@wyfo Would you mind taking a look at this one? I decided to do all of these changes in a single PR to avoid having to merge and rebase multiple different ones.

Thank you very much! I planned to tackle 3.13 support this weekend, and I'm more than happy to have your PR to start! A single PR is perfectly fine.

@wyfo Would you mind doing a new release? It would be awesome to have compiled wheels ready in time for the 3.13 release.
