(WID/WPS) Whats new in WID 6.2

• The Solution view is a new view that shows how our modules, mediation modules, and libraries relate each other. (Integration solutions)
• Included Generalized Flows (formerly called Cyclic Flows), Repeat Until loops, and Collaboration Scope.
• In previous releases, business object maps were only used in the assembly diagram. Now we can use a business object map as a step of our  business process.
• Support for Services Gateway pattern. 

Mediation Related Changes :

• The Mediation Flow editor has improved support for protocol specific headers, including CICS and IMS messages. 
• Mapping has been improved to support very large business objects. 
• Mediation flows and XSLT transformations can now be included in a business module, rather than needing their own module. Performance is improved by eliminating the hop between modules, improving efficiency.Multiple mediation components can now be placed into a single module. Since a mediation flow is treated like any other component now, there is no longer a need for a specialized mediation module. A mediation can be part of any module now.
• A new construct called a mediation subflow can be used to encapsulate reusable mediation logic.
