+### Non Backward Compatible Changes
+
+- The default subscreen of webroot.xml has been changed from /apps to /vapps making the Vue based hybrid client/server rendering 
+  mode the default; most screens will work fine in it with no changes, but sometimes small tweaks are needed to make sure navigation
+  forms vs data submit forms are handled properly
