Looks like there are currently incompatibilities with cffi under Python 3.13: https://github.com/python-cffi/cffi/issues/77 We will need to await their next release which is imminent.

looks like they've got it resolved. but rebasing doesn't seem to work still

Apparently it was fixed, but the release is still pending.

cffi==1.17.0 has been released, which helps a lot.

Now it turns out that Python 3.13 modifies the behaviour of argparse --help: https://github.com/python/cpython/pull/103372. I have updated relevant tests accordingly. Please let me know, if we need to keep the tests for Python 3.12 and earlier.

There is also a single failing test caused by the removal of pipes in Python 3.13: https://github.com/pre-commit/mirrors-prettier is no longer maintained, but used in test_bump_pre_commit_changelog. I have marked that test as skip for the time being. IMO, the test should be modified to avoid mirrors-prettier, independent of Python 3.13 support.
