+<RN type="feature">New Throttle attribute for event handler methods - ensures last event is delivered after X seconds</RN>
+
+```csharp
+services.AddShinyMediator(x => x.AddThrottledEventHandlers());
+
+public class MyEventHandler : IEventHandler<MyEvent>
+{
+  [Throttle(1000)] // respresents milliseconds, so 1000 = 1 second
+  public Task Handle(MyEvent myEvent, EventContext context)
+  {
+    // this will ensure that if multiple MyEvent are published within 5 seconds, only the last one will be delivered after the 5 seconds is up
+    // if only one event is published, it will be delivered immediately
+    // if multiple events are published, the timer resets with each new event and only the last event is delivered after 5 seconds of no new events
