This is a bugfix release on the 0.9 branch of VLC. Notables bugfixes are :

- fullscreen behaviour on Windows with multiple screens,
- workaround bug with libxml2 >=2.7.3,
- video performance on Intel-based Macs,
- various decoders updates on Windows.

An experimental native decoder for Real Video 3.0 & 4.0 using FFmpeg has been added and many fixes happened in our Real Media demuxer.
This should improve Real Media Files support on all platforms.
