Please could markupsafe._speedups declare support (or lack thereof) for free-threaded Python?

[AA-Turner]

When testing a project downstream of markupsafe with python3.13t via deadsnakes, the following warning is emitted:

<frozen importlib._bootstrap>:488
  <frozen importlib._bootstrap>:488: RuntimeWarning: The global interpreter lock (GIL) has been enabled to load module 'markupsafe._speedups', which has not declared that it can run safely without the GIL. To override this behavior and keep the GIL disabled (at your own risk), run with PYTHON_GIL=0 or -Xgil=0.

I haven't had the time to look at the source of _speedups (sorry), but please would it be possible to declare this one way or the other? I resolved this with an axe downstream by simply deleting the compiled extension in CI, but this isn't ideal!

Thanks,
Adam

How? Can you point me to instructions about this or make a PR to review?

[AA-Turner]

I'm on mobile so please excuse the brevity -- there are guides here (https://py-free-threading.github.io/porting/#__tabbed_1_1) on porting, and also on CI testing (https://py-free-threading.github.io/ci/). The CPython docs also have a brief HOWTO (https://docs.python.org/3.14/howto/free-threading-extensions.html).

I'm unlikely to have time to make a PR until mid-September at the earliest, sorry.

Thanks, seems like we need to add a marker and update cibuildwheel. I won't be able to get to this soon either, unfortunately, so anyone who sees this and has time for a PR would be appreciated.
