Development versions (beta or RC) are not recommended for live SMF forums, as they are still being tested. Interested admins may install development versions, in order to familiarize themselves with new features and options for users and administrators, and for testing. They are available at download.simplemachines.org. Many of your favorite mods may not be compatible with the development versions of the forum.
