I meant to blog about this earlier but have been busy lately, so I'm going to cheat and copy from the post I sent to the OpenSolaris X Window System community mailing list last week.
Xorg 6.9 & 7.0 Release Candidate 1 has been released by the X.Org Foundation. The announcement and pointers to sources can be found at:
http://lists.freedesktop.org/archives/xorg/2005-October/010668.html
Highlights of changes in this release are found at:

Detailed change logs for those who want gory levels of detail can be found at:

Particularly interesting things to test on Solaris include:
Option "BellDevice" "/dev/audio"
Also, while I've been regularly building both the 6.9/imake-based and 7.0/autoconf-based trees on Solaris 10 on SPARC and x86, those who want to run on older OS releases may want to check to make sure everything still builds and runs well on them.
I've integrated it with our Solaris Xorg sources, and made test packages available inside Sun, but unfortunately can't release on opensolaris.org right now - if all goes well, they should be integrated into an upcoming Nevada build and distributed via Solaris Express.
These will also form the basis of our initial X source release via OpenSolaris, which is still planned for later this quarter.
