-ngIRCd CVSHEAD
+ngIRCd 0.12.1 (2008-07-09)

+    enhanced test suite to check these commands. (Dana Dahlstrom)
+  - RPL_WHOREPLY messages generated by IRC_WHO didn't include flags (*,@,+).
+    (Dana Dahlstrom)
+  - IRC_WHO now supports search patterns and will test this against user
+    nickname/servername/hostname, etc. as required by RFC 2812, Section 3.6.1.
+    (reported by Dana Dahlstrom)
+  - Add test cases for "WHO" command. (Dana Dahlstrom)

+    as if the user had sent PART commands for all channels the user is a
+    member of. (Dana Dahlstrom)
+  - Allow NOTICEs to be sent to a channel. (Fabian Schlager)
+
+ngIRCd 0.11.1 (2008-02-26)

+    mode flags. (Rolf Eike Beer) [from HEAD]
+  - Send "G" instead of "H" flag in WHO replies. (reported by Dana Dahlstrom)

+  - Don't connect to a server if a connection to another server within the
+    same group is already in progress.
+  - Added support for the WALLOPS command. Usage is restricted to IRC
+    operators.

+
+ngIRCd 0.10.1 (2006-12-17)
+
+  - Fixed validation of server names containing digits.
+  - Update the "info text" of the local server after re-reading configuration.
+  - Changed Numerics 265 and 266 to follow ircd 2.11.x "standards".
+  - Allow PASS syntax defined in RFC 1459 for server links, too.
+  - Enhanced ISUPPORT message (005 numeric).
+  - New configuration option "PredefChannelsOnly": if set, clients can only
+    join predefined channels.
+  - Code cleanups: use "LogDebug(...)" instead of "Log(LOG_DEBUG, ...)", use
+    "strcspn()", unsigned vs. signed, use "const", fix whitespaces, ...
+
+ngIRCd 0.10.0 (2006-10-01)
+
+  - Fixed file handle leak when daemon is not able to send MOTD to a client.
+
+  ngIRCd 0.10.0-pre2 (2006-09-09)

+
+  ngIRCd 0.10.0-pre1 (2006-08-02)

+  - Enhanced DIE to accept a single parameter ("comment text") which is sent
+    to all locally connected clients before the server goes down.
+  - The ngIRCd handles time shifts backwards more gracefully now (the
+    timeout handling doesn't disconnect clients by mistake any more).
+  - Internal: Restructured connection handling (the connection ID is equal
+    to the file descriptor of the connection).
+  - Internal: Simplified resolver code.
+  - JOIN now supports more than one channel key at a time.
+  - Implemented numeric "333": Time and user name who set a channel topic.
+  - Enhanced the handler for PING and PONG commands: fix forwarding and enable
+    back-passing of a client supplied additional argument of PING.
+  - Changed handling of timeouts for unregistered connections: don't reset
+    the counter if data is received and disconnect clients earlier.
+  - Removed unnecessary #define of "LOCAL", now use plain C "static" instead.
+  - Channel topics are no longer limited to 127 characters: now the only limit
+    is the maximum length of an IRC command, i. e. 512 bytes (in practice, this
+    limits the topic to about 490 characters due to protocol overhead).
+  - Reverse DNS lookup code now checks the result by doing an additional
+    lookup to prevent spoofing.
+  - Added new IO layer which (optionally) supports epoll() and kqueue() in
+    addition to the select() interface.
+
+ngIRCd 0.9.2 (2005-10-15)
+
+  - Fixed a bug that could cause the daemon to crash when outgoing server
+    connections can't be established.
+  - Fixed a bug that caused the daemon to leak file descriptors when no
+    resolver subprocesses could be created.
+  - Fixed server NOTICEs to users with "s" mode ("server messages").
+  - Fixed a format string bug in "connection statistics" messages to clients.
+
+ngIRCd 0.9.1 (2005-08-03)
+
+  - The KILL command killed much more than desired (including server links!)
+    when the target user is connected to a remote server. Bug introduced in
+    ngIRCd 0.9.0 ...  Reported by <qssl@fastmail.fm>, Thanks!
+  - Changed some constants to be "signed" (instead of unsigned) to solve
+    problems with old (pre-ANSI) compilers.
+
+ngIRCd 0.9.0 (2005-07-24)
+
+  ngIRCd 0.9.0-pre1 (2005-07-09)
+  - Fixed maximum length of user names, now allow up to 9 characters.
+  - Cut off oversized IRC messages that should be sent to the network instead
+    of shutting down the (wrong) connection.
   - Don't generate error messages for unknown commands received before the
     client is registered with the server (like the original ircd).
   - Never run with root privileges but always switch the user ID.

-II. Useful make-targets
+III. Additional features
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+The following optional features can be compiled into the daemon by passing
+options to the "configure" script. Most options can handle a <path> argument
+which will be used to search for the required libraries and header files in
+the given paths ("<path>/lib/...", "<path>/include/...") in addition to the
+standard locations.
+
+* Syslog Logging (autodetected by default): 
+  --with-syslog[=<path>] / --without-syslog
+
+  Enable (disable) support for logging to "syslog", which should be
+  available on most modern UNIX-like operating systems by default.
+
+* ZLib Compression (autodetected by default):
+  --with-zlib[=<path>] / --without-zlib
+
+  Enable (disable) support for compressed server-server links.
+  The Z compression library ("libz") is required for this option.
+  
+* IO Backend (autodetected by default):
+  --with-select[=<path>] / --without-select
+  --with-poll[=<path>] / --without-poll
+  --with-devpoll[=<path>] / --without-devpoll
+  --with-epoll[=<path>] / --without-epoll
+  --with-kqueue[=<path>] / --without-kqueue  
+
+  ngIRCd can use different IO "backends": the "old school" select() and poll()
+  API which should be supported by most UNIX-like operating systems, or the
+  more efficient and flexible epoll() (Linux >=2.6), kqueue() (BSD) and
+  /dev/poll APIs.
+  By default the IO backend is autodetected, but you can use "--without-xxx"
+  to disable a more enhanced API.
+  When using the epoll() API, support for select() is compiled in as well by
+  default to enable the binary to run on older Linux kernels (<2.6), too.
+
+* IDENT-Support:
+  --with-ident[=<path>]
+
+  Include support for IDENT ("AUTH") lookups. The "ident" library is
+  required for this option.
+
+* ZeroConf Support:
+  --with-zeroconf[=<path>] 
+
+  Compile ngIRCd with support for ZeroConf multicast DNS service registration.
+  Either the Apple ZeroConf implementation (e. g. Mac OS X) or the Howl
+  library is required. Which one is available is autodetected.
+
+* TCP-Wrappers:
+  --with-tcp-wrappers[=<path>] 
+
+  Include support for Wietse Venemas "TCP Wrappers" to limit client access
+  to the daemon, for example by using "/etc/hosts.{allow|deny}".
+  The "libwrap" is required for this option.

-I. Anonymous read-only Access
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-To access the source tree anonymously in read-only mode, follow these steps:
-
-Login to the CVS server:
-
- $ cvs -d:pserver:anonymous@arthur.ath.cx:/usr/local/CVS/ngircd login
-
-Use "anonymous" as user name and no password (just hit Return). Now you can
-check out the sources:
-
- $ cvs -d:pserver:anonymous@arthur.ath.cx:/usr/local/CVS/ngircd checkout ngircd
-
-Thereby a new folder "ngircd" will be created containing all the individual
-source files.
-
-This is the "working folder", all CVS commands will be executed from within
-this folder in the future.
-
-Please note: When checking out a fresh copy of ngIRCd from CVS, 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.
-
-Updating the CVS tree:
-
- $ cvs update -d -P [<filename>]
-
-You can update a single file or the complete source tree.

-
-III. Write Access
-~~~~~~~~~~~~~~~~~
-If you want to contribute a couple of patches and write access to the CVS
-repository would be handy, please contact Alex Barton, <alex@barton.de>.

+extension, which is indicated by the 'H' flag in the <serverflags> sent with
+the PASS command, see section II.1.
+
+It basically means, that after exchanging the PASS and SERVER commands the
+server is not registered in the network (as usual), but that IRC numerics
+are exchanged until the numeric 376 (ENDOFMOTD) is received. Afterwards the
+peer is registered in the network as with the regular IRC protocol.
+
+A server implementing the enhanced server handshake (and indicating this
+using 'H' in the <serverflags>) MUST ignore all unknown numerics to it
+silently.
+
+In addition, such a server should at least send the numeric 005 (ISUPPORT)
+to its peer, containing the following information. Syntax: <key>=<value>,
+one token per IRC parameter. If the server has to send more than 12 token
+it must send separate ISUPPORT numerics (this is a limitation of the IRC
+protocol which allows at max 15 arguments per command).
+
+ - NICKLEN: Maximum nickname length. Default: 9.
+ - CASEMAPPING: Case mapping used for nick- and channel name comparing.
+   Default: "ascii", the chars [a-z] are lowercase of [A-Z].
+ - PREFIX: List of channel modes a person can get and the respective prefix
+   a channel or nickname will get in case the person has it. The order of the
+   modes goes from most powerful to least powerful. Default: "(ov)@+"
+ - CHANTYPES: Supported channel prefixes. Default: "#".
+ - CHANMODES: List of channel modes for 4 types, separated by comma (","):
+   Mode that adds or removes a nick or address to a list, mode that changes
+   a setting (both have always has a parameter), mode that changes a setting
+   and only has a parameter when set, and mode that changes a setting and
+   never has a parameter. For example "bI,k,l,imnPst".
+ - CHANLIMIT: Maximum number of channels allowed to join by channel prefix,
+   for example "#:10".
+
+Please see <http://www.irc.org/tech_docs/005.html> for details.
+
+The information exchanged using ISUPPORT can be used to detect configuration
+incompatibilities (different maximum nick name length, for example) and
+therefore to disconnect the peer prior to registering it in the network.
+
+
+II.3 Exchange channel-modes, topics, and persistent channels

+ngIRCd supports one aspect of Zeroconf Networking[1]: Multicast DNS (mDNS[2])
+with DNS Service Discovery (DNS-SD[3]).
+
+To use this features you can use one of two APIs:
+
+  a) Apple "Bonjour" API as used by Mac OS X,
+  b) the Howl[4] Zeroconf library or the Howl compatibility layer
+     of the newer Avahi[5] library.
+
+When calling the configure script using the "--with-zeroconf" switch the
+avalable API will be autodetected and the required additional libraries will
+be linked to the ngircd binary as required.
+
+ngIRCd then registers a DNS-SD service for each port it is listening on using
+the service type "_ircu._tcp.".
