+2.2 Migration Guide
+###################
+
+CakePHP 2.2 is a fully API compatible upgrade from 2.1.  This page outlines the
+changes and improvements made for 2.2.
+
+ExceptionRenderer
+==========
+
+The `CakeErrorController` used by `ExceptionRenderer` to render error pages now
+uses layout `error.ctp` instead of `default.ctp`. So create an `error.ctp` in
+your app's layouts folder. This prevents nested errors caused in some cases
+due to use of default layout error.
