+  ngIRCd 19.2~rc1 (2012-06-13)
+  - New configuration option "CloakHostModeX" to configure the hostname
+    that gets used for IRC clients which have user mode "+x" enabled.
+    Up to now, the name of the IRC server itself has been used for this,
+    which still is the default when "CloakHostModeX" isn't set.
+  - Correctly handle asynchronously re-established server links: a race
+    condition could let the daemon loose track of an already re-established
+    incoming server link while preparing its own outgoing connection.
+    Peers that both try to connect each other could have been affected.
+  - Log a debug message when SIGUSR2 is handled in debug mode.
+  - Only allow alphanumeric characters in user-supplied user names of
+    USER command and IDENT replies.
+  - Change wording of "TLS initialized" message to make it more consistent.
+  - Don't leak file descriptors on error path when creating "PID files".
+  - Add missing mode "r" to CHANMODES in 005 "ISUPPORT" numeric.
+  - Update doc/Modes.txt and doc/Platforms.txt documents.
+  - contrib/platformtest.sh: correctly detect Open64 C compiler and handle
+    "CC=xxx MAKE=yyy ./platformtest.sh" calling convention.
+  - Add instructions for setting up Atheme IRC services.
+  - Implement support for IRC capability handling, the new "CAP" command,
+    and capablity "multi-prefix" which allows both the NAME and	WHO command
+    handlers to return more than one "class prefix" to the client.
+  - Update Xcode project files: reference missing documentation files.
+  - Fix: Don't ignore "permission denied" errors when enabling chroot.
+  - FAQ: enhance description of chroot setup.

+This document lists and describes the "IRC capabilities" that ngIRCd supports
+and can be requested by a IRC/IRCv3 client that supports the "CAP" command.
+
+ngIRCd implements the "IRC Client Capabilities Extension" as described here:
+<http://www.leeh.co.uk/draft-mitchell-irc-capabilities-02.html>
+
+
+I. Supported Capabilities
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+None. At the moment, ngIRCd supports the "CAP" command and its sub-commands
+but offers no capabilities that could be requested by a client.

doc/FAQ.txt

@@ -64,11 +64,19 @@ A: ngIRCd does not write its own log file. Instead, ngIRCd uses syslog(3).
 
 Q: I cannot connect to remote peers when I use the chroot option, the
    following is logged: "Can't resolve example.com: unknown error!".
+A: see next question blow ...
+
+Q: When running ngIRCd inside a chroot, no IP addresses can be translated
+   in DNS names, errors like "Name or service not known" are logged.
 A: On Linux/glibc with chroot enabled you need to put some libraries inside
    the chroot as well, notably libnss_dns; maybe others. Unfortunately, even
-   linking ngIRCd statically does not help this. The only known workaround
-   is to either disable chroot support or to link against dietlibc instead
-   of glibc. (tnx to Sebastian Siewior)
+   linking ngIRCd statically does not help this. So you can either copy
+   all the required files into the chroot directory:
+     $ mkdir -p ./chroot/etc ./chroot/lib
+     $ cp -a /etc/hosts /etc/resolv.conf /etc/nsswitch.conf ./chroot/etc/
+     $ cp -a /lib/libresolv* /lib/libnss_* ./chroot/lib/
+   Or you can try to link ngIRCd against an other C library (like dietlibc)
+   that doesn't depend on NSS modules and/or these files.
 
 Q: I have added an [Oper] section, how do i log on as IRC operator?
 A: You can use the /OPER command in your IRC client to become an IRC operator.
