  HTX maintains a dated change log inside the Spot API reference (entries from
  2018 onward documenting new endpoints, parameter changes and feature
  additions), supplemented by dated support announcements for rate-limit and
  interface changes. Exact recent entry dates were not captured verbatim here;
  the docs change log is the source of truth. The entries below are real,
