There are a few known bugs in 1.3.7.  The ones we've found are:

* icecast will not register on yp.shoutcast.com

* Readline sometimes fux up the terminal when icecast exits.
  If this continues to irritate you, press enter just before icecast exits.
  You can fix your terminal with the reset program 

* When using a streamer that changes bitrate on the stream, the source 
  sleeping will still sleep with old bitrate as indicator. Lower sleep_ratio to temporarily fix this.  

* Sometimes the client count is not correct.

If, or perhaps when, you find other bugs, please visit http://bugs.icecast.org

though you can also mail bugs to devel@icecast.org
