mesa-25.1.2

[Bruce Dubbs]

New minor version. Perhaps we should get on a schedule and only update mesa once a month.

[Bruce Dubbs]

There have been 9 releases this year (in 127 days). We need to treat this like poppler and update once a month.

[zeckma]

I'd like to propose two different potential schedules.

1. Whenever a new minor releases, per usual, we update to xx.x.1, then wait for either the next minor or final point release, then update to that, like how we handle LLVM with major releases.
2. When a new minor releases, we just wait for the last point, then update to that so all bugs get fixed and users can have a more stable experience. In that case, users who want a more newer experience can go out of their way with trying the newest mesa version. Going about it that way will require editing the note on the Mesa page, however.

Both LLVM and Mesa release plans have maintenance releases at two week intervals. At this stage of maturity most of the Mesa work does not affect x86_64 graphics. So a plan like LLVM or a time based plan like Poppler would make sense and there is always the ability to pick up any update if there is a major problem with x86_64.

My workflow will continue to do every release and can flag something I see in the release notes.

We already have the note that mesa updates quite frequently and to use the latest version from mesa-git. AFAIK mesa build instructions haven't changed much and we haven't had a breaking change in a while.

Now 25.1.1.

[zeckma]

New bugfix release.

[Bruce Dubbs]

It is now June.
