Arriving in time before the holiday season, Mesa 19.3 has now been officially released giving all open source Linux graphics drivers some big boosts and new features.
What is Mesa? Is it a tasty biscuit? Do I have Mesa? If you have an AMD or Intel GPU then yes, you will be using Mesa (unless you changed it, 99% of distributions come with Mesa out of the box) and it's what powers your GPU enabling it to talk to OpenGL and Vulkan.
Don't be too hasty to upgrade right away though, with brand new releases there's always a few gremlins hiding ready to crash your games. The Mesa team always suggest waiting for the first point release 19.3.1 if you're concerned with stability and reliability.
If you're looking for a user-friendly list of what's new, the official 19.3 release notes are not the droids you're looking for. Thankfully, Phoronix has their usual feature overview. In this release you can expect support for the new ACO shader compiler which Valve funded, OpenGL 4.6 support for Intel GPUs, many more Vulkan extensions support added, support for newer AMD and Intel GPUs, bug fixes, performance improvements and so on.
