Changelog

API changes, deprecations, and version history.

Versioning policy

  • The API is versioned in the path: /v1/
  • Within a version, changes are backward-compatible only: new fields, new enum values, new endpoints
  • Breaking changes ship under a new version path with a deprecation window for the old one
  • Treat unknown enum values and new fields gracefully: they are not breaking

Deprecation process

  1. The field/endpoint is marked deprecated in the changelog and docs
  2. A Sunset header appears on responses for the deprecated surface
  3. After the announced window, it is removed under the next version
