I released the first version (0.1) of Patchwork a few days ago. Patchwork is the new (open source!) version of the patch tracking system originally written for the Linux PPC64 mailing list - it 'catches' patches that have been posted to a mailing list, and lists them on a web page for the project's maintainer to track.

Since then, I've released version 0.2, which has MySQL support (in addition to PostgreSQL) as well as a few parser and documentation improvements.

Check out the setup for linuxppc64-dev over here. Also new: freshmeat.net project page.
