+Note that as of wxWidgets 2.9.0, wxVariantData no longer inherits from wxObject
+and wxVariant no longer uses the type-unsafe wxList class for list
+operations but the type-safe wxVariantList class. Also, wxVariantData now
+supports the Clone function for implementing the \helpref{wxVariant::Unshare}{wxvariantunshare} function.
+Clone is implemented automatically by IMPLEMENT\_VARIANT\_OBJECT.
+
+Since wxVariantData no longer derives from wxObject, any code that tests the type
+of the data using wxDynamicCast will require adjustment. You can use the macro
+wxDynamicCastVariantData with the same arguments as wxDynamicCast, to use C++ RTTI
+type information instead of wxWidgets RTTI.
