The X.org project is working towards the next major release, with August seeing mostly minor releases of various X components. Most notably of these were the mesa 9.2 release, new -intel and -ati driver releases, and a second pre-release of a new stable Xserver.
The Xserver release candidate 1.14.2.902 includes half a dozen small bug fixes on top of the earlier .901 release, in preparation for the 1.14.3 stable release.
The two -intel driver releases includes some Haswell performance tuning, RGB overlay support for Ironlake and later, and various other fixes. Most changes were to the SNA code path.
The -ati release is significant, as this is the first release in some time. This adds PCI IDs and support for a huge range of newer ATI hardware (Sea Islands, Southern Islands, Richland, and Kabini APU), reverse prime support, 2d tiling support and glamor 2d acceleration for radeonsi, and various fixes and enhancements.
