  The AER does not publish a dated changelog of its own. Change happens in two places: the
  Data Standards Body versions the binding contract (releases below), and the AER posts endpoint
  version transitions in the "Supported API Versions" block on its documentation page. Both
  are recorded here; the entries attributed to the AER are the only provider-published change
  notices found.

  detail: >-
    Field-level change requests do not go to the AER. Its FAQ routes them to the Data Standards
    Body change-request process, because "the fields are governed by the Consumer Data Standards".
