+- [#612](https://github.com/zendframework/zend-expressive/pull/612) updates the
+  `ApplicationConfigInjectionDelegator` delegator factory logic to cast the
+  `$config` value to an array before passing it to its
+  `injectPipelineFromConfig()` and `injectRoutesFromConfig()` methods, ensuring
+  it will work correctly with containers that store the `config` service as an
+  `ArrayObject` instead of an `array`.
