+* The `filter` (singular) query parameter, which was deprecated in favor of the
+  `filters` option in Docker 1.13, has now been removed from the `GET /images/json`
+  endpoint. The parameter remains available when using API version 1.40 or below.
 * `GET /services` now returns `Capabilities` as part of the `ContainerSpec`.
 * `GET /services/{id}` now returns `Capabilities` as part of the `ContainerSpec`.
 * `POST /services/create` now accepts `Capabilities` as part of the `ContainerSpec`.
