I think this is all that's needed

I need to double-check a few things later, but conceptually, this should be all that's needed since this already wasn't manually manipulating the GIL or relying on it implicitly.

Should be ready to go, wheel built fine and imported fine on beta 1 on linux, and there shouldn't be anything platform specific about this.

Is the action failing here because it is currently unsupported or is there something else going on?

My guess is that those symbols are only available in the beta version of 3.13 onwards, while CI is still using an alpha version. I can at least verify that it doesn't work on 3.13.0a6 on my machine, providing a similar message.

[mikeshardmind]

Was added after alpha1, but before beta1: python/cpython#116882 CI needs to be updated I guess, idk if that should be part of the same pull or not, I can do that one way or another.

Happy to discuss a bit more, but if you could rebase from main with the updated CI we can ensure these checks run a-ok before a merge.

[mikeshardmind]

rebased over main, but this likely shouldn't be merged until it can be confirmed that this will build properly under the free-threaded builds, which CIBW won't support until beta2

Free-threading mode is not available yet, waiting on official binaries (planned for beta 2) and pip support.
While CPython is in beta, the ABI can change, so your wheels might not be compatible with the final release. For this reason, we don't recommend distributing wheels until RC1, at which point 3.13 will be available in cibuildwheel without the flag.

Looks like pypa/cibuildwheel#1854 was merged and I updated to include that. This should be good to merge now if you're happy with it?

[mikeshardmind]

should be fine from everything I'm aware of for this.
