Maybe they hit some roadblock.
UBB 8 Has been installed on this site and UBBDEV for months but it still is not officially released yet.
Ruben, something must have happened or not happened.. We just don't know which,
I am curious as you. I need to migrate my site to something more modern because its obsolete but then PHP.8 is a must apparently.
Hopefully the UBB software owner lets us know sooner than later.
