 ### 1.1 Version check
 Client:
 ```

-	"version": string,
-	"sid": string

 }
 ```
-Only sends `sid` if client has an old sessionID.
 
 
 Server:
 ```

 }
 ```
 
-If `accept` is `true` the connection is valid. Else the connection will be terminated.
-`sid` can be set if accept is `true` and must be set if the `sid` of the client is invalid. So the server gives a new `sid` if the session is invalid. The server can as well use no `sid`. If the server forbids `sid`s but the client is offering one then the connection is to be immediately closed!
+If `accept` is `true` the connection is valid. Else the connection will be terminated after the server answered.
 
 ### 1.2 Login
 Client:
