 # Nmap Changelog ($Id$); -*-text-*-
 
+o [Ndiff] The Nmap banner (with the version number and date of the scan)
+  is not printed unless there were other differences. This makes Nidff
+  produce no output when there wre no differences other than the version
+  number and date. Dr. Jesus contributed an initial patch. [David]
+
 o [Zenmap] Fixed a bug in the option parser: -sN (null scan) was
   interpreted as -sn (no port scan). This was reported by
   shitaneddine. [David]
