current_version_note: >-
  AWS versions this API by service API version, not by release. 2016-12-01 has been the only API
  version since general availability; changes ship as additive model updates under it.

cadence_note: >-
  The API reference has recorded exactly one change since April 2024 - the end-of-support notice on
  2025-05-20. The contract is frozen; the changelog is now a retirement log, not a feature log.
