<Tip>
  **Breaking changes to the Developer API will always be announced at least 30 days in advance** with a migration guide, a deprecation timeline, and a parallel compatibility period. We will never silently break a stable endpoint. Subscribe to the [developer changelog feed](#) or the developer mailing list (sign up at [surchi.io/developers](https://surchi.io/developers)) to receive advance notice of breaking changes directly.
