+\item The IDLE integrated development environment has been updated

 \item The DOM implementation
 in \module{xml.dom.minidom} can now generate XML output in a
 particular encoding by providing an optional encoding argument to
 the \method{toxml()} and \method{toprettyxml()} methods of DOM nodes.
 
+\item The \module{xmlrpclib} module now supports an XML-RPC extension
+for handling nil data values such as Python's \code{None}.  Nil values
+are always supported on unmarshalling an XML-RPC response.  To
+generate requests containing \code{None}, you must supply a true value
