Requested Feature

Python 3.12 has entered beta, so it's a good time to start thinking about Sopel on that version.

• Check Sopel tests against 3.12 (done in Add Python 3.12 support #2516)
  • Installing dev-requirements.txt was blocked by lack of support in greenlet, but a PR has since been merged with a fix for this, presumably the next release will include that fix.
  • Looks like we may need to adjust the version requirement for setuptools, I see the following error with setuptools == 67.8.0 but pinning setuptools < 67 in build-system.requires resolves it.

  AttributeError: module 'pkgutil' has no attribute 'ImpImporter'. Did you mean: 'zipimporter'?
  

  • There was additional upstream breakage that has now been fixed in aiohttp (fixed on develop, should be included in 3.9) and in frozenlist (released in 1.4.0)
• Update CI to run with 3.12 (done in Add Python 3.12 support #2516)
  • Looks like the python-versions Action is capable of providing the 3.12.0b1 pre-release, so we could run against the beta version(s) before the official release (scheduled for 2 October 2023).
• Update classifiers list in pyproject.toml (done in Add Python 3.12 support #2516)
• [ ] Check on 3.12 support concerns for official non-core plugins Not core's problem — @dgw
