We are pleased to announce this major release of the xf86-video-intel
2D driver. It contains many correctness and performance improvements
compared to the 2.11 releases. We encourage everyone using 2.11 to
upgrade to 2.12.
This release contains several bug fixes since the earlier 2.11.901
release candidate---see below for details.

Notable changes in 2.12.0 compared to 2.11
==========================================
New requirements compared to 2.11
---------------------------------
* Libdrm >= 2.4.21
Major performance improvements
------------------------------
There have been many performance improvements targeting the
915G/945G/Pineview graphics chipsets (thank to Chris Wilson!). Areas
improved include:
* Major improvements to glyph rendering
* Avoid software fallback when using extended desktops, (for example,
video playback)
* Better performance when using large windows, (for example with
firefox scrolling)
* Avoiding migration ping-pong with gigantic drawing
The following speedups (measured with cairo-perf-trace/cairo-traces)
capture some of the improvements. These were measured on a Pineview
system with X server 1.8.1. This compares how this 2.12 release
improves performance compared to 2.11.0:
Trace Speedup
----- -------
ocitysmap 5.41x speedup
firefox-talos-gfx 2.41x speedup
gnome-terminal-vim 2.15x speedup
poppler 1.86x speedup
firefox-planet-gnome 1.43x speedup
midori-zoomed 1.39x speedup
swfdec-giant-steps 1.36x speedup
xfce4-terminal-a1 1.17x speedup
evolution 1.09x speedup
swfdec-youtube 1.06x speedup
Other improvements
------------------
Daniel Vetter improved Xvmc and overlay, adding GEM support.
Bug fixes
---------
There have been many conformance improvements targeting the
915G/945G/Pineview graphics chipsets. The rendercheck test suite
passes once again and there has been a significant reduction in the
number of errors detected by the cairo test suite (notably center
sampling and EXTEND_NONE behaviors are fixed).
Other notable bug fixes include:
* Fix for bug 28446 Garbled fonts with Mathematica
https://bugs.freedesktop.org/show_bug.cgi?id=28446
* Fixes for page-flipping and other DRI2-handling bugs, (Thanks Jesse
Barnes, and Kristian Høgsberg)
* Avoid corruption when using extended desktops, (for example, video
playback)
(The bug fixes below are new since the 2.11.901 release candidate)
* Fix corrupted output when screen rotated
https://bugs.freedesktop.org/show_bug.cgi?id=28461
* Fix corrupted rendering in KDE due to missing flush.
* Fixes i830_uxa_put_image for the following issues:
Bug 28569 - [i965] IGN's flash-based video player crashes X
https://bugs.freedesktop.org/show_bug.cgi?id=28569
Bug 28573 - [i965] Fullscreen flash and windowed SDL games fail to
update the screen
https://bugs.freedesktop.org/show_bug.cgi?id=28573
* Fix visual corruption of scrollbar in Chromium
* Fix tiling limits to resolve this issue:
