# v1.016

**Documentation-only update.**
Surfaces existing facts in the OpenAPI spec that were previously missing:

* corrects the `required` flag on the `rma` query parameter
* annotates several already-deprecated output fields with `deprecated: true`

***

## 🚀 New Endpoints

*None*

## 📖 Documentation & Constraints Changes

* **Get Return** (`GET /v1/integrations/returns`) — the `rma` query parameter is now correctly marked as `required: true`. No runtime change; the parameter was always required.

* **Deprecated output fields** — `ship_monk_hazmat_carrier_service_not_available`, `tax_id`, `product_type`, `hs_code`, and `sscc` are now explicitly annotated with `deprecated: true` (and the `description` prefixed with `Deprecated: …` where applicable). No runtime change; these fields were already deprecated.
