Most changes to Python require a NEWS entry. Add one using the blurb_it web app or the blurb command-line tool.

If this change has little impact on Python users, wait for a maintainer to apply the skip news label instead.

I'm not particularly convinced we need this, but perhaps it's worth considering. cc @picnixz--do you think there's any added clarity here?

[ZeroIntensity]

No need for this, we skip blurb entries for documentation changes--the "Documentation" section is for changes to the docs build.

If It helps here is the documentation preview:
📚 Documentation preview 📚: https://cpython-previews--130817.org.readthedocs.build/

The changed page is to add clarity since there are two pages with different content with the same title:

preview new page

original page

The other page with the same title is this

I'm not sure I'll have time for review today. And I'm leaving for 10 days so I won't be back until the mid/end of next week

@ZeroIntensity You tagged @picnixz--do as it isn't smart enough to split it. (I've made this mistake before too :-)

[StanFromIreland]

@sharktide You do not need to update the branch

(This should be made more clear in the devguide)
