We are pleased to announce that Mylyn 3.0.5 is now available and supports Eclipse 3.4 and 3.3: http://eclipse.org/mylyn/downloads/
The reason for this update is support for Bugzilla 3.2.2 which was recently released. A list of resolved bugs is linked from New & Noteworthy: http://eclipse.org/mylyn/new/
Mylyn 3.0.5 will also be included in the upcoming Eclipse Ganymede SR2 release which is expected at the end of February. The maintenance release will be followed by Mylyn 3.1 in March.
