FYI, new_release.py is tripping on sigmavirus24/github3.py#1105. I (locally) added "usockets" to the ignore list (the last release was September 2021) to get past this, but it's possibly going to be a recurring issue.

All of the work is either already merged, or filed as acute issues. We don't need an overall tracking bug, so I'll close this now.
