Note denoting where macros are defined in "API and ABI Versioning" docs was removed accidentally

[dkogan]

Hello. In 3.13, this doc page: https://docs.python.org/3.13/c-api/apiabiversion.html said this at the end: All the given macros are defined in Include/patchlevel.h

In 3.14, this note was removed: https://docs.python.org/3.14/c-api/apiabiversion.html

The commit that removed this makes it look like an accident: 1439b81

That note was present for a long time. If #include <patchlevel.h> is no longer suggested to get the versions, those docs should mention it. If it is still suggested, the note should be put back.

Thanks.

For the record, I would prefer that #including this was still supported. It's sometimes necessary to know the python version before #including <Python.h>, for instance when deciding whether to request the limited api or not.

It was unintentional; thanks for spotting it!
It no longer applies to the whole docs page; I forgot to add it to the section.

That depends on what you mean by “supported”.
I don't think there are any tests for it.
