note: >-
  DynamoDB has no API changelog in the release-notes sense - the API version has
  not moved since 2012 - so the honest changelog is the developer-guide document
  history, where capability changes are announced. Recent window only; the full
  table runs back to July 2018. Each entry below carries the date AWS printed.
  One thing the window itself says: the table jumps from 31 August 2026 back to
  30 October 2025, so published documentation changes have been sparse over the
  last year even while the contract grew a SearchVectors operation.
