 ### Fixed
 
-- Nothing.
+- [#24](https://github.com/zendframework/zend-form/pull/24) ensures that when
+  `Zend\Form\Form::getInputFilter()` when lazy-creates an `InputFilter`
+  instance, it is populated with the `InputFilterFactory` present in its own
+  `FormFactory`. This ensures that any custom inputs, input filters, validators,
+  or filters are available to the new instance.
