Please check for accuracy, glaring omissions, confusing phrases, and typos.

One of the bigger-ticket bugs is:

* Fix a self-deadlock that could occur while replaying WAL generated by an older
minor version. This regression, introduced in the previous set of minor
releases, could cause a standby server following a primary running an older
minor version to become stuck.

Contrary to what you say at the top of the list, this doesn't affect
v18, only v14-v16.  I think this one is definitely important enough
to mention, but maybe put it separately from the main list?
The list was generated from my build of the v18 release notes, and this was in there - though I found the commit message that did confirm it's only v14-16.

Agree it deserves a special callout (I also remember this issue when it was reported) - but do you want to remove it also from the 18.5 release notes? (I checked release-18.sgml and couldn't find it).
