description: Decart publishes a dated, month-grouped changelog on its documentation
  host covering model launches, retirements, SDK releases and platform changes. Ten
  months of history were present at capture (October 2025 through July 2026). Entries
  are labelled by month rather than by API version — the REST surface has stayed on
  /v1 while capability changes ship as new model ids.

observations:
- Model retirement is a recurring, announced event (May 2026 and June 2026 each retired
  a named set of models with a stated migration target), but it is announced in the
  changelog rather than governed by a published deprecation window or Sunset header.
- The rolling -latest aliases are the provider's stated forward-compatibility mechanism;
  pinning an explicit model id is the documented way to avoid being moved.
