+NEW Improvements in version 2.0.0
+---------------------------------
+
+This release tries to fix some major bugs and introduces backward incompatible changes. 
+ - The complex type list will contain now exactly same types used when doing an actual SOAP request
+ - Same for when listing the soap actions ( the return type and parameters ).
+ 
+Initially the way the complex types were shown on the page was not correct, because it was not reflecting 
+the actual way the SOAP action receives its arguments when doing an actual SOAP request to that controller
+
+The main issue was not handling correctly the classes that are inheriting from WashOut::Type. 
+
+This release tries to fix those issues.

 NEW Improvements in version 1.4.0
 ---------------------------------
 
 -	when displaying all services , the link to documentation is now using the new format **/soap_doc** for better readability
 -	Fixed an issue when generating documentation for a controller that didn't had the namespace set, the WSDL url and endpoint was missing from the generated source because of that. However if you don't set the namespace in controller the links to WSDL and endpoint would throw an error when trying to access them.
