-        
+      Spring Security 2.0.0 builds on Acegi Security's solid foundations, adding many new features:
+
+      * Simplified namespace-based configuration syntax. Old configurations
+       could require hundreds of lines of XML but our new convention over configuration 
+       approach ensures that many deployments will now require less than 10 lines.
+
+      * OpenID integration, which is the web's emerging single sign on
+      standard (supported by Google, IBM, Sun, Yahoo and others)
+
+      * Windows NTLM support, providing easy enterprise-wide single sign on
+      against Windows corporate networks
+
+      * Support for JSR 250 ("EJB 3") security annotations, delivering a
+      standards-based model for authorization metadata
+
+      * AspectJ pointcut expression language support, allowing developers to
+      apply cross-cutting security logic across their Spring managed objects
+
+      * Substantial improvements to the high-performance domain object
+      instance security ("ACL") capabilities
+
+      * Comprehensive support for RESTful web request authorization, which
+      works well with Spring 2.5's @MVC model for building RESTful systems
+
+      * Long-requested support for groups, hierarchical roles and a user
+      management API, which all combine to reduce development time and
+      significantly improve system administration
+
+      * An improved, database-backed "remember me" implementation
+
+      * Support for portlet authentication out-of-the-box
+
+      * Support for additional languages
+
+      * Numerous other general improvements, documentation and new samples
+
+      * New support for web state and flow transition authorization through
+      the Spring Web Flow 2.0 release
+
+      * New support for visualizing secured methods, plus configuration
+      auto-completion support in Spring IDE
+
+      * Enhanced WSS (formerly WS-Security) support through the Spring Web
+      Services 1.5 release
+
+      * Updated support for CAS single sign-on (CAS 3 is now supported).
