@@ -27,6 +27,10 @@ o Nmap now has a public Subversion (SVN) source code repository. See
and then the updated usage instructions at
http://seclists.org/nmap-dev/2006/q4/0281.html .
o Fixed a major accuracy bug in gen1 OS detection (some debugging code
was accidentally left in). Thanks to Richard van den Berg for finding
the problem.
o Changed the IP protocol scan so that it sends proper IGMP headers when
scanning that protocol. This makes it much more likely that the host
will respond, proving that it's "open". [Kris]
