Subject: [PATCH] Improve 9.5 release notes.
1) Add sgml comments referencing commits. This is useful to search for
missing items etc.
The comments containing the commit notes are an excerpt from:
git log --date=short \
--pretty='format:%cd [%h] %<(8,trunc)%cN: %<(48,trunc)%s%n%n%w(,4,4)%b%n' \
$(git merge-base origin/master upstream/REL9_4_STABLE)..origin/master
2) Improve a handful of existing notes
3) Add missing entries about a couple features.
4) Add a bunch of straight-forward FIXMEs
