-### Currently being worked
-
-- unit tests coverage
-- separation of HTTP protocol specification like URL path and HTTP verbs from the API of properties, actions and events and move their customization completely to the HTTP server 
-- serve multiple things with the same server (unfortunately due to a small oversight it is currently somewhat difficult for end user to serve multiple things with the same server, although its possible. This will be fixed.)
-- improving accuracy of Thing Descriptions 
-- cookie credentials for authentication - as a workaround until credentials are supported, use `allowed_clients` argument on HTTP server which restricts access based on remote IP supplied with the HTTP headers. This wont still help you in public networks or modified/non-standard HTTP clients.
