observations:
  entry_count: 15
  span: 2021-07-16 to 2026-04-02
  breaking_changes: 5
  cadence: irregular, roughly two to three entries per year
  quality: 'Unusually good for a partner API — every entry is dated, breaking changes are labelled
    as such, and renamed fields are named on both sides of the rename. The weakness is
    distribution, not content: the changelog is only reachable by reading a 3.6 MB Redoc page, has
    no feed, and is not versioned or diffable.'
