[Heads up] test_invalid_regex fails with Python 3.13.0a3 (re.Error renamed to PatternError)

Thanks for the report. Is this packaging with 3.13 or just a local dev build?

Upstream in PyO3 I haven't attempted to support 3.13 yet, so while it's nice to see it "works" I'd be fearful that other stuff might be subtly broken too. I intend to make it more clear to users what the expected outcome is: PyO3/pyo3#3555

That's a part of an early effort to integrate Python 3.13 into Fedora - we package everything with the consecutive alpha releases to provide the early feedback all the interested parties. It's not yet intended as a distribution package heading to the users, but the sooner we've got pydantic-core working, the sooner we can build packages that depend on it.

Understood, thanks. Looks like 3.13 is on GitHub actions, so we could begin testing it and at least trying to make it do sensible things. I wouldn't bet on it being reliable until I've had some time to try to get PyO3 synchronized.
