Available immediately is BuddyPress 1.5.6. This maintenance release addresses WordPress 3.4 compatibility, and fixes five other annoyances. If you are using anything from the BuddyPress 1.5 family, this is a 100% safe update to make.
We’re also putting out a beta of BuddyPress 1.6 later this week. The new forums integration is a bit raw, so we’re pushing that out until 1.7 to get all the new BuddyPress hotness out sooner. Stay tuned!
