WARNINGS (for the release notes)

  • The -d switch won't behave the same as in 0.8.3. This is a temporary thing, we'll likely bring it back to its original behaviour for next releases. If you're curious, -d will now change heart beating rate.
  • Support for MIT SHM X extention is disabled by default `cause it broke (*grin*). We'll get it back on next release. Let us know if you really notice a performance degradation on the rendering side please.


  • Design a sensible media handler interface
  • Implement ffmpeg and gstreamer backends stably.
  • Fix all matrix regressions and preferably get it working properly.
  • Add XPI packaging support for Firefox.
  • Fix all blocker bugs: open blocker/security bugs.
