BackTrack 5 "revolution" Rolls Out
BackTrack, an Ubuntu-based penetration-testing distribution, offers "major improvements" over previous releases, including support for 32- and 64-bit architectures, KDE 4, Gnome, and Fluxbox.
Based on Ubuntu Lucid LTS and kernel 2.6.38, the new BackTrack is fully open source and GPL-compliant.
"Perhaps most importantly BackTrack 5 'revolution' will be our first release to include full source code in its repositories," says a March update on the BackTrack blog. "This is a big thing for us, as it officially joins us to the open-source community and clears up any licensing issues which were present in BackTrack 4."
