+### BC Breaks
+
+- Configuration:
+    - Rename `[server]` section of Client API HTTP server as `[server.client.http]` ([#33]).
+
 ### Added
 
 - Control API:
-    - Support for static Сontrol API specs ([#28]).
+    - Support for static Сontrol API specs ([#28]);
+    - Dynamic Control API exposed via gRPC ([#33]):
+        - `Create` method for `Room`, `Member`, `Endpoint`;
+        - `Get` method for `Room`, `Member`, `Endpoint`;
+        - `Delete` method for `Room`, `Member`, `Endpoint`.
 - Signalling:
     - Dynamic `Peer`s creation when client connects ([#28]);
     - Auto-removing `Peer`s when `Member` disconnects ([#28]);
     - Filter `SetIceCandidate` messages without `candidate` ([#50](/../../pull/50));
     - Send reason of closing WebSocket connection as [Close](https://tools.ietf.org/html/rfc4566#section-5.14) frame's description ([#58](/../../pull/58)).
+- Configuration:
+    - `[server.control.grpc]` section to configure Control API gRPC server ([#33]);
+    - `server.client.http.public_url` option to configure public URL of Client API HTTP server ([#33]).
 - Testing:
     - E2E tests for signalling ([#28]).

+///
+/// This kind of URI used for pointing to some element in spec ([`Room`],

+/// state.
+///
+/// [`LocalUri`] can be in three states: [`ToRoom`], [`ToMember`],
+/// [`ToRoom`]. This is used for compile time guarantees that some
+/// [`LocalUri`] have all mandatory fields.
+///
+/// You also can take value from [`LocalUri`] without clone, but you have to do
+/// it consistently. For example, if you wish to get [`RoomId`], [`MemberId`]
+/// and [`Endpoint`] ID from [`LocalUri`] in [`ToEndpoint`] state you should
+/// make this steps:
+///
+/// ```
+/// # use crate::api::control::local_uri::{LocalUri, ToEndpoint};
+/// # use crate::api::control::{RoomId, MemberId, EndpointId};
+/// #
+/// let orig_room_id = RoomId("room".to_string());

+///     orig_room_id.clone(),
+///     orig_member_id.clone(),
+///     orig_endpoint_id.clone()
+/// );
+/// let local_uri_clone = local_uri.clone();
+///
+/// // We can get reference to room_id from this LocalUri
+/// // without taking ownership:
+/// assert_eq!(local_uri.room_id(), &orig_room_id);
+///
+/// // If you want to take all IDs ownership, you should do this steps:
+/// let (endpoint_id, member_uri) = local_uri.take_endpoint_id();
+/// assert_eq!(endpoint_id, orig_endpoint_id);
+///
+/// let (member_id, room_uri) = member_uri.take_member_id();
+/// assert_eq!(member_id, orig_member_id);
+///
+/// let room_id = room_uri.take_room_id();
+/// assert_eq!(room_id, orig_room_id);
+///
+/// // Or simply
+/// let (room_id, member_id, endpoint_id) = local_uri_clone.take_all();
+/// ```
