This PR is on hold until these features/changes are released to prod.

@nofarblue / @rustd Are these changes in Prod yet?

Prepublication tasks: - Resolve merge conflicts - Update release notes (either in this PR or move them to a separate PR)

LGTM. I will make a few style changes in local. I will wait to merge until the On Hold label is removed.

Not sure if you intended to address this in a subsequent PR or if it wasn't relevant, but there is some broken syntax, for example: In any case, @SiyaoIsHiding, please...

> Note that we're only updating links to the manual + Javadoc for 4.x... we're not planning on retroactively fixing older releases. It seems entirely reasonable to expect that since...

I don't want to derail this PR - I will message you on Slack to explain.

@mendonk Can this be merged or is it waiting? There will be MC when I break up the examples page.
