The xorg-server 1.9.3 release though isn't particularly exciting, so even if you are in one of the snow-filled parts of the world right now with nothing better to do, it's not necessarily worth expediting your build process or package update to the 1.9.3 release. At least though it will continue to work with the just-released Catalyst Linux 10.12 driver.
Officially there are 52 fixes found in this third maintenance release. These bug fixes concern performance, stability, and correctness, but none of them are too dramatic. There's even a couple KDrive fixes. Most of the fixes though are just for Apple's XQuartz.
The release announcement for X.Org Server 1.9.3 can be found on the X mailing list. X.Org 7.6 still hasn't been released (it was supposed to come in October, but the release candidate didn't arrive until November), so unless X.Org Server 1.10 (or X.Org Server 1.9.4) makes it out before hand, this next X.Org katamari release should ship the 1.9.3 package.
For those interested in something a bit more exciting as you drink your winter Glühwein, Gløgg, or Jägertee, there is the first X.Org Server 1.10 development snapshot that arrived last week. Due to some last minute additions, the 1.10 release due out in February will bring RandR 1.4 with per-CRTC pixmap support and spirte transforms, X Fence Sync support, and a whole lot of bug-fixes. Fortunately it's without merging the drivers back into the X Server.
