I have noticed that UBB.threads 8.0 will go to the beta testers in two phases, first for the admin panel and then for the user interface.

I'm guessing afterward will be the public beta stage. Do you know how will this work? Since this is a huge release, I personally think there should be a Gamma (aka Release Candidate) version just after the public beta stage but before UBB.threads 8.0 goes Gold. That way we can ensure there are no lingering bugs before the Gold release.
