SMF 1.1 has been released to charter members! It will be released in the following days to regular members as well. If you want to get it a couple days early get a charter membership heh. A ton of fixes since 1.1 RC3 have been added and should be pretty easy to upgrade from 1.1 RC3. Finally SMF 1.1 is out and ready to use! Check out SMF at http://www.simplemachines.org
