 ## New Features
-
+- **Add sign-in request for authentication token retrieval**
+  A new mechanism of authentication tokens has been introduced to replace the old way of sending usernames and passwords through the network with every request.
+  
+  Instead, all user credentials (currently, it's usernames and passwords) are sent only:
+  * as a part of `connection_open` request for authentication and authorization, with a temporary token returned;
+  * as a part of `sign_in` request for sign ins within an established connection (to change the user or to get a new authentication token).
+  Then, all further requests are expected to be authenticated only by temporary, less sensitive tokens. 
+  
+  The approach is extensible to other credential types that can be introduced in the future.
