X.Org Server 1.18 Officially Released
While Keith Packard continued as usual in managing the X.Org Server tree for 1.18, it's Adam Jackson at Red Hat who finished it out and got this release to happen. This is part of some X.Org development/release process changes decided during this year's X.Org Developers' Conference in Toronto.
X.Org Server 1.18 has GLAMOR improvements, RandR 1.5 functionality, more PRIME functionality, mode-setting driver enhancements, and more.
X.Org Server 1.18 does bump the video ABI so that means the proprietary graphics drivers will need to see new releases... If you're using the NVIDIA Linux driver you're in good shape while AMD Catalyst users will need to wait for a new release, which could be a while considering the upstream driver still doesn't support the latest Linux 4.x kernel releases without third-party patches.
Adam Jackson announced the 1.18 release a short time ago on the X.Org mailing list. X.Org Server 1.19 is now under development in Git with the Ouzo codename.
