+Action Trigger Event Repeatability
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Action Trigger Event Definitions have a new field, "Event Repeatability
+Delay". This feature allows events to be repeated after the designated
+delay interval. An example of this is sending a notification email when a
+patron's library card expires. If the library extends the expiration date
+on that card, we then need a way to send another notification email when
+that same card expires again. Before, the Action Trigger processor only
+created a new event if the event definition for that target had never
+been run before. But now it allows repeating of the event after the delay
+interval, if present.
