* Instead of printing all disallowed entries it now only prints the
first 20. In verbose and debug modes it prints more entries, the exact
number depends on the debug and vebose level
* Prints out the number of disallowed entries
* Prints a message if a robot.txt file exists but has not entries.
* More resilient parsing and duplicate removal code
* Extended the line length to 50 characters so less vertical space used
so they don't get mixed in with the files in /usr/share/{icons,pixmaps}.

o Modification to handle the problem where if a user modifies the
command entry field, Zenmap does not necessarily execute this command
and instead it will follow what the Target/Entry fields specify
instead. This avoids a bug where if you edited a command, then selected
a different target, the edited command line would be replaced with one
from the currently selected profile. [Jurand Nogiec]
to transfer. I've only been able to examine the behavior through Wireshark
since I don't have a nameserver that transfers other domains (I always get
"Not Authoritative"). It seems to work fine, though
doAnyOutstandingProbes performance improvements. Here is the log message from
r7914 in nmap-fixed-rate.
Keep a cache of the most recently processed probe for each host in
doAnyOutstandingRetransmits. This greatly reduces the amount of CPU used by
that function when the lists of outstanding probes grow long, such as when a
high scan rate is specified with --min-rate.
This is not most efficient possible way this could be done, but it is a pretty
big win, and it's very non-invasive. The changes are limited entirely to
doAnyOutstandingRetransmits, with no new global state in ultra_scan.

Note that 50000 packets per second is way excessive. I really only get about
6000 in practice. But the point is there is no huge CPU penalty for giving an
excessive rate.
of "*.*.*.*" from working. Support for the CIDR /0 is now also
available. [Kris]
A sendto() or connect() to IPv4 addresses with a first octet of 0
(excluding 0.0.0.0 on some OS's) returns EINVAL. These addresses
are reserved for "self-identification" and should never go over the
wire (and at least on Linux a connect() to 0.0.0.0 gets redirected
to 127.0.0.1). I'm talking with Fyodor on whether or not to skip
*all* of these addresses.
o Our WinPcap installer now starts the NPF driver running as a
service immediately upon installation and after restarts. You can
disable this with new checkboxes. This behavior is important for
Vista and Windows Server 2008 machines when User Account
Control (UAC) is enabled. [Rob Nicholls]
o Nmap and Nmap-Winpcap silent installation now works. Nmap can
be silently installed with the /S option to the installer.
If you install Nmap from the zip file, you can install just
Winpcap silently with the /S option to that
installer. [Rob Nicholls]
o Our WinPcap installer is now included with the Nmap Win32 zip
file. [Fyodor]
o Numerous miscellaneous improvements were made to our Win32
installer, such as using the "Modern" NSIS UI for WinPcap,
improving the option description labels, and showing a finish
page in all cases. [Rob Nicholls]
Now does most of it's work through Lua:
From Nmap-dev: "Many of the changes consist of changing how Nmap interfaces
with Lua that were sometimes awkward or inflexible. Most of the functions
have been made to be callable directly by Lua which offers many technical
advantages: stack management is alleviated, errors are handled cleanly and
are more descriptive, and there is increased reusability."
Additionally:
-- Moved all lua_State * symbols from "l" to "L". This is to maintain
consistency with other Lua libraries (convention) and to make our macros portable.
-- Moved file system manipulation over to nse_fs.cc (from nse_init.cc)
