  Sphinx "Change history" page. Each release carries an explicit `release-date` and `release-by`
  field followed by a "What's Changed" list of merged pull requests with issue numbers — dated and
  machine-readable enough to diff between versions. Mirrored as GitHub Releases.

note: >-
  Entry detail beyond 5.6.3 is intentionally left to the provider's own page rather than transcribed
  in bulk — the changelog is long-lived and the recent window is what this artifact is for. Release
  dates for 5.6.0-5.6.2 were read from the GitHub Releases API, which agrees with the docs page.
