Re: testbp.org
testbp.org always runs the bleeding edge version of BuddyPress. This means the current trunk version ( give a few minutes or hours since Andy needs to updated it when he commits a new changeset to trunk).
So, at this very moment, testbp.org is running the recently released 1.1. In fact, it was running this version before it was publicly released. Wait a day or so, and it will be running an even newer trunk version.
