37 commits have landed in the Mesa 10.1 branch since the RC2 release last week and there's four more patches on the mailing list for review that are tagged for inclusion into Mesa 10.1 stable. Due to these last minute changes, Ian is looking at releasing Mesa 10.1 Release Candidate 3 on Friday, the originally planned release date for Mesa 10.1.
As a result of the RC3, Mesa 10.1 is now officially planned for release next week Tuesday, 4 March.
Mesa 10.1 is bringing with it many new features and just earlier today I did some 13-way R600/RadeonSI OpenGL benchmaks of the new Mesa 3D stack that will be found in Ubuntu 14.04 LTS. More Mesa 10.1 benchmarks are on the way on Phoronix in the days ahead.
Confirmation of the change of Mesa 10.1 release plans was made today to the Mesa-dev list.
