name: AxonFlow API Lifecycle
versioning:
  scheme: semver
  current_platform_version: 11.1.0
  policy: AxonFlow SDKs and the AxonFlow platform are versioned independently but follow a coordinated release cadence. SDKs are backward compatible -- an older SDK works against a newer platform for all features the SDK already supports. SDKs are not forward compatible.
  discovery: GET /health returns version and a capabilities list (since platform v4.8.0 and SDK v3.8.0)
  docs: https://docs.getaxonflow.com/docs/sdk/version-compatibility/
deprecation:
  policy: No formal deprecation window is published. Deprecations are announced in release notes; v11 legacy policy endpoints accept no writes and carry deprecation headers, and X-Tenant-ID is accepted as a deprecated alias that logs a deprecation warning.
  deprecated_operations_in_contract: 90
