The munin project trac got a bit of attention.
- Moved from a shared project server to a dedicated server
- Upgraded from 0.10.3 to 1.0
- Database migrated from sqlite to PostgreSQL
- Connected to the new git repositories instead of the old subversion repository.
The earlier conversion from SVN to Git has speeded up contributions quite a bit.
I'm very happy with the rate of pull requests on the contrib repository, which was moved first.
The munin repository has also proven to be a valuable intetgration point for contributions from distribution package maintainers and users.
