Hello,
I've merged the main part of PEP-652 implementation. The Limited C API
(introduced in PEP 384 and used for extension modules that work across
Python versions without recompilation) is now explicitly defined and
better tested.
When changing/extending the limited API:
- Stop and think! This API will need to be suppported forever (or until
Python 3 reaches end of life, if that comes sooner). A checklist of what
to think about is being added to the devguide [0].
- Add/change an entry in `Misc/stable_abi.txt`.
- Run `make regen-limited-abi` [sic].
You can run related checks with `make check-limited-abi`. If that or the
"Check if generated files are up to date" CI test gives you errors,
please let me know!
More tests & docs are coming up.
