Your patch now has two separate items for "[5c1b66280] Rework design
of functions in pg_walinspect", but even one item is arguably one too
many. The "ending LSN" item (the second item for this same commit)
should probably be removed altogether. If you're going to keep the
sentences that appear under that second item, then it should at least
be consolidated with the first item, in order that commit 5c1b66280
isn't listed twice.
Note also that the patch doesn't remove a remaining reference to an
update in how pg_get_wal_block_info() works, which (as I've said) is a
brand new function as far as users are concerned. Users don't need to
hear that it has been updated, since these release notes will also be
the first time they've been presented with any information about
pg_get_wal_block_info(). (This isn't very important; again, I suggest
that you avoid saying anything about any specific function, even if
you feel strongly that the "ending LSN" issue must be spelled out like
this.)

The wording for this item as it appears in the patch is: "Improve
descriptions of pg_walinspect WAL record descriptions". I suggest the
following wording be used instead: "Provide more detailed descriptions
of certain WAL records in the output of pg_walinspect and pg_waldump".
