Mesa 21.2.6 Released As Likely The Last Of The Series
Mesa 21.2.6 ships with various Intel OpenGL/Vulkan driver fixes, a few RadeonSI fixes, continued compatibility improvements for the Zink OpenGL-on-Vulkan, a few ACO compiler back-end fixes, and other minor fixes throughout. The Zink changes are perhaps most significant and then mostly the other usual AMD and Intel fixing churn.
Mesa 21.2.6 isn't all that big but one last hurrah for those not yet migrating to Mesa 21.3 as the current stable feature release series until Mesa 22.0 in Q1.
The list of Mesa 21.2.6 patches in full can be found via the release announcement.
