Thank you for the speedy turnaround.

All looks good except for the changelog (we don't need one for these types of changes), so I'll go ahead and remove that commit before merging.

fyi: we don't do changelog for non-user facing changes or non-code changes, anything touching only tests/docs/ci, etc.
