### Documents

* 🍃 **Stop backfilling `extraction-responses` into `extraction-results`**: For API versions before `2021-08-18`, the `extraction-results` attribute on Document responses was being synthetically computed from `extraction-responses`. This backwards-compatibility behavior has been removed. If you are on an API version before `2021-08-18` and rely on `extraction-results`, please use the `extraction-responses` attribute instead.

* 🍃 **Remove non-GET Document endpoint documentation**: The create, update, and submit endpoints for Documents have been removed from the API reference. These endpoints are deprecated in favor of [Transactions](https://docs.withpersona.com/api-reference/transactions). The GET endpoints (retrieve and list) remain available.
