+CHANGELOG
+=========
+
+4.3.0
+-----
+
+ * The signature of the `EventDispatcherInterface::dispatch()` method should be updated to `dispatch($event, string $eventName = null)`, not doing so is deprecated
+ * deprecated the `Event` class, use `Symfony\Contracts\EventDispatcher\Event` instead
+
+4.1.0
+-----
+
+ * added support for invokable event listeners tagged with `kernel.event_listener` by default 
+ * The `TraceableEventDispatcher::getOrphanedEvents()` method has been added.
+ * The `TraceableEventDispatcherInterface` has been deprecated.
+
+4.0.0
+-----
+
+ * removed the `ContainerAwareEventDispatcher` class
+ * added the `reset()` method to the `TraceableEventDispatcherInterface`
+
+3.4.0
+-----
+
+  * Implementing `TraceableEventDispatcherInterface` without the `reset()` method has been deprecated.
+
+3.3.0
+-----
+
+  * The ContainerAwareEventDispatcher class has been deprecated. Use EventDispatcher with closure factories instead.
+
+3.0.0
+-----
+
+  * The method `getListenerPriority($eventName, $listener)` has been added to the
+    `EventDispatcherInterface`.
+  * The methods `Event::setDispatcher()`, `Event::getDispatcher()`, `Event::setName()`
+    and `Event::getName()` have been removed.
+    The event dispatcher and the event name are passed to the listener call.
+
+2.5.0
+-----
+
+ * added Debug\TraceableEventDispatcher (originally in HttpKernel)
+ * changed Debug\TraceableEventDispatcherInterface to extend EventDispatcherInterface
+ * added RegisterListenersPass (originally in HttpKernel)
+
+2.1.0
+-----
+
+ * added TraceableEventDispatcherInterface
+ * added ContainerAwareEventDispatcher
+ * added a reference to the EventDispatcher on the Event
+ * added a reference to the Event name on the event
+ * added fluid interface to the dispatch() method which now returns the Event
+   object
+ * added GenericEvent event class
+ * added the possibility for subscribers to subscribe several times for the
+   same event
+ * added ImmutableEventDispatcher

+them.
