Please do NOT use this VirtualBox Release Candidate release on production machines. A VirtualBox Release Candidate should be considered a bleeding-edge release meant for early evaluation and testing purposes.

You can download the binaries here.

Please do NOT open bug reports at http://www.virtualbox.org/wiki/Bugtracker but use our VirtualBox Beta Feedback forum to report any problems with the Beta. Please concentrate on reporting regressions since VirtualBox 4.3.28.
