1.    NEW FEATURES

      CR10012483
      org:opencrx:kernel:generic:Media extends org:opencrx:kernel:generic:UserDefined.

      CR20029290
      RestServlet_2 supports JSON and Swagger:
      * Support for application/json in addition to text/xml
      * Swagger-compliant API at object-level with XRI-suffix :api and :api-ui

      CR10012500
      REST supports CORS. Cross-origin resource sharing (CORS) is a mechanism that 
      allows many resources (e.g., fonts, JavaScript, etc.) on a web page to be 
      requested from another domain outside the domain from which the resource originated. 
      In particular, JavaScript's AJAX calls can use the XMLHttpRequest mechanism. 
      Such "cross-domain" requests would otherwise be forbidden by web browsers, per the 
      same-origin security policy. Default CORS config added to web.xml of REST servlet. 
      For more information see http://tomcat.apache.org/tomcat-7.0-doc/config/filter.html#CORS_Filter.
      
      CR10012503
      Parameter xri for WorkflowHandler. The xri parameter allows to execute a specific 
      asynchronous workflow "on demand". Example:
      http://localhost:8080/opencrx-core-CRX/WorkflowHandler/execute?provider=CRX&segment=Standard&xri=xri://...
      The workflow is executed only if it is not already complete.

2.    CHANGES

2.0.  CHANGED FEATURES
      
      CR10012547
      Refactoring SubscriptionHandlerServlet. Move subscription.matches() operation to API and therefore
      implementation to backend classes. This allows custom-specific implementations of 
      UserHome.subscriptionMatches(). 

      CR10011964
      Allow to define an asynchronous workflow as (Janino) script. This way segment-specific 
      business-logic can be added without build / deploy. Asynchronous workflows
      must implement the following methods:
      * public static void execute(WfProcessInstance) {}
      * public static boolean isAtomic() {}

      Below is an example script for an asynchronous workflow:

      // <pre>
      public static void execute(
        org.opencrx.kernel.home1.jmi1.WfProcessInstance wfProcessInstance
      ) throws org.openmdx.base.exception.ServiceException {
        java.util.logging.Logger logger = java.util.logging.Logger.getLogger("PrintConsole");
        logger.log(java.util.logging.Level.INFO, "executing workflow " + wfProcessInstance.getProcess().getName());
        logger.log(java.util.logging.Level.INFO, "target=" + wfProcessInstance.getTargetObject());
        logger.log(java.util.logging.Level.INFO, "wfProcessInstance=" + wfProcessInstance);
        java.util.Map params = org.opencrx.kernel.utils.WorkflowHelper.getWorkflowParameters(wfProcessInstance);
        logger.log(java.util.logging.Level.INFO, "params=" + params);
      }

      public static boolean isAtomic(
      ) throws org.openmdx.base.exception.ServiceException {
        return true;
      }
      // </pre>
      
      CR20025970
      Migration from dataprovider stack version 1 to version 2:
      * Refactoring of all layer plugins
      * Amend jdoconfig.xml
      * Amend dataprovider configurations Kernel.properties, Security.properties
      * Amend build.properties

2.1.  FIXED BUGS
      
      CR10012452
      Wizards: exception handling. Improved error handling for in-place wizards.
      The AbstractWizardController reports the exception to the log file and stores
      the exception message in the field errorMessasge in case the execution of
      a command raises an exception. The wizards display the error message instead
      of terminating abnormally.

2.2   REMOVED FEATURES
