It's a few months late, but the first release candidate for
X Server 1.7 is now available. Peter Hutterer announced the release this morning along with freezing the X Server ABI for the 1.7 series. A
X Server 1.7 snapshot was made available earlier this month, but a few more bug-fixes can be found in today's release candidate.
Peter is planning at least a second release candidate before X Server 1.7.0 is released and then the release of
X.Org 7.5. Notably, X Server 1.7 brings support for
Multi-Pointer X.
The X Server 1.7 RC1 release announcement with download links can be found on
xorg-announce.
