Mesa 25.3 is out tonight as the newest quarterly feature release to this set of (predominantly) OpenGL and Vulkan drivers widely used across Linux systems. Mesa 25.3 features numerous Vulkan extensions added to the different open-source drivers, continued enhancements to the OpenGL drivers, and various other changes.
Mesa 25.3 adds a Gallium driver for Arm Ethos NPUs for use with the Teflon framework, mesh shader support for Zink, various AMD video acceleration improvements, the PowerVR Vulkan driver now exposes Vulkan 1.2 support, SPIR-V shader replacement feature for Mesa Vulkan drivers, OpenCL semaphores for the Rusticl driver, Vulkan AMD Anti-Lag support, Vulkan WSI support for atomic mode-setting, Intel Wildcat Lake support, continued RADV ray-tracing optimizations, and numerous performance improvements at large across the prominent Intel / AMD / NVK drivers and others.
Mesa 25.3 also drops the VDPAU front-end, NVK is more capable than prior releases for that open-source NVIDIA Vulkan driver, and other routine changes round out this quarter’s feature release.
The Mesa 25.3 mailing list announcement has yet to be sent out but for those rolling their own builds can grab Mesa 25.3.0 right now from FreeDesktop.org GitLab.
