From the ChangeLog:
Doube click on icons launch Jubler (in Mac OSX, Windows and Debian systems). MPlayer fixes. Jubler installs in systems with JRE 1.6. MPlayer supports different audio stream. Video playback doesn't change system mixers. FFMPEG time offset and WMV bug fixes. Better handling of audio caches. Updated to newer version of FFMPEG. ASpell updates supported languages when opening preferences. Major internal changes and cleanups. Initial Debian package.

If you are a debian (unstable) user, please give me feedback if it works for you!

... so that it will be more human - friendly!

I have to move to the new site, since the old had tons of problems and day after day I had to take care of things, like fixing SQL tables, taking care of permissions etc.
Hopefully the new site will not suffer from these issues!
