I downloaded ubbthreads-5-5-1.tar.gz from the Members Area and I just did a fresh install of ubbthreads-5-5-1.tar.gz, with fresh files and tables. After completing the installation and creating the admin user I see at the bottom that the installed version is "UBB.threadsâ„¢ 5.5-beta2". Is there any non-beta software available?
