Mesa 26.2.0 is quite a bumper release bringing a lot of new features across many open source Linux / SteamOS drivers.
As always, the developers suggest you wait until at least Mesa 26.2.1 for any urgent bug fixes if you want a properly stable experience.
Some of what’s new includes the likes of mesh shaders on the open source NVIDIA NVK driver, lots of optimizations to the Intel ANV driver, more new Vulkan extension support across various drivers like AMD RADV and so much more.
Looks to be an exciting release.
