There has been nothing "exciting or new" about UBB other then UBB itself as of late. I beleive the developers here are doing what they can to keep their modifications up to date with the pace of which new releases of UBB are coming out and supporting each version there of.
Until UBB can actualy handle plugins as discussed the other week in chit chat I think this project will never fully mature as who is going to want to re-code it for each new rendition of UBB that gets released.
