+ngIRCd Release 19 (2012-02-29)
+
+  - Update build system: bump config.guess and config.sub files used by
+    GNU autoconf/automake to recent versions.
+  - Fix configuration file parser: don't accept "[SSL]" blocks in the
+    configuration file when no SSL support is built in ngIRCd.
+  - Fix building ngIRCd with old gcc versions (e. g. 2.7.2).
+  - Correctly re-open syslog logging after reading of configuration
+    file: Syslog logging has been initialized before reading the
+    configuraton, so ngIRCd always used the default facility and ignored
+    the "SyslogFacility" configuration option ...
+    Thanks to Patrik Schindler for reporting this issue!
+
+  ngIRCd 19~rc1 (2012-02-12)
+  - Enhance command limits for server links: the limit now is dependent
+    on the number of users connected in the network and higher while
+    servers are joining the network to make the login of servers faster.
+  - Log more information about server synchronization.
+  - Update preliminary ngIRCd protocol module for Anope 1.9.6, which now
+    is the only supported version.
+  - New numeric RPL_WHOISHOST_MSG(378), which returns the DNS hostname
+    (if available) and the IP address of a client in the WHOIS reply.
+    Only the user itself and local IRC operators get this numeric.
+  - Implement channel exception list (mode 'e'). This allows a channel
+    operator to define exception masks that allow users to join the
+    channel even when a "ban" would match and prevent them from joining:
+    the exception list (e) overrides the ban list (b).
+  - PRIVMSG and NOTICE: Handle nick!user@host masks case-insensitive.
+  - Implement user mode 'C': If the target user of a PRIVMSG or NOTICE
+    command has the user mode 'C' set, it is required that both sender
+    and receiver are on the same channel. This prevents private flooding
+    by completely unknown clients.
+  - New RPL_WHOISREGNICK_MSG(307) numeric in WHOIS command replies: it
+    indicates if a nick name is registered (if user mode 'R' set).
+  - Limit channel invite, ban, and exception lists to 50 entries and fix
+    duplicate check and error messages when adding already listed entries
+    or deleting no (longer) existing ones.
+  - Fix both ERR_SUMMONDISABLED(445) and ERR_USERSDISABLED(446) replies.
+  - MODE command: correctly return ERR_UNKNOWNMODE(472) numeric for
+    unknown channel modes, instead of ERR_UMODEUNKNOWNFLAG(501).
+  - ISUPPORT(005) numeric: add "O", "R", and "z" modes to "CHANMODES",
+    add "EXCEPTS=e" and "INVEX=I", add "MAXLIST=beI:50".
+  - Limit the number of list items in the reply of LIST (100), WHO (25),
+    WHOIS (10), and WHOWAS (25) commands.
+  - LIST command: compare pattern case insensitive.
+  - Limit the MODE command to handle a maximum number of 5 channel modes
+    that require an argument (+Ibkl) per call and report this number
+    in the ISUPPORT(005) numeric: "MODES=5".
+  - Fix handling of channel mode sequence with/without arguments.
+    For example, don't generate wrong error messages when handling
+    "MODE #chan +IIIIItn *!aa@b *!bb@c *!cc@d *!dd@e *!ee@f".
+  - When sending data on a connection, only try to get the type of
+    the client if there still is one assigned. This could trigger an
+    assertion and end the daemon in some error paths.
+  - Don't try to close already closed/invalid sockets to forked child
+    processes. This could potentially crash the daemon in some cases
+    with IDENT lookups enabled.
+  - WHOIS command: make sure that the reply ends with RPL_ENDOFWHOIS,
+    don't answer queries for IRC servers, make sure mask matching is
+    case-insensitive, and that RPL_ENDOFWHOIS numeric is sent with the
+    unmodified mask (like it has been received from the client).
+  - LINKS command: support <mask> parameter to limit the reply.
+  - Add 1 second penalty for every further target on PRIVMSG/NOTICE
+    commands: this reduces the possibility of flooding channels with
+    commands like "PRIVMSG/NOTICE #a,#n,#c,... :message" a little bit.
+    Problem noticed by Cahata, thanks!
+  - Display correct error message when "Server{UID|GID}" variabe in the
+    configuration file is invalid (not a number and no existing user).
+  - Update Copyright notices for 2012 :-)
+  - JOIN command: don't stop handling of channel lists when a single
+    channel cannot be joined (because of bad name, wrong key or channel
+    limit reached), but report an error and continue. And don't check
+    the channel limit and don't report with "too many channels" when
+    trying to join a channel that the client already is a member of.
+  - ISON command: reply with the correct upper-/lowercase nick names.
+  - New configuration option "PAMIsOptional": when set, clients not
+    sending a password are still allowed to connect: they won't become
+    "identified" and keep the "~" character prepended to their supplied
+    user name. See "man 5 ngircd.conf" for details.
+  - Fixed handling of WHO commands. This fixes two bugs: "WHO <nick>"
+    returned nothing at all if the user was "+i" (reported by Cahata,
+    thanks) and "WHO <nick|nickmask>" returned channel names instead
+    of "*" when the user was member of a (visible) channel.
+  - Fixed some spelling errors in documentation and code comments
+    (Thanks to Christoph Biedl).
+  - contrib/Debian/control: Update and complete "Build-Depends" and
+    update our Debian package descriptions with "official" ones.
+  - Fixed typo in two error messages.
+  - LUSERS reply: only count channels that are visible to the requesting
+    client, so the existence of secret channels is no longer revealed by
+    using LUSERS. Reported by Cahata, thanks!
+  - Unknown user and channel modes no longer stop the mode parser, but
+    are simply ignored. Therefore modes after the unknown one are now
+    handled. This is how ircd2.10/ircd2.11/ircd-seven behave, at least.
+    Reported by Cahata, thanks!
+  - README: Update list of implemented commands.
+  - Log better error messages when rejecting clients.
+  - Implement IRC commands "GLINE" and "KLINE" to ban users. G-Lines are
+    synchronized between server on peering, K-Lines are local only.
+    If you use "*!<user>@<host>" or "*!*@<host>" masks, these connections
+    are blocked even before the user is fully logged in (before PASS,
+    NICK, and USER commands have been processed) and before the child
+    processes for authentication are forked, so resource usage is smaller.
+  - Xcode: update project file for Xcode 4.2 and define HAVE_GAI_STRERROR
+    for Mac OS X Xcode builds.
+  - ./configure: Fix logic and quoting of poll() detection code: only use
+    poll() when poll.h exists as well.
+  - Suppress 'Can't create pre-defined channel: invalid name: ""' message.
+  - whois-test: handle local hostname = "localhost.localdomain" using the
+    pattern "localhost*" for valid local hostnames.
+  - sample-ngircd.conf: show correct default for "PAM" variable: The
+    default of "PAM" is "yes" when ngIRCd has been configured to use it,
+    so show the correct default value in the sample configuration file.
+    (Closes #119)
+  - Update GPL 2 license text to current version.
+  - Only close "unrelated" sockets in forked child processes: This fixes
+    the problem that ngIRCd can't do any IDENT lookups because of the
+    socket has already been closed in the child process.
+    The bug has been introduced starting with ngIRCd 17 ... :-(
+    (commit ID 6ebb31ab35e)
+  - Added doc/Modes.txt: document modes supported by ngIRCd.
+  - Implement user mode "R": indicates that the nick name of this user
+    is "registered". This mode isn't handled by ngIRCd itself, but must
+    be set and unset by IRC services like Anope.
+  - Implement channel mode "R": only registered users (having the user
+    mode "R" set) are allowed to join this channel.
+  - Test suite: bind to loopback (127.0.0.1) interface only.
+  - New 2nd message "Nickname too long" for error code 432.
+  - Xcode: Mac OS X config.h: support 10.5 as well as 10.6/10.7 SDK.
+  - Xcode: exclude more Xcode 4 specific directories in ".gitignore".
+  - Disconnect directly linked servers sending QUIT. Without this,
+    the server becomes removed from the network and the client list,
+    but the connection isn't shut down at all ...
+  - contrib/ngindent: detect "gindent" as GNU indent.
+  - Handle unknown user and channel modes: these modes are saved and
+    forwarded to other servers, but ignored otherwise.
+  - Handle channel user modes 'a', 'h', and 'q' from remote servers.
+    These channel user modes aren't used for anything at the moment,
+    but ngIRCd knows that these three modes are "channel user modes"
+    and not "channel modes", that is that these modes take an "nick name"
+    argument. Like unknown user and channel modes, these modes are saved
+    and forwarded to other servers, but ignored otherwise.
+  - Correctly inform clients when other servers change their user modes.
+    This is required for some services to work correctly.
+  - Test suite: make getpid.sh work even when run as root.
+  - Spoofed prefixes: close connection on non-server links only.
+    On server-links, spoofed prefixes can happen because of the
+    asynchronous nature of the IRC protocol. So don't break server-
+    links, only log a message and ignore the command. (Closes #113)

  at the "ngircd-full" package if you need advanced functionality like support
  for IPv6 or SSL.

- Advantages of ngIRCd:
-  - no problems with servers using changing/non-static IP addresses.
-  - small and lean configuration file.
-  - free, modern and open source C code.
-  - still under active development.

- ngIRCd is compatible to the "original" ircd 2.10.3p3, so you can run

 %description
-ngIRCd is a free open source daemon for the Internet Relay Chat (IRC),
-developed under the GNU General Public License (GPL). It's written from
-scratch and is not based upon the original IRCd like many others.
+This package provides ngIRCd, a lightweight Internet Relay Chat
+server for small or private networks. It is simple to configure, can
+cope with dynamic IP addresses, and supports IPv6 as well as SSL. It
+is written from scratch, not based on the original IRCd and quite
+portable.
 
 Advantages:
- - no problems with servers using changing/non-static IP addresses.
- - small and lean configuration file.
- - free, modern and open source C code.
- - still under active development.
-
-ngIRCd is compatible to the "original" ircd 2.10.3p3, so you can run
-mixed networks.
+ - well arranged (lean) configuration file
+ - simple to build/install, configure and maintain
+ - supports IPv6 and SSL
+ - no problems with servers that have dynamic IP addresses
+ - freely available, modern, portable and tidy C-source
+ - ngIRCd is being actively developed since 11 years.

+
+This document lists the different user modes, channel modes, and channel
+user modes that ngIRCd supports.
+
+
+I. User Modes
+~~~~~~~~~~~~~
+
+User modes are attributes a user has in the network, regardless of the
+channels he is using at the moment.
+
+  mode	since	description
+
+  a	0.3.0	User is away.
+  c	17	IRC operator wants to receive connect/disconnect NOTICEs.
+  C	19	Only users that share a channel are allowed to send messages.
+  i	0.0.1	User is "invisible".
+  o	0.0.1	User is IRC operator.
+  r	0.0.1	User is restricted.
+  R (1)	19	User is registered (e.g. by NickServ).
+  s	0.4.0	User wants to receive server notices.
+  w	0.11.0	User wants to receive WALLOPS messages.
+  x	17	Hostname of this user is "cloaked".
+
+II. Channel Modes
+~~~~~~~~~~~~~~~~~
+
+Channel modes are attributes of specific channels which are valid for all
+users joined (or trying to join) to this channel. Some modes add and remove
+users to lists (e.g. "invite list", "ban list"), others have parameters
+(like "channel key"), most are simple flags (like "moderated").
+
+  mode	since	description
+
+  b	0.5.0	Add/remove a host mask to the ban list.
+  i	0.5.0	Channel is "invite only".
+  I	0.5.0	Add/remove a host mask to the invite list.
+  k	0.6.0	Channel has a "key" (a password).
+  l	0.6.0	Channel has a user limit.
+  m	0.3.0	Channel is moderated, only "voiced" users can send messages.
+  n	0.3.0	Channel doesn't allow messages of users not being members.
+  O	18	Only IRC operators are allowed to join this channel.
+  P	0.5.0	Channel is "persistent".
+  r (1)	19	Channel is "registered" (e.g. by ChanServ).
+  R	19	Only registered users are allowed to join this channel.
+  s	0.9.0	Channel is "secret".
+  t	0.3.0	Only ChanOps are allowed to modify the channel topic.
+  z	16	Only users connected via SSL are allowed to join the channel.
+
+III. Channel User Modes
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Channel user modes are attributes that a particular user has in a specific
+channel of which he is a member.
+
+  mode	since	description
+
+  o	0.2.0	User is channel operator and can op/kick/... other members.
+  v	0.2.0	User is "voiced" and can speak even if channel is moderated.
+
+
+Notes
+~~~~~
+
+(1) This mode is not set by ngIRCd itself but by services. ngIRCd handles
+    the mode transparently and possibly adjusts its behaviour.
