-====== Upgrading apps using OSInet FSM ======
-===== 1.1 to 1.2 ======
-  * The new post-event action feature allows shorter automata by event chaining
-  * The new default "idle" event allows automatic progress in the absence of explicit events. For instance, whereas a FTP client using FSM 1.1 will typically send events to connect, get and disconnect in PHP, the same can be done to a large extend using just the transitions table with FSM 1.2 using this mechanism to fire events in succession.
-  * Because of this change, fsm::apply_event() now returns a fsm_result instead of directly returning the next state. Code needing to know the next state can:
-    * either use apply_simple_event, which is equivalent to the previous incarnation of apply_event
-    * use the fsm_state field from the value returned by fsm::apply_event
