[Mesa-dev] Mesa 20.3 status

Hi list, 

Mesa 21.0.0 is now out the door. We're really behind on the 20.3 branch,
but I'm just too exhuasted to try to keep maintaining both branches,
especially with 21.1 coming up, so I'm planning to do one more release
of 20.3.x along with this. You can see the current status of the branch
on githlab. The following are patches that 1) don't apply cleaningly, 2)
don't compile, or 3) cause regressions in the CI.

I'm hoping to make the final release (barring any pressing regressions
in this release) next wedensday. If you see something in here that you
want to see in that release, please create an MR agianst the
staging/20.3 branch.


P.S. If you're interested in helping with releases, I'd love to talk
with you about it :)
