As a general rule I think we should acknowledge when significant contribtions come from outside the core team. We know the core team does a lot of work (thank you!) but it's not always obvious when significant contributions come from outside the core team.

In the old change log, we had ACKs via [radarhere] syntax which I miss. I don't expect we'll start using the old change log again but maybe we can make a note in the release notes to include such ACKs as needed and appropriate.

Fixes missing acknowledgments.
