-- [#200](https://github.com/zendframework/zend-expressive/pull/200) adds a new
-  interface, `Zend\Expressive\Router\RouteResultObserverInterface` (since moved
-  to the zend-expressive-router package). `Zend\Expressive\Application` now
-  also defines two methods, `attachRouteResultObserver()` and
-  `detachRouteResultObserver()`, which accept instances of the interface. During
-  `routeMiddleware()`, all observers are updated immediately following the call
-  to `RouterInterface::match()` with the `RouteResult` instance. This feature
-  enables the ability to notify objects of the calculated `RouteResult` without
-  needing to inject middleware into the system.
