versioning:
  scheme: date-based
  mechanism: X-GitHub-Api-Version request header
  current: '2022-11-28'
  docs: https://docs.github.com/en/rest/about-the-rest-api/api-versions
  notes: >-
    GitHub versions the REST API by date via the X-GitHub-Api-Version header.
    When a new version ships, older versions remain supported for a deprecation
    window; requests without the header default to the oldest supported version.
deprecation:
  policy_url: https://docs.github.com/en/rest/overview/breaking-changes
  changelog: https://github.blog/changelog/label/copilot/
  sunset_header: false
  notes: >-
    Breaking changes are announced ahead of time on the GitHub changelog and
    surfaced by pinning to a dated X-GitHub-Api-Version, rather than via RFC 8594
    Sunset/Deprecation response headers.

  note: >-
    Per the GitHub blog (2026-04), GitHub Copilot individual plans and billing
    moved to usage-based (premium requests) billing — a commercial lifecycle
    change captured in blogs/ and changelog/github-copilot-changelog.yml, not an
    API-version change.
