BackTrack 5 will be based on, and will (finally) support both 32 bit and 64 bit architectures. We will be officially supporting, Gnome and Fluxbox while providing users streamlined ISO downloads of each Desktop Environment (DE) Tool integration from our repositories will be seamless with all our supported DE’s, including the specific DE menu structure. Backtrack 5 “revolution” will be our first release to include full source code in it’s repositories. The codename of this release will be “”, for a bunch of reasons.
