After a testing period for over one month we made the decision to move X.org 7.3 to our stable package repositories. Thanks to all the testers and reporters who enabled us to wipe out most of the major issues.
Please note that libgl-dri has been renamed to libgl since the deprecation of libgl-mesa happened a long time ago already. That means people packaging for the AUR should finally get rid of any hard dependencies on libgl-dri or else their packages will be left broken.
