   also now deleted properly on Vista. [Rob Nicholls]
@@ -12,6 +13,15 @@ o Added UPnP-info NSE script by Thomas Buchanan. It gathers
   many network devices such as routers, printers, and networked media
   players.
 
+o Fixed a --traceroute bug (assertion failure crash) which occured
+  when the first hop of the first host in a tracegroup (reference
