 ====== Upgrading apps using OSInet FSM ======
+===== 1.3 to 1.4 =====
+  * No application changes are necessary, BUT :
+  * applications can now use external FSM descriptions in XML format. Building the FSM directly in code still works but it deprecated. It may go away at some later point. Constructors now typically look like just this:
+<php>
+  function __construct()
+    {
+    $this->load_fsm();
+    parent::__construct();
+    }
+</php>
+  * The XML file holding the FSM description is found by default if it is called <foo>.xml for class <foo>. Otherwise, use load_fsm($url);
+===== 1.2 to 1.3 ======
+  * No application changes are necessary.
+  * New features:
+    * enable/disable idle processing
+    * idle() shorthand method
+    * additional operation modes:
+      * fsm::EVENT_NORMAL works as previously
+      * fsm::EVENT_QUEUE queues events for later use
+      * fsm::EVENT_SINK discards events
+    * enable/disable post-event actions
 ===== 1.1 to 1.2 ======
