"Some time ago, Cyril asked me if there might be a snapshot for 2.15. The good news is that today is that day! And here it is," announced Chris.
Unfortunately, xf86-video-intel 2.15 isn't particularly exciting. Found in the 2.15 code-base is mostly a bunch of bug-fixes, but no new hardware support (Sandy Bridge already landed in xf86-video-intel 2.15.0 and it's too early for Ivy Bridge yet), no performance enhancements, and no other new features are introduced in the user-space X.Org driver side.
Some of the bug-fixes in xf86-video-intel 2.15.0 are addressing green pixels when displaying partially off-screen videos, deferred creation of glyph cache to generation start-up, incorrect maximum addresses for video decoder states, failure to handle over-sized temporary surfaces, relaxing tiling corruption on older Intel "Gen2" hardware, and a crash when destroying a foreign DRI drawable.
Plus other changes mentioned in the announcement along with the source download links for this 2.15 snapshot that is marked as xf86-video-intel 2.14.901. Per the usual trend as of late, Chris Wilson's work dominates the Intel driver's change-log. Look for the official xf86-video-intel 2.15 and Intel 2011Q1 packages to be released in a couple of weeks.
