Mesa 23.1 was released 12 hours ago. While the patch notes haven’t been posted yet, we can get a glimpse of what’s new with this massive update thanks to the article from Phoronix:

Arch users will likely get this update almost immediately. Fedora users may have to wait a while. And hopefully SteamOS 3.5 will get this upgrade soon, as Steam Deck users will especially benefit from this.
