The latest in open source graphics drivers for Linux has released, with Mesa 20.1.0 now out with tons of changes and improvements everywhere.
With this being the first release of a new branch, the Mesa team do advise you either stick with your current Mesa version or wait at least until Mesa 20.1.1 when they clean up any pressing issues. Mesa 20.1.1 is current scheduled for June 10. The first big new release is usually classed as a development release.
Some of the new features include:
- Vulkan device selection for multi-GPU environments
- Support for more OpenGL and Vulkan extensions across various drivers
- Many performance improvements across all drivers (including improvements to their OpenGL threading)
- Support for newer GPUs

They're already aware of one major issue with Unreal Engine 4, which appears to use glDrawRangeElements incorrectly and Mesa doesn't yet have a workaround. More info on that here.
