As discussed with @pablogsal , this is a meta-issue for coordinating an editing pass on the What's New in Python 3.11 document.

The focus with this issue and its accompanying PRs will be on textual and reST/Sphinx fixes and improvements to the existing content, rather than adding any missing NEWS entries, or touching the organization of the document itself. Another issue, #95914 , will cover adding the PEPs not currently listed to the Summary - Release highlights section, as well as a few PEPs that are not documented at all in What's New, but probably should be somewhere (PEP-624, PEP-654 and PEP-670).

It seems best to split this into separate PRs, one for each top-level section. I've listed them here for reference, with PRs linked as they are submitted:
