Reminder: to make releases easier to summarize and test, we should put a
"Fix Bug NNNNNN ___" on the first line of our commit message(s). That
way we can scan thru the CI-generate changeset (e.g.,
https://ci.mozilla.org/job/mdn-next/11/changes) to see exactly which bug
numbers are releasing with the 'next' release.
