Description

This goes a bit above-and-beyond #3852, but I figured I would update everything together.

As mentioned in f8547fb:

NB: We may also want to test ubuntu-22.04 and windows-2022 against both tests and batch-processing, too, just to be prepared for future deprecations.

I wanted to start by testing macos-12 in tests.yml, but we should maybe add additional commits afterwards for these cases, too.

Fixes #3852.

I'm noticing that .github/workflows/tests.yml still contains a bunch of references to ubuntu-18.04, should some of them also be updated to ubuntu-20.04? (Some of them have an explicit comment about wanting to use an older kernel, so probably not those.)

Ah, sorry! My rationale for d6d58e6 wasn't very clear.

For both create-release.yml and test-batch-processing.yml, I wanted the distributions we test to match the "core" set of distributions we test on PRs in tests.yml. I only bumped 18.04 -> 20.04 for test-batch-processing because it was mismatched compared to the other 2.

My thinking is that we would bump the other 18.04-based runners in tests.yml only after GitHub Actions no longer offers it? But, maybe there's a different approach we could use?

As noted in the deprecation announcement, we've entered a 24-hour period where macOS 10.15 runners are unavailable (July 27 from midnight UTC to midnight UTC). This is the missing automated check to merge this PR (after which, we won't be blocked by the automated check for other PRs). I don't have admin privileges for this repo, so I can't bypass it, unfortunately. @joshuacwnewton, would you do the honours?

I think this might also be because macos-10.15 has been removed from the CI workflow entirely?

If I remove this requirement (since it's going to be replaced with macos-11 anyway), this PR should become mergeable without admin privileges. (EDIT: Done!)

And now that the PR is merged, I added macOS 11 as a required check:
