The latest CVS snapshot is now available from:
http://www.devolution.com/~slouken/SDL/download.html
It fixes some CD detection problems and 8-bit audio mixing under Linux.
This is also the first CVS snapshot in a while that should be completely
stable under Win32. As of now, SDL should be completely stable on all
supported platforms. Please bang on it as hard as you can, and report
any bugs! 
Thanks,
