Just upgraded here; everything at this point is stock code only (will likely add the BBCode tags I like into this site vs what will be stock; the extended ones will be at UBBDev once Public Beta hits the streets).
Loads of new features; check UBBCentral for the changelog.
At this point I don't have a Sandbox account setup at PayPal, but will contemplate signing up for one in the meantime to allow everyone a chance to play...
