  Versioning, release cadence, status reporting and deprecation posture for the Safari
  developer surface.
versioning:
  scheme: product version, not URL or header
  detail: >-
    Safari APIs version with the browser release. Apple publishes release notes per
    Safari version (currently Safari 26.0 through 26.6, plus Safari 27 Beta) and runs a
    separate Safari Technology Preview train shipping roughly every two weeks (STP 237
    through STP 251 during 2026). Apple Pay JS carries an additional integer API version
    — features such as ApplePayError and the phoneticName contact field require Apple Pay
    API version 3 or later.
  current:
    stable: Safari 26.6
    beta: Safari 27 Beta
    preview: Safari Technology Preview 251

deprecation_policy:
  published: false
  detail: >-
    No dedicated Safari or WebKit API deprecation policy is published, and no Sunset or
    Deprecation response headers (RFC 8594) are documented on any Safari surface. The
    Safari 26.6 release notes carry no Deprecations section. WebKit does publish a
    Feature Policy and per-specification standards positions, but those govern what gets
    implemented, not how implemented API is retired. Recorded as absent rather than
    inferred.

    detail: '"Start Session is being phased out and replaced by Payment Session." No sunset date is published.'
  - name: WebKit Feature Status page
    replacement: MDN and Can I Use for support data; WebKit Standards Positions for specification positions

      Probed 2026-09-07 — HTTP 200, but the body reads "The WebKit Feature status page
      has been retired." A soft-retirement: the URL still resolves. No Roadmap pointer is
      emitted for it for this reason.
sla:
  published: false
  detail: No service level agreement is published for the Apple Web Push service or the Apple Pay gateways.
