  Marketing Cloud Engagement does not publish a dated, per-endpoint API changelog. Changes
  ship on the Salesforce three-releases-a-year train and are described in the Marketing Cloud
  Engagement release notes on Salesforce Help, which is a JavaScript-rendered Lightning page:
  it returns HTTP 200 to curl but the entry list is not present in the returned HTML, so this
  artifact records the scheme and only the entries confirmed from other first-party sources
  (the Salesforce Developers blog and the MCE MCP documentation). Recent-window only; the live
  release notes remain the source of truth.

    Marketing Cloud Engagement REST routes are versioned per product area at v1 and are not
    on the Salesforce Platform numbered API version train (v67.0 etc). A seasonal release
    changes behaviour behind the same v1 routes. See
    lifecycle/salesforce-marketing-cloud-lifecycle.yml.

    The full seasonal release-note history could not be enumerated because the canonical page
    renders client-side. Only entries corroborated by a first-party non-JS source are listed;
    nothing is inferred.
