+Changes With Apache Tuscany SCA 1.0 (incubating) September 2007 
+===============================================================
+
+- Tuscany Java SCA now implements V1.0 of the core SCA 
+  specifications
+        SCA Assembly Model V1.0
+        SCA Java Common Annotations and APIs V1.0
+        SCA Java Component Implementation V1.0
+        SCA Web Services Binding V1.0
+  Including callbacks, conversations and callable references
+  
+
+- Support for ws-security configurable in the web services binding
+  thro Tuscany SCA policy intents and policysets using the policy framework 
+  introduced in the last release.  
+  
+  Note : This release supports specifications of policies around axis2
+         config params - see helloworld-ws-service-secure sample.  The policy
+         intents that have been tested are authentication, integrity and 
+         confidentiality.  
+         There is no sample or test that exercises confidentiality since there
+         are some unresolved licensing issue around bouncycastle libraries.  
+         However, users who are not encumbered by the bouncycastle license 
+         restrictions can try the 'confidentiality' intent. See FAQ - 
+         http://incubator.apache.org/tuscany/tuscany-sca-java-faq.html
+                
+         This release does not include support for WS-Policy
+         attachments in Tuscany Policysets for ws-security.
+         
+  
+- An XQuery component implementation type 
+        implementation-xquery
+        
+
+- A Databinding for converting data to and from nodes for XQuery 
+  processing
+        databinding-saxon
+        
+
+- OSGI support has been extended to allow Tuscany contributions 
+  packaged as OSGI bundles hence taking advantage of OSGI's bundle
+  loading an dependency management capabilities 
+  
+
+- A BPEL component implementation type experimental implementation
+based on SCA BPEL Client and Implementation V1.0. At the moment only
+supports BPEL process as services.
+	implementation-bpel
+
+
+- The distributed runtime implementation has been separated out 
+  into 
+        *) domain
+        *) node
+  It is now wrapped by a SCADomain interface as is the standalone 
+  runtime.
+  
+  Note: This release does not include support for WebApp host deployment 
+        for a distributed SCA Domain 
+  
+
+
+- The web service binding will now generate WSDL automatically
+  based on the service interface if no WSDL is provided
+  
+
+- A new "store" sample and associated document show how a 
+  simple store front application can be constructed 
+        samples/store
+        
+- The following features of this release are still experimental:
+     - BPEL implementation type, integrating with Apache ODE
+     - OSGI implementation type, integrating with Apache Felix
+     - XQuery implementation type
+
+ 
+
+Changes With Apache Tuscany SCA 0.99 (incubating) August 2007 
+=============================================================
+
+The following are the significant additions to release 0.99 
+over and above all of what was offered in release 0.91.
+
+- A version of the default sca binding that works between
+  components runing in separate Java virtual machines
+       binding-sca-axis
+
+- A simple node implementation and a service discovery 
+  function for running sca applications distributed 
+  across more than one node
+       distributed
+       distributed-impl 
+
+- integration with OSGi runtimes is now supported with
+  a new implementation-osgi component type
+
+- PUB/SUB interactions are now supported by using new 
+  notification binding and implementation types, and
+  samples demonstrating the feature.
+
+- The Tuscany runtime now has a policy framework supporting
+  the SCA policy specification
+
+- the endpoint URIs used by SCA bindings has been rationalized 
+  and now follows the SCA Assembly specification
+
+- binding-ajax has been renamed to binding-dwr
+
