We’re not quite done yet, so please test this beta as much as possible. Bugs should be reported on the BuddyPress Trac server, but you can also discuss potential issues with other users on the BuddyPress forums.
We’re three days later than expected with this beta. WordPress MU 2.7 was released yesterday, it made much more sense to sync up the release schedules to ensure there were no compatibility problems. The 1.0 release will now be February 12th, exactly two weeks from today.
I’m glad to see that BuddyPress and WordPress MU appear to be synchronizing their releases with the WordPress.org project. Keeping everything on the same page and release schedule I think will make things easier for end users of the software.
