We released Buildr 1.4.6 in June which added support for Scala 2.9.0+ and included 18 other minor fixes and improvements. I expect we'll release version 1.4.7 in the September/October timeframe.
Thanks to the work of Peter Donald and Antoine Toulme, our continuous integration tests are back working on Apache's Jenkins infrastructure.
Mailing list has been somewhat active – higher than previously in 2011 but below 2010 averages. We still have a few outstanding contributions sitting in Jira that need some cleanup and/or committer time to integrate them.
We have no issues that require board attention.
