 - Added a `secondary_entity` property to the [GET /account/events](/api/v4/account-events) and [GET /account/events/{eventId}](/api/v4/account-events-event-id) endpoints. A `secondary_entity` object displays information about an additional entity that is related to the Event. Currently, the `linode_boot`, `linode_create`, and `linode_clone` Event actions can generate a `secondary_entity` object of type `linode`, `image`, and `backup`.
 
+- Added convenience Object Storage beta endpoints for the Early Access Program. It is recommended to use the more fully-featured [S3 API](https://docs.ceph.com/docs/mimic/radosgw/s3/#) directly instead of these endpoints. **Note**: these endpoints are prepended with **`/v4beta`** instead of `/v4`.
