Mesa 21.0.1 Released, 20.3.5 Issued To Close Out The Older Series
Mesa 21.0 released two weeks ago while now 21.0.1 is out with all the early fixes to that quite big feature update for OpenGL and Vulkan drivers.
Besides continuous integration updates and other maintenance items, Mesa 21.0.1 has a number of Intel driver fixes for both their OpenGL and Vulkan components, a few RADV and ACO fixes, and some Zink and Lavapipe activity as well. This isn't the biggest ".1" release in recent times by any stretch but overall pointing to that Mesa 21.0.x should now be in good shape for upgrading to if you haven't already done so for your open-source Linux GPU user-space driver needs.
See the release announcement for more details on Mesa 21.0.1.
Meanwhile, Mesa 20.3.5 was also released. Now that Mesa 21.0.1 is out, no further updates to Mesa 20.3 are planned. Mesa 20.3.5 brings a number of fixes especially on the RADV/ACO front but also fixes for the Intel ANV Vulkan driver, Panfrost Gallium3D, NIR, and other fixes.
Mesa 21.1 meanwhile is the Q2 feature release that has been in development since January and its branching will get underway next month with hopes of being out by mid-May.
