hm. so the 3.15 final delay presents a little conundrum - are we okay to wait for 3.15 final for our next v4.3 release? It would be nice for 3.15 final to coincide with a feature release of cibuildwheel IMO.

The downside is we don't put out a release of cibuildwheel with this rc3. I think that would be okay since rc1 is the main milestone for cibuildwheel. so options are:

a) cherry pick 3.15rc3 onto a minor version branch and put out a cibuildwheel v4.2.2 version soon
b) just release our cibuildwheel v4.3.0 this week and put out a patch version with 3.15.0 final later
c) wait for 3.15.0 final and release v4.3.0 then

my feeling is (c) - any objections?

my feeling is (b)

Any one of those are fine with me, though I like (b) best. There shouldn’t be any actual difference between the final and RC.

Asked Claude to check on my phone, looks like we have never lined up a final release with a minor bump, always patch.

No — every final .0 CPython update has shipped as a patch release, never a minor bump. That supports option (b) in the thread.

• 3.14.0 → v3.2.1 (Oct 2025): Update to CPython 3.14.0 final ([Bot] Update dependencies #2614)
• 3.13.0 → v2.21.3 (Oct 2024): Update CPython 3.13 to 3.13.0 final release ([Bot] Update dependencies #2032)
• 3.12.0 → v2.16.2 (Oct 2023). It carried a few small features too but was still a patch: Updates CPython 3.12 version to 3.12.0, final release ([Bot] Update dependencies #1635)
• 3.11.0 → v2.11.2 (Oct 2022): Updates CPython 3.11 to 3.11.0 - final release ([Bot] Update dependencies #1327)
• 3.10.0 → v2.1.3 (Oct 2021): Updated CPython 3.10 to the 3.10.0 final release
• 3.9.0 → 1.6.2 (Oct 2020): Python 3.9 updated to the final release version - v3.9.0 (chore: update to 3.9.0 final #440)

The minor bump has always gone with RC1, when the new Python starts building by default. For example, v4.2.0 made CPython 3.15 wheels build by default with 3.15.0rc1, matching v3.1.0, v2.20.0, v2.15.0, v2.9.0 and v2.1.1 in earlier years. The release just before .0 has been a mix. v3.2.0 was a minor release carrying 3.14.0rc3, while v2.16.1 and v2.21.2 were patch releases with rc3. So (b) fits the usual pattern: a v4.3.0 now with rc3, then a v4.3.1 for 3.15.0.

Thanks for the input - on reflection I agree with you guys. I'll do the release now.
