I sent this out over the weekend and never saw it arrive, so presuming
the announcement was lost in transit...
Release 2.19.0 (2012-04-29)
==========================More stability fixes for UXA and support for another
variant of IvyBridge.
Given the severity of the stability fixes, I strongly recommend everybody
to upgrade to 2.19.0.
-Chris
* Prevent waiting on scanlines whilst not in control of the VT and therefore
whilst referencing foreign CRTC configurations.
* Pixmap (and bo leak) during fallback glyph composition
* Remove broken acceleration for rendering glyphs directly upon the
destination pixmap, exposed by cairo-1.12.0 (and coincidentally fix
another Pixmap leak upon fallback handling).
* Add support for Ivy Bridge GT2 Server chipset [PCI id 0x016a]
* Remove broken damage flushing with CompositeRectangles
https://bugs.freedesktop.org/show_bug.cgi?id=32547
* Fix crash upon server start with multiple monitors
https://bugs.freedesktop.org/show_bug.cgi?id=47395
* Fix composition issues resulting from overly aggressive Pixmap reuse
https://bugs.freedesktop.org/show_bug.cgi?id=47345
