3.0.0-release_20211229

It's been a while!

Errata

Since it's been a while, I (@nwf) had forgotten how to do a release correctly. For approximately 18 hours, the release branch pointed to 35b850e rather than the correct commit, 0b97855. These commits are tree-identical but have differing histories. If you ended up on the former, please fetch and rebase to the latter.

Breaking Changes

None expected.

New Modules

None.

Bug Fixes

Please see the release milestone for details.

Deprecation

The master branch has been updated (by merging release) but this is likely the last release where that will be true.
