DEP: CPython 3.14 compatibility tracker issue #18124
Description
Cpython 3.14.0b1 shipped last week and numpy-dev explicitly supports it already (though they do not ship nightly wheels yet), so I started testing it locally, and found 3 failing tests, all with very different failure modes. I'll open separate (sub)issues here and upstream for each of them. More issues might show up in later stages when more of our dependencies (including optional ones) support this new Python. This issue is about tracking overall progress and will be updated as needed.

Thanks for future proofing!

We're now compatible with beta 2, in the limit of what's already testable.
I'm going to add new subissues to track upstream blockers to enable continuous testing and wheel builds.

There are no known compatibility issues remaining, and we are continously building and testing wheels for this target now. Closing as completed.
