 ### Fixed
 
-- Nothing.
+- [#134](https://github.com/zendframework/zend-form/pull/134) fixes how the
+  `FormElementManager` handles invokable classes when the `autoAddInvokableClass`
+  flag is enabled. Previously, it used the built-in utilities from
+  zend-servicemanager, but now correctly uses its own `setInvokableClass()`
+  method, which forces usage of the `ElementFactory` for such classes, and thus
+  ensures the name and options are passed to the element constructor.
