  OpenX publishes a single dated release-notes page with three tabs. It is a
  product changelog, not an API changelog — the overwhelming majority of entries
  describe UI features in OpenXControl / OpenXExchange / OpenXSelect. Only one
  entry in the captured window is an API contract change (the OpenXSelect
  GraphQL field deprecation). Recent window only; the live page is the source of
  truth. Dates are as printed on the page, which interleaves date markers
  between entries — where an entry's date attribution is ambiguous it is noted.
