  Databento maintains dated API and dataset release notes at
  databento.com/docs/release-notes (JS-rendered; the page is the source of
  truth for platform changes, including deprecation/removal windows such as
  timeseries.stream deprecated 2023-03-03, removed after 2023-06-02). The
  official client libraries keep semver CHANGELOGs on GitHub; the Python
  client's recent window is captured below as a verifiable structured sample
  (client releases track platform/DBN changes closely).
