  AWeber keeps two independently versioned changelogs — one for the REST API and one for
  Webhooks — inside the API reference itself. The API track is still shipping (three releases in
  2025) but the cadence is slow and the entries are almost entirely additive field/parameter
  changes. Recent window captured below; the live page is the source of truth.
