This is to announce the release of Icecast 2.3.2

2.3.2 is mainly a bug fix release with a couple of new items that may be 
of interest to a few of you. Even if the new features are not of 
interest, it is still highly recommended that you update to 2.3.2.

A summary of the changes is included below

- Character set support.

Most non-Ogg streams (eg MP3) send metadata as Latin1 but it could be in 
other character sets.  As icecast uses UTF-8, we need to convert to 
UTF-8 so that web pages and stream directories render correctly.

   . Allow a per-mount <charset> setting.  For when source clients do not
     indicate which character set is in use.
   . a charset= parameter to the metadata request.
   . Default for non-Ogg content is now Latin-1 (aka ISO-8859-1),  Ogg
     content still uses UTF-8.

- Authentication

   . Each mountpoint authentication is isolated so one mount
     authentication does not slow another mountpoint authentication down.
   . XSL pages can require authentication.
   . Add some sanity checks for incorrect settings.

- Listening socket update

   . Allow multiple ports to be allocated which allow multiple shoutcast
     source clients to stream on the same icecast instance.
   . No internal limit on the number of listen-sockets that can be used.
   . Allow for a listen-socket to be marked SSL capable. While any client
     could connect on these, the idea is really for /admin requests.
   . allow for a <listen-socket> to bind to ipv4 and ipv6

- XSL update

   . XSL pages include an xspf link for non-auth streams.
   . XSL pages in both webroot and adminroot can take a mount= arg to
     limit which stats are transformed.
   . XSL files can specify the content-type to return to the client. It
     is no longer fixed to html

- Updates for stream directory handling.

   . A stream is not registered with the directory until after the first
     minute has passed. A few streams get stuck in a connect/disconnect
   . Increase retry time on failure, if the stream add is rejected then
     it will be down to a misconfiguration so a long retry delay is
   . A YP server that is not responding is ignored for a while

- Updates for Win32

   . Build cleanups,
   . Newer versions of dependency libs (libxml2/libxslt/libcurl etc)
   . buffer overflow fixes when many streams are active

- Accept/Ban IP support.

Now takes filenames for explicitly accepting or denying requests from 
specified IP addresses.  Useful in cases where firewall access is not 
available.  The files, if defined, are re-read automatically if updated.

- A Mountpoint is exported to the slaves even if no mount section is 
defined for it. You can still use the hidden setting to prevent that 
from happening.

- Relays handle redirection (HTTP 302) if one is received at startup.

- Automatically generate XSPF playlist like we do with M3U, mountpoint 
extension is .xspf

- Header updates for proxy handling and certain clients like some 
shoutcast source clients and flash players.

- Added Kate/Skeleton codecs to Ogg handler.

- Various stats cleanups. Added some global stats (server ID, email 
contact etc).

- The streamlist passed from master to slave had a limited length, so if 
there were many streams then some could of been left out.

- Documentation updates.

- Relay startup/shutdown is cleaner.

- several build cleanups.

- several resource leaks and race conditions fixed

Known issues

If you have customized xsl pages then you may need to add a media-type 
and/or method at the top of the xsl page.

If you are on a BSD platform with IPv6 support, you may need to use a 
bind-address tag. There are some concerns on these platforms for 
supporting a combined IPv4/IPv6 socket.

If using a win32 service setup. Some systems may require a reboot 
between a remove and a reinstall. This is because the delete service 
routine only marks the service for deletion and can prevent a re-install 
from completing.
