+- [#156](https://github.com/zendframework/zend-inputfilter/pull/156) fixes an
+  issue introduced in 2.7.5 whereby the filter and validator chains composed in
+  inputs pulled from the `InputFilterPluginManager` were not receiving the
+  default filter and validator plugin manager instances. A solution was created
+  that preserves the original behavior as well as the bugfix that created the
+  regression.
