+- [#88](https://github.com/zendframework/zend-mvc/pull/88) addresses backwards
+  compatibility concerns raised by users due to the new deprecation notices
+  emitted by `ServiceLocatorAware` initializers; in particular, all
+  `AbstractController` implementations were raising a deprecation wen first
+  pulled from the `ControllerManager`.
+
+  At this time, notices are now only raised in the following conditions:
+
+  - When a non-controller, non-plugin manager, `ServiceLocatorAware` instance
+    is detected.
+  - When a plugin manager instance is detected that is `ServiceLocatorAware` and
+    does not have a composed service locator. In this situation, the deprecation
+    notice indicates that the factory for the plugin manager should be updated
+    to inject the service locator via the constructor.
+  - For controllers that do not extend `AbstractController` but do implement
+    `ServiceLocatorAware`.
+  - When calling `getServiceLocator()` from within an `AbstractController`
+    extension; this properly calls out the practice that should be avoided and
+    which requires updates to the controller.
