  QC Ware does not publish a dedicated API changelog or release-notes feed. Product changes are announced as
  dated "Product Updates" posts on the Promethium blog. These are product-level, not API-version-level: none of
  them carries an API version number, a breaking-change flag, or a migration note. The REST API itself is on a
  /v0 path prefix with a "v1" payload version field and has published no version history. The most recent
  Product Updates post found is from 2025-01-27; the cadence was roughly monthly through 2024 and has since
  lapsed.
