Mesa stable users tend to wait often until the xx.y.1 point release before switching to a new stable series. Mesa 22.2 released back on 20 September and once again fell off the release train from its usual bi-weekly point releases, but last night saw that overdue update. Current Mesa release manager Dylan Baker commented:
"I'm a bit late getting this out, I blame XDC. Anyway. This is pretty much what *should* have been in 22.21, with a few extras, so there will be a regularly scheduled 22.2 release next week."
Included in Mesa 22.2.1 are dozens of fixes touching RADV + ACO, NIR, Gallium3D core code, Virgl, LLVMpipe, Zink, and many other fixes across the board. As Dylan put it in the 22.2.1 release announcement , " All in all, lots of good fixes all over the tree. "
