There was a problem hiding this comment.
We don't use allow-preleases. The correct thing to do is specify 3.15-dewv

Python 3.15 is not out yet, but it has entered "release candidate" phase, meaning the ABI and features are now stable. PSF recommends third-party projects maintainers to test and declare support for this version.
This PR adds 3.15 to the classifiers in the setup.py and adds 3.15 to the test matrix. For the latter, I had to add
allow-prereleases: true; it will take prereleases only for versions that hadn't come out yet (3.15 -> 3.15.0rc1) and will become redundant on 2026-10-01
