Added

• API versioning is documented - The Admin API is versioned by release date. Send the date of the release your integration was built against in the API-Version request header. Breaking changes ship only in dated releases, and additive changes reach every version. See Versioning for how a version is resolved, the release cadence and the support window.
• API-Deprecated response header - A response to a request that selects a field scheduled for removal names each such field and its removal release, for example API-Deprecated: CurriculumPlan.symbol; removed=2027-01-01. See Deprecation warnings.

Upcoming releases

• 2027-01-01 - CurriculumPlan.symbol is removed. Use currencySymbol.
• 2027-04-01 - Every Unix-timestamp field, argument and filter typed Int / IntOperator moves to BigInt / BigIntOperator. Timestamps already typed BigInt keep their type. BigInt values are serialized as JSON strings, so parse them before comparing or sorting. See Migrating to 2027-04-01.

No release is in effect yet. A request without an API-Version header receives the baseline schema, and an API key, OAuth application or App Installation created on or after 2027-01-01 is pinned to that release automatically.

To test an upcoming release early, send its date in the header, for example API-Version: 2027-04-01. The API accepts any valid YYYY-MM-DD date, including a future date.
