This is a patch release, with only a few isolated changes. Only revdeps are failing, of which I spot checked a few and skimmed the rest, and see no obvious issues. There are also fewer revdeps checks failing in this release compared to the last (#29216) (probably a result of recent archiving?).

I think this should be OK to merge.

Thanks!

I think we forgot to mention this, but 3.21.1 works with current OxCaml.

Definitely room for improvement in the review of feature additions to ensure they include the correct changelog entries :)

Thanks for the merge!
