Back Track 4 Linux
BackTrack 4 is out and along with this release come some exciting news, updates, and developments. BackTrack 4 has been a long and steady road, with the release of a beta last year. Authors decided to hold off on releasing BackTrack 4 final until it was perfected in every way, shape and form. This release includes a new kernel, a larger and expanded toolset repository, custom tools that you can only find on BackTrack, and more importantly, fixes to all (well, most) major bugs that are known.

The BackTrack Team is proud to announce the public release of BackTrack 4 R1. At the risk of sounding like a broken record, we believe this version is by far the best version released to date. With a shiny new 2.6.34 kernel, there are many significant improvements, such as expanded hardware support, and improved desktop responsiveness.
