# Temporal Engine API history

> Operations added or removed in the Temporal Engine API surface, derived from the spec's own revision history — the API's changelog, distinct from the docs changelog.

Derived from the revision history of `spec/temporal.json` (`node scripts/api-history.mjs`).

<Note>
  An operation listed as **removed** was retired from the published surface — a caller still using
  it must migrate, not merely re-read the docs. Added operations link to their reference pages.
