wowaname" on #ngircd, thanks!
+
+  ngIRCd 22~rc1 (2014-09-29)
+  - Sync "except lists" between servers: Up to now, ban, invite, and G-Line
+    lists have been synced between servers while linking -- but obviously
+    nobody noticed that except list have been missing ever since. Until now.
+    Thanks to "j4jackj", who reported this issue in #ngircd.
+  - Allow longer user names (up to 63 characters) for authentication.
+  - Increase MAX_SERVERS from 16 to 64: There are installations out there
+    that would like to configure more than 16 links per server, so increase
+    this limit. Best would be to get rid of MAX_SERVERS altogether and make
+    if fully dynamic, but start with this quick and dirty hack ...
+  - Test suite/platformtest.sh: Detect when tests have been skipped.
+  - Allow "DefaultUserModes" to set all possible modes, including modes only
+    settable by IRC Operators.
+  - Implement user mode "F": "relaxed flood protection". Clients with mode
+    "F" set are allowed to rapidly send data to the daemon. This mode is only
+    settable by IRC Operators and can cause problems in the network -- so be
+    careful and only set it on "trusted" clients!
+    User mode "F" is used by Bahamut for this purpose, for example.
+  - Use server password when PAM is compiled in but disabled.
+  - Streamline punctuation of log messages.
+  - Return ISUPPORT(005) numerics on "VERSION". This is how ircd-seven,
+    Charybdis, Hybrid, and InspIRCd behave, for example.
+  - configure: Only link "contrib/Debian" if it exists, which isn't the case
+    on "VPATH builds", for example.
+  - Show the account name in WHOIS. This uses the same numeric as Charybdis
+    and ircu families: WHOISLOGGEDIN(330).
+  - Pattern matching: Remove "range matching" in our pattern matching code
+    using the "[...]" syntax, because [ and ] are valid characters in nick
+    names and one has to quote them currently using the "\" character, which
+    is quite unexpected for users.
+  - platformtest.sh: New option "-x", don't regenerate build system and
+    allow using separate source and build trees.
+  - Test suite: explicitly enable glibc memory checking.
+  - Make "MODE -k" handling more robust and compatible, send "fake '*' key"
+    in all replies.
+  - portabtest: Actually test the functions snprintf(), strlcpy(), strlcat(),
+    and vsnprintf() for correctness, not only existence (which was quite
+    useless, because if they weren't available, the program could not have
+    been linked at all ...).
+  - Implement new configuration option "Network": it is used to set the
+    (completely optional) "network name", to which this instance of the
+    daemon belongs. When set, this name is used in the ISUPPORT(005) numeric
+    which is sent to all clients connecting to the server after logging in.
+  - Update doc/Platforms.txt.
+  - Various code cleanups, remove unused code, streamline error handling.
+    Remove all imp.h and exp.h header files, support non-standard vsnprintf()
+    return codes, and fix some K&R C portability issues. Streamline
+    DEBUG_ARRAY, DEBUG_BUFFER, DEBUG_IO, DEBUG_ZIP definitions.
+  - Increase penalty time to 10 seconds when handling OPER commands with an
+    invalid password.
+
+ngIRCd 21.1 (2014-03-25)
+
+  - Don't ignore but use the server password when PAM is compiled in but
+    disabled. Thanks to Roy Sindre Norangshol <roy.sindre@norangshol.no>!
+  - doc/Platforms.txt: Update from master branch.
+  - doc/Services.txt: Update information for Anope 2.x.
+  - configure: add support for the LDFLAGS_END and LIBS_END variables to add
+    linker flags and libraries at the end of the configure run (CFLAGS_END has
+    been implemented already).
+  - Update Copyright notices for 2014 :-)
+
+ngIRCd 21 (2013-10-30)
+
+  - Call arc4random_stir() in forked subprocesses, when available. This
+    is required by FreeBSD <10 and current NetBSD at least to correctly
+    initialize the "arc4" random number generator on these platforms.
+
+  ngIRCd 21~rc2 (2013-10-20)
+  - Report the correct configuration file name on configuration errors,
+    support longer configuration lines, and warn when lines are truncated.
+
+  ngIRCd 21~rc1 (2013-10-05)
+  - Actually KILL clients on GLINE/KLINE. (Closes bug #156)
+  - Add support to show all user links using the "STATS L" (uppercase)
+    command (restricted to IRC Operators).
+  - Implement configurable SSL cipher list selection for GnuTLS and OpenSSL
+    using the new configuration option "CipherList". In addition, this
+    changes the defaults to more secure values: "HIGH:!aNULL:@STRENGTH" for
+    OpenSSL, and "SECURE128" for GnuTLS.
+  - Show connection flag "s" (SSL) in RPL_TRACE{LINK|SERVER} messages: now
+    you can check if a server-to-server link is SSL-encrypted or not using
+    the IRC "TRACE" command.
+  - Implement the new configuration option "DefaultUserModes" which lists
+    user modes that become automatically set on new local clients right
+    after login. Please note that only modes can be set that the client
+    could set on itself, so you can't set "a" (away) or "o" (IRC Op),
+    for example! User modes "i" (invisible) or "x" (cloaked) etc. are
+    "interesting", though. (Closes bug #160)
+  - Add support for the new METADATA "account" property, which allows
+    services to automatically identify users after netsplits and across
+    service restarts.
+  - Implement a new configuration option "AllowedChannelTypes" that lists
+    all allowed channel types (channel prefixes) for newly created channels
+    on the local server. By default, all supported channel types are allowed.
+    If set to the empty string, local clients can't create new channels at
+    all, which equals the old "PredefChannelsOnly = yes" setting.
+    This change deprecates the "PredefChannelsOnly" variable, too, but it is
+    still supported and translated to the appropriate "AllowedChannelTypes"
+    setting. When the old "PredefChannelsOnly" variable is processed, a
+    warning message is logged. (Closes bug #152)
+  - Add support for "client certificate fingerprinting". When a client
+    passes an SSL certificate to the server, the "fingerprint" will be
+    forwarded in the network which enables IRC services to identify the
+    user using this certificate and not using passwords.
+  - Implement a new configuration option "IncludeDir" in the "[Options]"
+    section that can be used to specify a directory which can contain
+    further configuration files and configuration file snippets matching
+    the pattern "*.conf". These files are read in after the main server
+    configuration file ("ngircd.conf" by default) has been read in and
+    parsed.  The default is "$SYSCONFDIR/ngircd.conf.d", so that it is
+    possible to adjust the configuration only by placing additional files
+    into this directory. (Closes bug #157)
+  - Add Travis-CI configuration file (".travis.yml") to project.
+  - ngIRCd now accepts user names including "@" characters, saves the
+    unmodified name for authentication but stores only the part in front
+    of the "@" character as "IRC user name". And the latter is how
+    ircd2.11, Bahamut, and irc-seven behave as well. (Closes bug #155)
+  - Lots of IRC "information functions" like ADMIN, INFO, ... now accept
+    server masks and names of connected users (in addition to server names)
+    for specifying the target server of the command. (Closes bug #153)
+  - Implement a new configuration option "IdleTimeout" in the "[Limits]"
+    section of the configuration file which can be used to set a timeout
+    in seconds after which the whole daemon will shutdown when no more
+    connections are left active after handling at least one client.
+    The default is 0, "never".
+    This can be useful for testing or when ngIRCd is started using "socket
+    activation" with systemd(8), for example.
+  - Implement support for systemd(8) "socket activation".
+  - Enable WHOIS to display information about IRC Services using the new
+    numeric 310(RPL_WHOISSERVICE) This numeric is used for this purpose by
+    InspIRCd, for example -- but as usual, other numerics are in use, too,
+    like 613 in UltimateIRCd ...
+    Please note that neither the Operator (+o) not the "bot status" (+B)
+    of an IRC service is displayed in the output.
+  - Update systemd(8) example configuration files in ./contrib/ directory:
+    the "ngircd.service" file now uses the "forking" service type which
+    enhances the log messages shown by "systemctl status ngircd.service",
+    and the new "ngircd.socket" file configures a systemd socket that
+    configures a socket for ngIRCd and launches the daemon on demand.
+  - Enhance help system and the HELP command: now a "help text file" can be
+    set using the new configuration option "HelpFile" ("global" section),
+    which is read in and parsed on server startup and configuration reload,
+    and then is used to output individual help texts to specific topics.
+    Please see the file ./doc/Commands.txt for details.

+
+
+This file lists all commands available on ngIRCd. It is written in a format
+that is human readable as well as machine parseable and therefore can be used
+as "help text file" of the daemon.
+
+In short, the daemon reads this file on startup and parses it as following
+when an user issues a "HELP <cmd>" command:
+
+ 1. Search the file for a line "- <cmd>",
+ 2. Output all subsequent lines that start with a TAB (ASCII 9) character
+    to the client using NOTICE commands, treat lines containing a single "."
+    after the TAB as empty lines.
+ 3. Break at the first line not starting with a TAB character.
+
+This format allows to have information to each command stored in this file
+which will not be sent to an IRC user requesting help which enables us to
+have additional annotations stored here which further describe the origin,
+implementation details, or limits of the specific command which are not
+relevant to an end-user but administrators and developers.
+
+A special "Intro" block is returned to the user when the HELP command is
+used without a command name:
+
+
+- Intro
+	This is ngIRCd, a server software for Internet Relay Chat (IRC)
+	networks. You can find more information about ngIRCd on its homepage:
+		<http://ngircd.barton.de>
+	.
+	Use "HELP COMMANDS" to get a list of all available commands and
+	"HELP <command-name>" to get help for a specific IRC command, for
+	example "HELP quit" or "HELP privmsg".
+
+
+Connection Handling Commands
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- CAP
+	CAP LS
+	CAP LIST
+	CAP REQ <capabilities>
+	CAP ACK <capabilities>
+	CAP NAK <capabilities>
+	CAP CLEAR
+	CAP END
+	.
+	List, request, and clear "IRC Capabilities".
+	.
+	Using this command, an IRC client can request additional "IRC
+	capabilities" during login or later on, which influences the
+	communication between server and client. Normally, these commands
+	aren't directly used by humans, but automatically by their client
+	software. And please note that issuing such commands manually can
+	irritate the client software used, because of the "non-standard"
+	behavior of the server!
+	.
+	- CAP LS: list all available capabilities.
+	- CAP LIST: list active capabilities of this connection.
+	- CAP REQ: Request particular capabilities.
+	- CAP ACK: Acknowledge a set of capabilities to be enabled/disabled.
+	- CAP NAK: Reject a set of capabilities.
+	- CAP CLEAR: Clear all set capabilities.
+	- CAP END: Indicate end of capability negotiation during login,
+	  ignored in an fully registered session.
+
+	Please note that the <capabilities> must be given in a single
+	parameter but whitespace separated, therefore a command could look
+	like this: "CAP REQ :capability1 capability2 capability3" for example.
+
+	References:
+	 - <http://ircv3.atheme.org/specification/capability-negotiation-3.1>
+	 - <http://ngircd.barton.de/doc/Capabilities.txt>
+	 - doc/Capabilities.txt
+
+- CHARCONV
+	CHARCONV <client-charset>
+	.
+	Set client character set encoding to <client-charset>.
+	.
+	After receiving such a command, the server translates all message
+	data received from the client using the set <client-charset> to the
+	server encoding (UTF-8), and all message data which is to be sent to
+	the client from the server encoding (UTF-8) to <client-charset>.
+	.
+	This enables older clients and clients using "strange" character sets
+	to transparently participate in channels and direct messages to
+	clients using UTF-8, which should be the default today.
+
+	References:
+	 - IRC+, <http://ngircd.barton.de/doc/Protocol.txt>
+	 - IRC+, doc/Protocol.txt
+
+- NICK
+	NICK <nickname>
+	NICK <nickname> [<hops>]
+	NICK <nickname> <hops> <username> <host> <servertoken> <usermodes> <realname>
+	.
+	Set or change the <nickname> of a client (first form) and register
+	remote clients (second and third form; servers only).
+
+	References:
+	 - RFC 1459, 4.1.2 "Nick message" (old client and server protocol)
+	 - RFC 2812, 3.1.2 "Nick message" (client protocol)
+	 - RFC 2813, 4.1.3 "Nick" (server protocol)
+
+- PASS
+	PASS <password>
+	PASS <password> <version> <flags> [<options>]
+	.
+	Set a connection <password>. This command must be the first command
+	sent to the server, even before the NICK/USER or SERVER commands.
+	.
+	The first form is used by user sessions or (old) RFC 1459 servers,
+	the second form is used by RFC 2812 or IRC+ compliant servers and
+	enables the server to indicate its version and supported protocol
+	features.
+
+	References:
+	 - RFC 1459, 4.1.1 "Password message" (old client and server protocol)

+
+- PING
+	PING <token> [<target>]
+	.
+	Tests the presence of a connection to a client or server.
+	.
+	If no <target> has been given, the local server is used. User clients
+	can only use other servers as <target>, no user clients.
+	.
+	A PING message results in a PONG reply containing the <token>, which
+	can be arbitrary text.
+
+	Please note:
+	The RFCs state that the <token> parameter is used to specify the
+	origin of the PING command when forwarded in the network, but this
+	is not the case: the sender is specified using the prefix as usual,
+	and the parameter is used to identify the PONG reply in practice.
+
+	References:
+	 - RFC 2812, 3.7.2 "Ping message"
+
+- PONG
+	PONG <target> [<token>]
+	.
+	Reply to a "PING" command, indicate that the connection is alive.
+	.
+	The <token> is the arbitrary text received in the "PING" command and
+	can be used to identify the correct PONG sent as answer.
+	.
+	When the "PONG" command is received from a user session, the <target>
+	parameter is ignored; otherwise the PONG is forwarded to this client.
+
+	References:
+	 - RFC 2812, 3.7.3 "Pong message"
+
+- QUIT
+	QUIT [<quit-message>]
+	.
+	Terminate a user session.
+	.
+	When received from a user, the server acknowledges this by sending
+	an "ERROR" message back to the client and terminates the connection.
+	.
+	When a <quit-message> has been given, it is sent to all the channels
+	that the client is a member of when leaving.
+
+	References:
+	 - RFC 2812, 3.1.7 "Quit"
+	 - RFC 2813, 4.1.5 "Quit"
+
+- USER
+	USER <username> <hostname> <unused> <realname>
+	.
+	Register (and authenticate) a new user session with a short <username>
+	and a human-readable <realname>.
+	.
+	The parameter <hostname> is only used when received by an other server
+	and ignored otherwise; and the parameter <unused> is always ignored.
+	But both parameters are required on each invocation by the protocol
+	and can be set to arbitrary characters/text when not used.
+	.
+	If <username> contains an "@" character, the full <username> is used
+	for authentication, but only the first part up to this character is
+	set as "user name" for this session.
+
+	References:
+	 - RFC 2812, 3.1.3 "User message"
+
+- WEBIRC
+	WEBIRC <password> <username> <hostname> <ip-address>
+	.
+	Allow Web-to-IRC gateway software (for example) to set the correct
+	user name and host name of users instead of their own.
+	.
+	It must be the very first command sent to the server, even before
+	USER and NICK commands!
+	.
+	The <password> must be set in the server configuration file to prevent
+	unauthorized clients to fake their identity; it is an arbitrary string.

+
+General Commands
+~~~~~~~~~~~~~~~~
+
+- AWAY
+	AWAY [<message>]
+	.
+	Provides the server with a message to automatically send in reply to a
+	PRIVMSG directed at the user, but not to a channel they are on.
+	.
+	If <message> is omitted, the away status is removed.
+
+	References:
+	 - RFC 2812, 4.1 "Away"
+
+- HELP
+	HELP [<command>]
+	.
+	Show help information for a specific IRC <command>. The <command> name
+	is case-insensitive.
+	.
+	Use the command "HELP Commands" to get a list of all available commands.
+
+	The HELP command isn't specified by any RFC but implemented by most
+	daemons. If no help text could be read in, ngIRCd outputs a list of all
+	implemented commands when receiving a plain "HELP" command as well as
+	on "HELP Commands".
+
+	ngIRCd replies using "NOTICE" commands like ircd 2.10/2.11; other
+	implementations are using numerics 704, 705, and 706.
+
+- MODE
+	MODE <nickname> [{+|-}<mode>[<mode>] [{+|-}<mode>[<mode>] [...]]]
+	MODE <channel> [{+|-}<mode>[<mode>] [<arg> [<arg> [...]]] [{+|-}<mode>[<mode>] [<arg> [<arg> [...]]] [...]]]
+	.
+	Set and get user and channel modes.
+	.
+	When no mode parameters are given, the currently set user or channel
+	modes are returned. Otherwise the modes are adjusted accordingly
+	and the changes will be reported back to the client.
+	.
+	All user and channel "modes" are indicated by single case-sensitive
+	characters.
+	.
+	Please note that a user can only get and set his own modes, and not
+	all user "levels" are allowed to change all channel modes ...
+	.
+	The mode parameters can become quite complex, especially when dealing
+	with channel modes that require additional arguments:
+	.
+	  {+|-}<mode(s}>  -- set or unset one or more modes.
+	  +<mode(s)> -<mode(s)>  -- set some modes and unset others.
+	  +<modes> <arg1> <arg2>  -- set (at least) two modes with arguments.
+	.
+	Some examples:
+	.
+	  MODE nick +i  -- set user to "invisible".
+	  MODE #chan +tn  -- set "topic lock" and "no external messages".
+	  MODE #chan -t +l 50  -- remove "topic lock", set "user limit" to 50.
+	  MODE #chan +ov nick1 nick2  -- set "channel op" and "voice" mode
+	                                 to nick1 and nick2 in channel #chan.
+	.
+	A complete list of all modes supported by ngIRCd can be found online
+	here: <http://ngircd.barton.de/doc/Modes.txt>.

+	 - doc/Modes.txt
+
+- NOTICE
+	NOTICE <target>[,<target>[,...]] <message>
+	.
+	Send a <message> to a given <target>, which can be a user or a
+	channel, but DON'T report any error.
+	.
+	The "NOTICE" command exactly behaves like the "PRIVMSG" command, but
+	doesn't report any errors it encounters (like an unknown <target>).
+	Please see the help text of the "PRIVMSG" command for a detailed
+	description of the parameters!
+
+	References:
+	 - RFC 2812, 2.3.1 "Message format in Augmented BNF"
+	 - RFC 2812, 3.3 "Sending messages"
+	 - RFC 2812, 3.3.2 "Notice"
+
+- PRIVMSG
+	PRIVMSG <target>[,<target>[,...]] <message>
+	.
+	Send a <message> to a given <target>, which can be a user or a
+	channel, and report all errors.
+	.
+	The <target> must follow one of these syntax variants:
+	.
+	 - <nickname>
+	 - <channel>
+	 - <user>[%<host>]@<server>
+	 - <user>%<host>
+	 - <nickname>!<user>@<host>
+	.
+	If the <target> is a user, a private message is sent directly to this
+	user; if it resolves to a channel name, a public message is sent
+	to all the members of that channel.
+	.
+	In addition, IRC Ops can use these two forms to specify the <target>:
+	.
+	 - #<hostmask>
+	 - #<servermask>
+	.
+	The <mask> can contain the wildcard characters "*" and "?", but must
+	contain at least one dot (".") and no wildcard after the last one.
+	Then, the <message> is sent to all users matching this <mask>.
+	.
+	All warnings and errors are reported back to the initiator using
+	numeric status codes, which is the only difference to the "NOTICE"
+	command, which doesn't report back any errors or warnings at all.
+	.
+	Please note that clients often use "MSG" as an alias to PRIVMSG, and
+	a command "QUERY <nick> [<message>]" to initiate private chats. Both
+	are command extensions of the client and never sent to the server.

+	Show administrative information about an IRC server in the network.
+	.
+	<target> can be a server name, the nickname of a client connected to
+	a specific server, or a mask matching a server name in the network.
+	The server of the current connection is used when <target> is omitted.
+
+	References:
+	 - RFC 2812, 3.4.9 "Admin command"
+
+- INFO
+	INFO [<target>]
+	.
+	Show the version, birth & online time of an IRC server in the network.

+	a list only containing nicknames actually connected to a server in
+	the network. If no nicknames of the given list are online, an empty
+	list is returned to the client requesting the information.
+
+	Please note that "all" IRC daemons even parse separate nicknames in
+	a single parameter (like ":nick1 nick2"), and therefore ngIRCd
+	implements this behaviour, too.

+
+- LINKS
+	LINKS [[<target>] [<mask>]
+	.
+	List all servers currently registered in the network matching <mask>,

+	seen by the server <target>. More than one <channel> can be given
+	separated by "," (but not whitespaces!).
+	.
+	If <channel> has been omitted, all visible users are shown, grouped
+	by channel name, and all visible users not being members of at least
+	one channel are shown as members of the pseudo channel "*".
+	.

+	.
+	The following <query> types are supported (case-insensitive where
+	applicable):
+	.
+	 - g  Network-wide bans ("G-Lines").

+
+- TRACE
+	TRACE [<target>]
+	.
+	Find the route to a specific server and send information about its
+	peers. Each server that processes this command reports back to the
+	sender about it: the replies from pass-through servers form a chain
+	which shows the route to the destination.
+	.
+	<target> can be a server name, the nickname of a client connected to
+	a specific server, or a mask matching a server name in the network.
+	The server of the current connection is used when <target> is omitted.

+	 - RFC 2812, 3.4.3 "Version message"
+
+- WHO
+	WHO [<mask> ["o"]]
+	.

+Channel Commands
+~~~~~~~~~~~~~~~~
+
+- INVITE
+	INVITE <nickname> <channel>
+	.
+	Invite <nickname> to join channel <channel>.
+	.
+	<channel> does not have to exist, but if it does, only members of the
+	channel are allowed to invite other users. If the channel mode "+i"
+	is set, only channel "half-ops" (and above) may invite other clients,
+	and if channel mode "+V" is set, nobody can invite other users.

+- JOIN
+	JOIN {<channel>[,<channel>[,...]] [<key>[,<key>[,...]]] | 0}
+	.

+- TOPIC
+	TOPIC <channel> [<topic>]
+	.
+	Change or view the topic of a channel.
+	.
+	The topic for channel <channel> is returned if there is no <topic>
+	given. If the <topic> parameter is present, the topic for that

+	a connection on a <remote-server>, you must have remote IRC operator
+	privileges.
+	.
+	If <port>, <my-pwd> and <peer-pwd> are given, these values override
+	the ones specified in the server configuration file.

+	To use this command, the user must be an IRC Operator.
+	.
+	"STATS k" can be used to list all currently active K-Lines.
+
+	References:

+	   of ngIRCd.
+
+- OPER
+	OPER <name> <password>
+	.
+	Authenticates a user named <name> as an IRC operator on the current
+	server/network.
+	.
+	This operator <name> must be configured in the server configuration.

+
+	References:
+	 - RFC 2812, 3.1.4 "Oper message"
+
+- REHASH

+
+IRC Service Commands
+~~~~~~~~~~~~~~~~~~~~
+
+- SERVICE
+	SERVICE <name> <reserved1> <distribution> <type> <reserved2> <info>
+	SERVICE <name> <servertoken> <distribution> {<type>|+<modes>} <hops> <info>
+	.
+	Register a new service in the network.
+	.
+	The first form is used by directly linked services and isn't supported
+	by ngIRCd at the moment. The second form announces services connected
+	to remote "pseudo-servers" ("services hubs").
+	.
+	The <distribution> and <type> parameters are ignored by ngIRCd.
+
+	References:
+	 - RFC 2812, 3.1.6 "Service message"
+	 - RFC 2813, 4.1.4 "Service message"
+
+- SERVLIST
+	SERVLIST [<mask> [<type>]]
+	.
+	List all IRC services currently registered in the network.
+	.
+	The optional <mask> and <type> parameters can be used to limit the
+	listing to services matching the <mask> and that are of type <type>.
+	.
+	Please note that ngIRCd doesn't use any service types at the moment
+	and therefore all services are of type "0".
+
+	References:
+	 - RFC 2812, 3.5.1 "Servlist message"
+
+- SQUERY
+	SQUERY <target>[,<target>[,...]] <message>
+	.
+	Send a <message> to a given <target> IRC service, and report all
+	errors.
+	.
+	The "SQUERY" command exactly behaves like the "PRIVMSG" command, but
+	enforces that the <target> of the <message> is an IRC service.
+	Please see the help text of the "PRIVMSG" command for a detailed
+	description of the parameters!
+	.
+	If a user wants to interact with IRC services, he should use "SQUERY"
+	instead of "PRIVMSG" or "NOTICE": only "SQUERY makes sure that no
+	regular user, which uses the nickname of an IRC service, receives
+	the command in error, for example during a "net split"!
+
+	References:
+	 - RFC 2812, 2.3.1 "Message format in Augmented BNF"
+	 - RFC 2812, 3.3 "Sending messages"
+	 - RFC 2812, 3.3.2 "Notice"
+
+- SVSNICK
+	SVSNICK <oldnick> <newnick>
+	.
+	Forcefully change foreign user nicknames. This command is allowed
+	for servers only.
+	.
+	The "SVSNICK" command is forwarded to the server to which the user
+	with nickname <oldnick> is connected to, which in turn generates a
+	regular "NICK" command that then is sent to the client, so no special
+	support in the client software is required.

+
+
+Server Protocol Commands
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+- CHANINFO
+	CHANINFO <channel> +<modes> [[<key> <limit>] <topic>]
+	.
+	CHANINFO is used by servers to inform each other about a channel:
+	its modes, channel key, user limits and its topic.
+	.
+	The CHANINFO command is allowed on server-links only.
+
+	References:
+	 - IRC+, <http://ngircd.barton.de/doc/Protocol.txt>
+	 - IRC+, doc/Protocol.txt
+
+- ERROR
+	ERROR [<message> [<> [...]]]
+	.
+	Inform a client or a server about an error condition. The first 
+	parameter, if given, is logged by the server receiving the message,
+	all other parameters are silently ignored.
+	.
+	This command is silently ignored on non-server and non-service links
+	and shouldn't be used by regular IRC clients.
+	.
+	The ERROR message is also sent before terminating a regular client
+	connection.
+
+	References:
+	 - RFC 2812, 3.7.4 "Error message"
+
+- METADATA
+	METADATA <target> <key> <value>
+	.
+	The METADATA command is used on server-links to update "metadata"
+	information of clients, like the hostname, the info text ("real name"),
+	or the user name.
+	.
+	The METADATA command is allowed on server-links only.
+
+	References:
+	 - IRC+, <http://ngircd.barton.de/doc/Protocol.txt>
+	 - IRC+, doc/Protocol.txt
+
+- NJOIN
+	NJOIN <channel> [<mode>]<nick>[,[<mode>]<nick>[,...]]
+	.
+	The NJOIN command is used on server-links to add users with <nick>
+	and <mode> to a <channel> while peering.
+	.
+	The NJOIN command is allowed on server-links only.
+
+	References:
+	 - RFC 2813, 4.2.2 "Njoin message"
+
+- SERVER
+	SERVER <servername> <info>
+	SERVER <servername> <hopcount> <info>
+	SERVER <servername> <hopcount> <token> <info>
+	.
+	The first form registers the local connection as a new server in the
+	network, the second (RFC 1459) and third (RFC 2812) form announce a
+	new remote server in the network.
+	.
+	The SERVER command is allowed on unregistered or server-links only.
+
+	References:
+	 - RFC 1459, 4.1.4 "Server message"
+	 - RFC 2813, 4.1.2 "Server message"
+
+- SQUIT
+	SQUIT <server> <comment>
+	.
+	Disconnects an IRC Server from the network.
+	.
+	This command is used on server-links, but can be used by IRC Operators
+	to forcefully disconnect servers from the network, too.
+
+	References:
+	 - RFC 2812, 3.1.8 "Squit"
+	 - RFC 2813, 4.1.6 "Server quit message"
+
+Dummy Commands
+~~~~~~~~~~~~~~
+
+- SUMMON
+	SUMMON <user> [<target> [<channel>]]
+	.
+	This command was intended to call people into IRC who are directly
+	connected to the terminal console of the IRC server -- but is
+	deprecated today. Therefore ngIRCd doesn't really implement this
+	command and always returns an error message, regardless of the
+	parameters given.
+
+	References:
+	 - RFC 2812, 4.5 "Summon message"
+
+- USERS
+	USERS [<target>]
+	.
+	This command was intended to list users directly logged in into the
+	console of the IRC server -- but is deprecated today. Therefore ngIRCd
+	doesn't really implement this command and always returns an error
+	message, regardless of the parameters given.
+
+	References:
+	 - RFC 2812, 4.6 "Users"
+
+- GET
+	GET [...]
+	.
+	Fake HTTP GET command. When received, the connection is shut down
+	immediately again to protect against crazy web browsers ...
+
+	References:
+	 - ngIRCd GIT commit 33e8c2480649
