Increase Python version checked my mypy in CI - #123

My plan is to switch CI to use the Debian 12 which ships mypy that can check for Python 3.9.

The next major version will probably increase the Python version to 3.10 or 3.11 anyway.

Oh, I see. If you want to stick with mypy 1.9, why not just use ubuntu-24.04 as the lint runner? It seems to have the right version: https://packages.ubuntu.com/noble/mypy

Never mind, apparently it somehow doesn't...

Because the mypy is installed from PyPI. I am working on updating the CI including the checkout action versions which are no longer supported.

I think I've found a nice way to pin mypy to it last pre-2.0 version

Maybe that approach works well for your CI update branch?

CI is passing in my branch: 5a58c17

I will merge it and create a new 0.14.3 release.

Alright, thank you! I'll close this one then

0.14.3 released
