## Partial event updates

`PATCH /events/{event_id}/` updates only the fields you send, without re-sending the full event. See [Partially update an event](/docs/events#partially-update-an-event).

## Order validation and revenue

* `POST /orders/` now returns `422` when an order references an event that doesn't exist in Hive yet, instead of accepting it.
* Orders with duplicate `item_id` values are rejected with `422`.
* Refunded and transferred tickets are no longer counted in order revenue.
