    LINE states availability information is provided in English and is not a

versioning:
  scheme: mixed
  api_scheme: uri-path
  detail: >-
    Server APIs are versioned in the URI path, per-API rather than
    platform-wide: /v2/bot (Messaging, Insight, Manage Audience, Module),
    /oauth2/v2.1 (JWT-assertion channel tokens and LINE Login), /oauth2/v3
    (stateless channel token), /v2/oauth (legacy channel token), /liff/v1
    (LIFF server API), /shop/v3 (Mission Sticker). Four version generations run
    concurrently on api.line.me.
  client_scheme: semver
  client_detail: >-
    The LIFF client SDK follows Semantic Versioning from v2.2.0 onward — MAJOR
    for backwards-incompatible public API changes, MINOR for backwards-
    compatible functionality, PATCH for backwards-compatible bug fixes.
  current_versions:
    messaging_api: v2
    channel_access_token: v2.0 / v2.1 / v3
    liff_server_api: v1
    liff_sdk: 2.29.2 (released 2026-07-31)
  policy_url: https://developers.line.biz/en/docs/liff/versioning-policy/
deprecation:
  policy_published: true
  scope: >-
    A formal, dated lifecycle policy exists for the LIFF SDK MAJOR versions. No
    equivalent written deprecation policy is published for the server APIs
    (Messaging, Insight, Manage Audience); server-side changes and removals are
    announced through the LINE Developers news feed instead.
  policy_url: https://developers.line.biz/en/docs/liff/versioning-policy/#life-cycle
  stages:
    - stage: Active
      support: New features added and existing features improved.
      period: From the MAJOR release date to the release of the next MAJOR version.
    - stage: Maintaining
      support: Bug fixes and security improvements only.
      period: 12 months after the Active period.
    - stage: Deprecated
      support: No longer updated, still served.
      period: 6 months after the Maintaining period.
    - stage: End-of-life
      support: >-
        CDN edge and fixed paths are invalidated without notice; apps using that
        MAJOR version stop opening.
