+## Disable multiple route rendering
+
+By default the router will try to execute all routes that matches a given url. To stop the router from executing any further routes any method can return a value.
+
+This behavior can be easily disabled by setting `SimpleRouter::enableMultiRouteRendering(false)` in your `routes.php` file. This is the same behavior as version 3 and below.
