Why is the macOS 11/12 wheel dropped?

Is there a reason why bcrypt dropped building for macOS 11/12? (see 8995a80) Note that this is between 4.0.1 and 4.1.0 and it's not in the changelog.

Some of our jobs tests on older macOSs (namely the latest 3 versions which includes macOS 12), suddenly all failed because it needs to build from source.

What version of pip are you installing with?

[nelsyeung]

23.3.1 our pipeline always runs pip install -U pip setuptools before installing dependencies.

I'm fairly sure that it's macOS 11/12 wheel is dropped. Correct me if I'm wrong, the commit I linked changed from:

runs-on: macos-11

to

needs: [sdist]
runs-on: macos-13

So that the build now outputs bcrypt-4.1.1-cp37-abi3-macosx_13_0_universal2.whl (See https://pypi.org/project/bcrypt/#files).

pip can't match macosx_13_0 to macOS 12, only macOS 13 or higher. Hence, the previously supported macOS 11+ is dropped.

Ugh, I see the problem. It's a bad transposition of some code from pyca/cryptography.
