Thanks for your contribution! PyO3 drops support for Python 3.9 and 3.10 which we'd like to keep around for a bit longer.

I'm well aware these versions are end of life, but they still make up a significant amount of our downloads, so they'll stay first class citizens for a bit longer.

That’s reasonable enough! This PR will still be available when you need it, and I’ll be carrying it as a downstream patch in Fedora, since we don’t benefit from supporting end-of-life interpreters, but we do benefit from the improved Python 3.14 support in PyO3 0.26 and later, and it’s my understanding, though I can’t dig up a link right now, that versions of PyO3 prior to 0.26 are also expected to have issues with a future LLVM release.

Amended my comment above; I was mixing up PyO3 and bindgen with respect to LLVM compatibility.

Hi, I think this might be a misreading of the PyO3 changelog. PyO3 dropped support for pypy 3.9 and 3.10, not Python 3.9 and 3.10.

I doubt pypy 3.9 and 3.10 are a big fraction of your downloads. Unfortunately pypistats doesn't break stats out between CPython and pypy.

I think I might go ahead and open a new PR based on this one that updates to PyO3 0.28, which automatically declares support for the free-threaded build in the extension. PyO3 0.28 still supports Python 3.8 and 3.9.

You're absolutely correct. I misread the release notes. We can go ahead and upgrade PyO3.

Sorry for unnecessarily holding this back @musicinmybrain, I misread the release notes. Thanks again for opening this PR!

Closing in favor of #60

Thanks!
