Snapshot 2.99.917 (2014-12-21)
==============================
3 months drifted by whilst I looked elsewhere for bugs.. The highlight of
bugs fixed here are a couple of workarounds required for Broadwell and
making sure that the rasterisation code is symmetric under inversions.
However, as a couple of crashers slipped through into 2.99.916 (though
not actual regressions in 2.99.916 per se) and 3 months have passed, we
should make one more snapshot before an imminent release.

 * Beware of recomputing the clear hint in the middle of MI recursion
   https://bugs.freedesktop.org/show_bug.cgi?id=77074

 * Fix crash from rendering an empty Glyph string under PRIME as the
   secondary driver

 * Restore application of default monitor options to the first output,
   a regression in 2.99.915 and the MST support
   https://bugs.gentoo.org/show_bug.cgi?id=522500

 * Finally fix ZaphodHeads blocking on waiting for flip completion events.
   Before kernel 3.19, O_NONBLOCK support is broken and so we must avoid
   reading if we are not expecting an event.

 * Backwards compatibilty fix for fake triple buffering with PRIME and
   Xorg-1.15
   https://bugs.freedesktop.org/show_bug.cgi?id=85144#c12

 * Fix a rendering issue with output rotation and software fallbacks.
   https://bugs.freedesktop.org/show_bug.cgi?id=84653

 * Enable MST discovery even without udev support
   https://bugs.freedesktop.org/show_bug.cgi?id=84718

 * Fix TearFree operation after the GPU is wedged
   https://bugs.freedesktop.org/show_bug.cgi?id=85058

 * Fix projective sampling on gen6+.

 * Fix rendering and corruption with gen8.
   https://bugs.freedesktop.org/show_bug.cgi?id=84958
   https://bugs.freedesktop.org/show_bug.cgi?id=83207
   https://bugs.freedesktop.org/show_bug.cgi?id=79053
   https://bugs.freedesktop.org/show_bug.cgi?id=81583

 * Fix crash when using Xinerama.
   https://bugs.freedesktop.org/show_bug.cgi?id=87207

 * Fix rendering of right-to-left or bottom-to-top PolySegments in UXA

How imminent is imminent?  This driver hasn't had a proper release in
over a year and a half, this is getting ridiculous...

What happened to the "release early/release often" rule? It has pushed
OSS much faster forward than it now goes.

Distributions are forced to randomly pick some git snapshot. Often it's
not too much stuff broken. No stable release or branch we can rely on.

Is Intel not able to maintain its own device driver in a usable way?

I also wonder what's going on.

[Lampshade]

Bump for February
When is Intel going to release stable xorg driver?
Maybe they are going to develop driver only for 
internal purposes and this is the main cause of not
releasing stable driver for distributions and end users?
