  OpenTravel publishes no product changelog and no release-notes feed. There is no
  /changelog page, no RSS of releases, and the public GitHub mirror of the specifications is
  a single squashed commit ("Initial commit", 2024-11-26) so its history carries no signal
  either. The two dated streams that DO exist are (1) publication announcements on
  /announcements/ and (2) GitHub Releases on the tooling repositories. Both are captured
  below. Entries are recorded with the dates the provider published; nothing is inferred.
