@Yhg1s Would you rather wait until 3.12.1 for this?

If so, shall we also hold off merging it to main and 3.11 until then?

[hugovk]

3.12.1 will be the next release, we're good to merge this now.

@AA-Turner Would you like to use your new powers to click the big green button? :)

[hugovk]

Let's not wait any longer. Thanks for the PR!

Sorry, @AA-Turner and @hugovk, I could not cleanly backport this to 3.11 due to a conflict.
Please backport using cherry_picker on command line.

@AA-Turner sphinx-lint complains about the trailing whitespaces here and here, and if I remove these whitespace in the translation (po file), the HTML ends up like this: (no spaces in-between)

and so on

Could we remove these trailing whitespaces here, and insert them at the beginning of Limited API and Stable ABI?

We can remove all the whitespaces (leading and trailing) in the template file and modify c_annotations.py to handle the spacing.
