ECSG with the help of TAs (Chuck Brugger and Jeff Murrell) has created a white paper highlighting the new features/differences in the MPA 2.0 platform.  While focused on MPA 2.0 the document also touches on differences in some of the old platforms.  This is a partner/customer facing document. The doc is also posted on the ECSG site at http://compass.mot-solutions.com/go/ecsg-home.
