Mesa 25.3.1 released
Dylan Baker announced Mesa 25.3.1 recently, which is a new feature update for this open-source graphics project. The changes from the previous version (25.3.0) are in this latest release, even though there was no official announcement.
So, what can users expect? Several improvements are spread across different drivers and parts of the system. The big thing is that VDPAU support is gone. It was removed because it had some design issues and wasn't widely available to begin with. Basically, if you're seeking that specific option, it's out.
For NVIDIA graphics card users specifically, 25.3.1 comes with OpenGL acceleration built-in, aimed at recent GPUs. To get this working, you need Zink or NVK enabled during setup; add Zink to the gallium-drivers bit and NVK to the vulkan-drivers part, or set both to auto if your hardware supports it. This feature change means that these newer NVIDIA cards will no longer default to pure software rendering, instead aiming for faster OpenGL performance from the start, provided Mesa's acceleration components are not already installed.
Elsewhere, RADV_DEBUG options have seen some updates too. Future releases will phase out some specific options, so don't get excited if you see them mentioned.
Then there's the PowerVR Vulkan driver update. It now has official conformance for Vulkan 1.0 working on certain GPUs, which is good news. But it also says it supports Vulkan 1.2 on specific hardware, even though full compliance with that version isn't complete yet, just partial support.
You can download the source code of Mesa 25.3.1 from here. If the new release doesn't play nice with your system or graphics card and you run into problems, hit up the project's issue tracker.
The next planned bugfix is set for December 17th.
