# Versioning

> How the contract evolves.

The API is versioned by path (`/api/v1`) and evolves **additively only**:
fields are added, never renamed, retyped, or removed. Optional request
parameters (like [`view`](/guides/response-shaping)) never change the
schema of a response — they fill or null optional fields.

Treat open vocabularies as open: deal statuses, for example, include the
system set plus any custom statuses your org defines.

Every change ships with a [changelog](/changelog) entry, and the
generated API Reference always reflects the deployed service.
