+Actions and guards that follow eventless transitions will now receive the event that triggered the transition instead of a "null" event (`{ type: '' }`), which no longer exists:
+
+```js
+// ...
+states: {
+  a: {
+    on: {
+      SOME_EVENT: 'b'
+    }
+  },
+  b: {
+    always: 'c'
+  },
+  c: {
+    entry: [(_, event) => {
+      // event.type is now "SOME_EVENT", not ""
+    }]
+  }
+}
+// ...
+```
