Some nice Direct3D proposals for Wine.
I think Python continues to be one of the most popular projects, with 30 accepted proposals. Several proposals filed under other projects are in fact Python-related as well.
Mozilla gets some nice proposals as well: TraceMonkey register allocation, web-rsync, ECMAScript 3.1 in Rhino, and dupe detection in Bugzilla.
Mercurial gets inotify for OS X and a client for git repositories.
