X11R7.6 development is currently underway.
Features Added/Enhanced
XCB included in the katamari, required by libX11 1.4 and some clients.
Xorg server 1.8 changes, including new input hotplugging and configuration framework
Documentation: Most protocol & API docs moved from xorg-docs into individual proto/library modules, converted from legacy formats to DocBook/XML where possible.
Massive amounts of configure.ac/Makefile.am cleanup & improvement. Lots of previously duplicated bits moved to xorg-macros (requiring recent xorg-macros versions when we build the tarballs, but unless you autoreconf that shouldn't affect people building from tarballs).
Most of the COPYING file stubs have been replaced with actual copies of the copyright & license notices for easier packaging by distributors who provide such notices in their packages.
Features Removed
TODO
At this point in the release cycle, these will probably not make this release
New Input Hotness: Xi 3 & XKB 2 (DanielStone, PeterHutterer)
- Disable XFree86-DGA requests except relative mouse motion, until Xinput 2 allows killing it all.
Referee DoubleBuffer vs. MultiBuffer vs. libfb/Composite
Add Solaris Trusted Extensions security module which uses XACE (AlanCoopersmith).
- Multiple PCI cards doesn't work particularly well anymore.
Shatter (cf description in git), in some form or other (AdamJackson, CorbinSimpson)
Schedule
Sometime around September/October 2010, more exact dates to be decided. See if ReleaseSchedule is updated.
