description: >-
  Air Transat publishes no changelog page, release-notes feed or dated updates
  channel for its API. The only version history that exists in public is the
  four-row table printed on page 2 of the specification PDF, transcribed here
  verbatim. It is the entire published change record for the direct-connect
  API, covering 2020 to 2023.

scheme: document-version
current: 2.2.4
current_source: 'cover page: "Version 2.2.4 - Updated: May 2023"'
latest_in_history: 2.2.5
feed: null
page: null
cadence: irregular
window: 2020-09-08 to May 2023

discrepancy:
  observed: >-
    The cover page states version 2.2.4 (May 2023), but the Version History
    table lists 2.2.3 (2023-MAY) and then 2.2.5 with no date, and never lists
    2.2.4 at all.
  impact: >-
    A partner cannot determine from the published document which revision they
    are actually reading, when 2.2.5 shipped, or whether any of the changes
    were breaking. There is no version-support or migration statement anywhere.
