description: >-
  Ghost versions its HTTP APIs with an Accept-Version request header and a published
  stability index, and versions the platform itself with a major-version LTS ladder that
  states an explicit end-of-life date for every past major. Because Ghost is both
  self-hosted software and a managed service, "deprecation" has two meanings: an endpoint
  marked Deprecated in the stability index, and a major version that has reached EOL and
  should be considered insecure.
versioning:
  scheme: header-negotiated major.minor
  request_header: 'Accept-Version: v{major}.{minor}'
  response_header: 'Content-Version'
  current: v6.0
  docs: https://docs.ghost.org/faq/api-versioning
  semantics: >-
    Accept-Version declares the minimum version of Ghost the client can operate with.
    Ghost answers with Content-Version naming the version of the install that responded.
    When the header is present and the request cannot be served, Ghost emails the site
    owner and administrators with the details so an outdated client is discoverable.
  stability_index:
  - level: stable
    meaning: Forward compatible changes only.
  - level: experimental
    meaning: Being actively worked on; may receive breaking changes.
  - level: deprecated
    meaning: Scheduled for removal.
  note: >-
    All Content API endpoints (posts, pages, tags, authors, tiers, settings) are
    documented as stable.
deprecation:
  policy_published: true
  docs: https://docs.ghost.org/faq/major-versions-lts
  mechanism: >-
    Stability index level on the endpoint, plus a major-version LTS ladder with a stated
    End of Life date per major.
  sunset_header: false
  deprecation_header: false
  rfc8594: false
  guarantee: >-
    Ghost ships a major version every 8-12 months and states that code written against
    the API today is stable for a minimum of two years.
  support_model: >-
    The current major receives features and improvements; the previous major is the LTS
    line and receives only critical security and stability fixes. Past EOL a version
    should be considered insecure.

    status: current
  deprecated_operations: []
  deprecated_operations_note: >-
    No operation in openapi/ carries `deprecated: true`. Ghost documents deprecation on
    the endpoint reference rather than in a machine-readable spec, so absence here is a
    gap in the contract, not evidence that nothing is deprecated.
status_page:
  url: https://status.ghost.org
  status: 200
  scope: >-
    Ghost(Pro) managed hosting. A self-hosted Ghost install is not covered by this page —
    its availability is the operator's own.
  probed: '2026-08-13'
sla:
  published: false
  note: >-
    Ghost publishes no numeric uptime SLA for Ghost(Pro) on its public pricing or terms
    pages, and none exists for self-hosted installs by definition.
