  LINE publishes no single platform-wide API changelog. Change is announced
  across three surfaces: the LINE Developers news feed (all platform APIs, not
  version-tagged), per-SDK release notes pages, and GitHub releases on the
  first-party SDK repositories. The LIFF release notes are the only dated,
  versioned, machine-readable changelog LINE maintains on the developer site,
  so they are the structured record captured here.
surfaces:
  - name: LINE Developers news

    dated: true

    covers: All LINE Platform APIs, including outage reports and policy changes.
    note: >-
      Tag-filtered views exist (e.g. /en/news/tags/outage-report/). Returned
      403 to an unauthenticated non-browser fetch during this pass; the
      individual documentation pages under /en/docs/ serve fine.

    note: >-
      The specification repository is the de facto contract changelog — it
      carries no tagged releases (GitHub releases list is empty), so contract
      change must be read from commits.

  Only version, date and the publisher's own summary are recorded. Where the
  release notes describe internal behavior changes with no feature change, that
  is what is stated — nothing has been inferred about what changed inside.
