# Deprecation policy

> **Placeholder page.** Full content tracked under the docs content effort.

* Additive changes (new endpoints, new optional fields, new enum values appended to **input** enums) are non-breaking and roll out at any time.
* Removing or renaming a field, changing a type, or tightening a validation rule is **breaking** and ships only in a new major version.
* Deprecated fields are marked in the OpenAPI spec with `deprecated: true` and listed here with a sunset date no earlier than 90 days out.
