No win32 wheel for Python3.14

[jiasli]

Thanks for supporting Python 3.14 (#864). However, it seems to be a deliberate decision that Python 3.14 win32 package is dropped (#864 (comment), #888 (comment)):

pyyaml/.github/workflows/ci.yaml

Line 574 in d51d8a1

# no more win32 after 3.13?

This breaks Azure CLI's build process with an embedded Python and PyYAML must be built from source.

Python 3.14 still releases Windows installer (32-bit): https://www.python.org/downloads/release/python-3145/

I am raising this issue to check if this is really a deliberate decision. If so, it is better to document it in CHANGES:

pyyaml/CHANGES

Lines 6 to 12 in d51d8a1

	7.0.0.dev0 (TBD)
	* TBD
	6.0.2 (2024-08-06)
	* https://github.com/yaml/pyyaml/pull/808 -- Support for Cython 3.x and Python 3.13

CHANGES now lacks an entry for 6.0.3.

@nitzmahone Can you speak to this?

Cheers!

This was a purposeful decision at the time 3.14 support was added, due to the influx of requests for additional arches and the original multiplicative effect of the t ABI- many other projects have dropped 32bit x86 support on all platforms.

That said, now that abi3/abi3t support looks to be workable for Cython extensions, I'm willing to revisit. There were some minor lingering Cython issues when I checked a few weeks back, but I'm willing to keep win32 CPython wheels and testing in the mix as long as:

• abi3/abi3t support remains workable for it under Cython/pip/setuptools/cibuildwheel/GHA
• Win32 installers remain tier-1 supported for CPython

The next PyYAML release on PyPI will likely ship exclusively abi3/abi3t wheels, so this should be available within the next few weeks.
