 Built-in formats are the following.
 
-* `:json` and `:jsonapi`: use object's `to_json` when available, otherwise call `MultiJson.dump`
+* `:json`: use object's `to_json` when available, otherwise call `MultiJson.dump`
 * `:xml`: use object's `to_xml` when available, usually via `MultiXml`, otherwise call `to_s`
 * `:txt`: use object's `to_txt` when available, otherwise `to_s`
 * `:serializable_hash`: use object's `serializable_hash` when available, otherwise fallback to `:json`
+* `:binary`
 
 Use `default_format` to set the fallback format when the format could not be determined from the `Accept` header.
 See below for the order for choosing the API format.

 Upgrading Grape
 ===============
 
+### Upgrading to >= 0.9.1

+#### Changes to content-types
+
+The following content-types have been removed:
+
+* atom (application/atom+xml)
+* rss (application/rss+xml)
+* jsonapi (application/jsonapi)
+
+This is because they have never been properly supported.
