+- [#627](https://github.com/zendframework/zend-expressive/pull/627) fixes an issue in the Whoops response generator; previously, if an error or
+  exception occurred in an `ErrorHandler` listener or prior to handling the pipeline,
+  Whoops would fail to intercept, resulting in an empty response with status 200. With
+  the patch, it properly intercepts and displays the errors.
