 !!Incompatible Changes and Possible Transition Issues
 
   - Data::ODBC: UTF-16 Unicode is now directly mapped and recognized as type by ODBC.
     This may cause behavior different from previosu versions, especially with Any and 
 	Dynamic::Var bindings.
+	In this release, UTF-16 binding is only available for ODBC back end; although other 
+	back ends will compile with UTF-16 strings bound, such binding will throw 
+	NotImplementedException at runtime.
