# Changes to Publish a new calibration template version for a tool. Template versions are append-only and
immutable: this becomes the tool's new latest version, prior versions remain readable history,
and existing calibration records stay pinned to the version they were measured against.
Reference gages never take a calibration template. Publishes are not idempotent: a retried
request publishes another version — check the latest version before re-sending after a timeout.
