-ngIRCd 0.10.3 (2007-07-31)
+ngIRCd 0.12.1 (2008-07-09)
+
+  - Allow mixed line terminations (CR+LF/CR/LF) in non-RFC-compliant mode
+  - Don't allow stray \r or \n in command parameters
+  - --configtest: return non-zero exit code if there are errors
+  - Update ngIRCd manual pages
+  - Add option aliases -V (for --version) and -h (for --help).
+  - Fix 'no-ipv6' compile error.
+  - Make Listen parameter a comma-seperated list of addresses. This also
+    obsoletes ListenIPv4 and ListenIPv6 options. If Listen is unset, it
+    is treated as Listen="::,0.0.0.0".
+    Note: ListenIPv4 and ListenIPv6 options are still recognized,
+    but ngircd will print a warning if they are used in the config file.
+
+ngIRCd 0.12.0 (2008-05-13)
+
+  - Fix Bug: 85: "WHO #SecretChannel" that user is not a member of now returns
+    proper RPL_ENDOFWHO_MSG instead of nothing. (Ali Shemiran)
+  - Fix complie on FreeBSD 5.4 and AIX.
+  - If bind() fails, also print ip address and not just the port number.
+
+  ngIRCd 0.12.0-pre2 (2008-04-29)
+  - IPv6: Add config options to disabe ipv4/ipv6 support.
+  - Don't include doc/CVS.txt in distribution archive, use doc/GIT.txt now!
+  - Documentation: get rid of some more references to CVS, switch to GIT.
+  - Get rid of cvs-version.* and CVSDATE definition.
+  - Report ERR_NOTONCHANNEL when trying to part a channel one is not member of.
+  - Testsuite: remove erroneous ConfUID setting in config file.
+
+  ngIRCd 0.12.0-pre1 (2008-04-20)
+  - Include Mac OS X Xcode project in distribution archives.
+  - Do not exit on SIGHUP or /REHASH if the config file cannot opened.
+  - Add IPv6 support.
+  - Install a LaunchDaemon script to start/stop ngIRCd on Mac OS X.
+  - Implemented IRC commands INFO, SUMMON (dummy), and USERS (dummy) and
+    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)
+  - Implement RFC 2812 handling of "0" argument to 'JOIN': must be treated
+    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)
+
+  - Fix sending of JOIN commands between servers when remote server appended
+    mode flags. (Rolf Eike Beer) [from HEAD]
+  - Send "G" instead of "H" flag in WHO replies. (reported by Dana Dahlstrom)
+  - Under some circumstances ngIRCd issued channel MODE message with a
+    trailing space. (Dana Dahlstrom) [from HEAD]
+
+ngIRCd 0.11.0 (2008-01-15)
+
+  ngIRCd 0.11.0-pre2 (2008-01-07)

+    ngircd to crash [from HEAD].
+  
+  ngIRCd 0.11.0-pre1 (2008-01-02)
+  - Use dotted-decimal IP address if hostname is >= 64.
+  - Add support for /STAT u (server uptime) command.
+  - New [Server] configuration Option "Bind" allows to specify
+    the source ip adress to use when connecting to remote server.
+  - New configuration option "MaxNickLength" to specify the allowed maximum
+    length of user nick names. Note: must be unique in an IRC network!
+  - Enhanced the IRC+ protocol to support an enhanced "server handshake" and
+    enable server to recognice numeric 005 (ISUPPORT) and 376 (ENDOFMOTD).
+    See doc/Protocol.txt for details.
+  - Re-added doc/SSL.txt to distribution -- got lost somewhere!?
+  - Fixes the wrong logging output when nested servers are introduced
+    to the network as well as the wrong output of the LINKS command.
+  - Update Mac OS X Xcode project file for Xcode 3.
+  - Adjust test suite to be usable on HP/UX 11.11 :-)
+  - Fix code to compile using K&R C compiler and ansi2kr again.
+  - New config option NoDNS: Disables DNS lookups when clients connect.
+  - Fixed propagation of channel mode 'P' on server links.
+  - Numeric 317: implemented "signon time" (displayed in WHOIS result).
+  - Fixed code that prevented GCC 2.95 to compile ngIRCd.
+  - Adjust path names in manual pages according to "./configure" settings.
+  - Added new server configuration option "Passive" for "Server" blocks to
+    disable automatic outgoing connections (similar to -p option to ngircd,
+    but only for the specified server). (Tassilo Schweyer)
+  - 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.

-The source code of ngIRCd is maintained using the "Concurrent Versions
-System" (CVS). Thereby several developers can work with the source tree at
-the same time.
-
-
-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@ngircd.barton.de:/srv/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@ngircd.barton.de:/srv/cvs/ngircd checkout ngircd
-
-Thereby a new folder "ngircd" will be created containing all the individual
-source files. (Substitute the last "ngircd" with "website" to check out all
-the files of the homepage of ngIRCd.)
-
-The newly created folder ("ngircd" or "website") 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.
-
-
-II. 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>.

-Q: I am running Linux and ngircd dies on startup with the follwing errors:
-   IO subsystem: epoll (hint size 100, initial maxfd 100, masterfd -1).
-   Cannot initialize IO routines: Function not implemented
-   Server isn't listening on a single port!
-   ngircd exiting due to fatal errors!
-A: epoll is only supported on 2.6 Linux kernels. Either use a 2.6 kernel, or
-   re-run configure with the --without-epoll parameter. After configure
-   completed, you should see select() being listed as IO backend:
-   '(I/O backend: "select()"').

-II.2 Exchange channel-modes, topics, and persistent channels
+II.2 Enhanced Server Handshake
+
+The "enhanced server handshake" is used when both servers support this IRC+
+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

+                    alex@barton.de, http://www.barton.de/
+
+               ngIRCd is free software and published under the
+                   terms of the GNU General Public License.
+

+
+
+ngIRCd actually doesn't support secure connections for client-server or
+server-server links using SSL, the Secure Socket Layer, by itself. But you can
+use the stunnel(8) command to make this work.
+
+  <http://stunnel.mirt.net/>
+  <http://www.stunnel.org/>
+
+Stefan Sperling (stefan at binarchy dot net) mailed me the following text as a
+short "how-to", thanks Stefan!
+
+
+=== snip ===
+    ! This guide applies to stunnel 4.x !
+
+    Put this in your stunnel.conf:
+
+        [ircs]
+        accept = 6667
+        connect = 6668
+
+    This makes stunnel listen for incoming connections
+    on port 6667 and forward decrypted data to port 6668.
+    We call the connection 'ircs'. Stunnel will use this
+    name when logging connection attempts via syslog.
+    You can also use the name in /etc/hosts.{allow,deny}
+    if you run tcp-wrappers.
+
+    To make sure ngircd is listening on the port where
+    the decrypted data arrives, set
+
+        Ports = 6668
+
+    in your ngircd.conf.
+
+    Start stunnel and restart ngircd.
+
+    That's it.
+    Don't forget to activate ssl support in your irc client ;)
+=== snip ===
+
+
+Probably ngIRCd will include support for SSL in the future ...

+.TH ANSI2KNR 1 "19 Jan 1996"
+.SH NAME
+ansi2knr \- convert ANSI C to Kernighan & Ritchie C
+.SH SYNOPSIS
+.I ansi2knr
+[--varargs] input_file [output_file]
+.SH DESCRIPTION
+If no output_file is supplied, output goes to stdout.
+.br
+There are no error messages.
+.sp
+.I ansi2knr
+recognizes function definitions by seeing a non-keyword identifier at the left
+margin, followed by a left parenthesis, with a right parenthesis as the last
+character on the line, and with a left brace as the first token on the
+following line (ignoring possible intervening comments).  It will recognize a
+multi-line header provided that no intervening line ends with a left or right
+brace or a semicolon.  These algorithms ignore whitespace and comments, except
+that the function name must be the first thing on the line.
+.sp
+The following constructs will confuse it:
+.br
+     - Any other construct that starts at the left margin and follows the
+above syntax (such as a macro or function call).
+.br
+     - Some macros that tinker with the syntax of the function header.
+.sp
+The --varargs switch is obsolete, and is recognized only for
+backwards compatibility.  The present version of
+.I ansi2knr
+will always attempt to convert a ... argument to va_alist and va_dcl.
+.SH AUTHOR
+L. Peter Deutsch <ghost@aladdin.com> wrote the original ansi2knr and
+continues to maintain the current version; most of the code in the current
+version is his work.  ansi2knr also includes contributions by Francois
+Pinard <pinard@iro.umontreal.ca> and Jim Avera <jima@netcom.com>.

+ * Usage:
+	ansi2knr [--filename FILENAME] [INPUT_FILE [OUTPUT_FILE]]
+ * --filename provides the file name for the #line directive in the output,
+ * overriding input_file (if present).
+ * If no input_file is supplied, input is read from stdin.
+ * If no output_file is supplied, output goes to stdout.
+ * There are no error messages.
+ *
+ * ansi2knr recognizes function definitions by seeing a non-keyword
+ * identifier at the left margin, followed by a left parenthesis, with a
+ * right parenthesis as the last character on the line, and with a left
+ * brace as the first token on the following line (ignoring possible
+ * intervening comments and/or preprocessor directives), except that a line
+ * consisting of only
+ *	identifier1(identifier2)
+ * will not be considered a function definition unless identifier2 is
+ * the word "void", and a line consisting of
+ *	identifier1(identifier2, <<arbitrary>>)
+ * will not be considered a function definition.
+ * ansi2knr will recognize a multi-line header provided that no intervening
+ * line ends with a left or right brace or a semicolon.  These algorithms
+ * ignore whitespace, comments, and preprocessor directives, except that
+ * the function name must be the first thing on the line.  The following
+ * constructs will confuse it:

+ * The original and principal author of ansi2knr is L. Peter Deutsch
+ * <ghost@aladdin.com>.  Other authors are noted in the change history
+ * that follows (in reverse chronological order):
+
+	lpd 2000-04-12 backs out Eggert's changes because of bugs:
+	- concatlits didn't declare the type of its bufend argument;
+	- concatlits didn't recognize when it was inside a comment;
+	- scanstring could scan backward past the beginning of the string; when
+	- the check for \ + newline in scanstring was unnecessary.
+
+	2000-03-05  Paul Eggert  <eggert@twinsun.com>
+
+	Add support for concatenated string literals.
+	* ansi2knr.c (concatlits): New decl.
+	(main): Invoke concatlits to concatenate string literals.
+	(scanstring): Handle backslash-newline correctly.  Work with
+	character constants.  Fix bug when scanning backwards through
+	backslash-quote.  Check for unterminated strings.
+	(convert1): Parse character constants, too.
+	(appendline, concatlits): New functions.
+	* ansi2knr.1: Document this.
+
+	lpd 1999-08-17 added code to allow preprocessor directives
+		wherever comments are allowed
+	lpd 1999-04-12 added minor fixes from Pavel Roskin
+		<pavel_roskin@geocities.com> for clean compilation with
+		gcc -W -Wall
+	lpd 1999-03-22 added hack to recognize lines consisting of
+		identifier1(identifier2, xxx) as *not* being procedures
+	lpd 1999-02-03 made indentation of preprocessor commands consistent
+	lpd 1999-01-28 fixed two bugs: a '/' in an argument list caused an
+		endless loop; quoted strings within an argument list
+		confused the parser
+	lpd 1999-01-24 added a check for write errors on the output,
+		suggested by Jim Meyering <meyering@ascend.com>
+	lpd 1998-11-09 added further hack to recognize identifier(void)
+		as being a procedure
+	lpd 1998-10-23 added hack to recognize lines consisting of
+		identifier1(identifier2) as *not* being procedures
+	lpd 1997-12-08 made input_file optional; only closes input and/or
+		output file if not stdin or stdout respectively; prints
+		usage message on stderr rather than stdout; adds
+		--filename switch (changes suggested by
+		<ceder@lysator.liu.se>)
+	lpd 1996-01-21 added code to cope with not HAVE_CONFIG_H and with
+		compilers that don't understand void, as suggested by
+		Tom Lane
+	lpd 1996-01-15 changed to require that the first non-comment token
+		on the line following a function header be a left brace,
+		to reduce sensitivity to macros, as suggested by Tom Lane
+		<tgl@sss.pgh.pa.us>
+	lpd 1995-06-22 removed #ifndefs whose sole purpose was to define
+		undefined preprocessor symbols as 0; changed all #ifdefs
+		for configuration symbols to #ifs
+	lpd 1995-04-05 changed copyright notice to make it clear that
+		including ansi2knr in a program does not bring the entire
+		program under the GPL
+	lpd 1994-12-18 added conditionals for systems where ctype macros
+		don't handle 8-bit characters properly, suggested by
+		Francois Pinard <pinard@iro.umontreal.ca>;
+		removed --varargs switch (this is now the default)
+	lpd 1994-10-10 removed CONFIG_BROKETS conditional
+	lpd 1994-07-16 added some conditionals to help GNU `configure',
+		suggested by Francois Pinard <pinard@iro.umontreal.ca>;
+		properly erase prototype args in function parameters,
+		contributed by Jim Avera <jima@netcom.com>;
+		correct error in writeblanks (it shouldn't erase EOLs)
