+	  <p>Fixed issue with handling of user provided occupant-id in
+	  messages and presences sent to muc room. Server was
+	  replacing just first instance of occupant-id with its own
+	  version, leaving other ones untouched. That would mean that
+	  depending on order in which clients send occupant-id, they
+	  could see value provided by sender, and that could be used
+	  to spoof as different sender.</p>
