@cbkerr For the “oldest” tests, feel free to update the NumPy pinning to the oldest version for which wheels exist for all supported platforms / Python versions. We don’t want to have to compile NumPy from a source dist to run tests.

Also it is okay to drop Python 3.8, if 3.8 presents any challenges here. It has been dropped by NEP 29 / SPEC 0 and will only get security updates through October 2024.

[cbkerr]

I update the oldest numpy to 1.21.0, which is the first one that has an arm build that supports macos 11+.
