+- [#56](https://github.com/zendframework/zend-stdlib/pull/56) updates the
+  `AggregateHydrator` implementation to add overrides for the `hydrate()` and
+  `extract()` methods; this was done to ensure they trigger zend-stdlib-specific
+  event classes (vs the zend-hydrator base classes), in order to ensure
+  backwards compatibility.
