 - [#482](https://github.com/zendframework/zend-expressive/pull/482) fixes the
   `Application::$defaultDelegate` dockblock Type.
+- [#489](https://github.com/zendframework/zend-expressive/pull/489) fixes an
+  edge case in the `WhoopsErrorHandler` whereby it would emit an error if
+  `$_SERVER['SCRIPT_NAME']` did not exist. It now checks for that value before
+  attempting to use it.
