npm refuses to implicitly move `latest` to a lower version, so the v0.84.1
publish failed after a clean verify:

  npm error Cannot implicitly apply the "latest" tag because previously
  published version 0.106.0 is higher than the new version 0.84.1.

Backports now publish under release-<major>.<minor>. Dist-tags do not affect
semver range resolution, so a consumer pinned to ^0.84.0 still resolves 0.84.1,
and `latest` keeps pointing at the newest release.
