[Rd] Convenience Request: Add revision numbers to "What's New" change list

[Avraham Adler]

Hello.

When deciding whether or not to update an R installation—either
patched or devel—I think it would be valuable to see the revisions in
which the updates/patches were applied. For those with linked PRs, if
one has a Bugzilla account, one can often find the revision in the
final note; however, not everyone has a Bugzilla account. This is a
very minor request, of course, solely a quality-of-life issue, but I
think it would be appreciated.

Thank you,

Avi
