Short bio: Computer Scientist, FOSS supporter (read more)
Tux Machines (TM)-specific
Due to a set of remotely exploitable bugs in Gaim and Mozilla-Firefox and locally exploitable bugs in QT and Kdelibs found in the last few hours before a final 2005.0 release was completed, it was decided by all of the members of Release Engineering to rebuild the release media to resolve these bugs, prior to release.
Release Engineering would like to thank the security team for their diligence in making sure Gentoo has top-notch security resolution, and also our Architecture Leads, for having the patience to put up with all of the last-minute updates and changes, and also for their assistance in quickly verifying these packages on their architectures.
