We haven't done anything to explicitly support free-threaded Python, and there may well be code and test changes needed to support it.
Shall we at least start running the existing tests on free-threaded?
With cibuildwheel 3.0 in #676, we also get free-threaded 3.14 wheels (see
cp314tat https://github.com/ultrajson/ultrajson/actions/runs/16775927977) which means others will be able to test it further.python/cpython#133779 is also fixed and we can continue testing (regular) 3.14 on Windows.
