Free-threaded wheels for Python 3.15t #1509
Description
Python 3.15.0 is out. netCDF4 1.7.4's cp311-abi3 wheels cover regular 3.15, but there are no wheels for free-threaded 3.15t, since the limited API doesn't support free-threaded builds. 3.14t wheels were added in #1459.
.github/workflows/cibuildwheel.yml sets CIBW_BUILD=cp310-* cp311-* cp314-* cp314t-*, so adding cp315t-* would probably be enough.
Activity
add python 3.15 free-threaded wheels (issue #1509)

the 1.7.5 release will include FT wheels for 3.14 and 3.15 (as does cftime 1.6.6.1).
I wonder if we should remove python 3.10 for this release, since it reaches EOL at the end of this month? cftime 1.6.6.1 does not have python 3.10 wheels.

Do you think you could manage to include hdf >=2.2.1 if it comes out soonish and hopefully includes this patch: HDFGroup/hdf5#6722.
We had multiple users complain to us about segfaults.
But I guess conda users will get the HDf patch unrelated to this release, so it's not a strong blocker :)
Thanks!
