Changelog (entries related to the command line tools)

Nmap 6.47 [2014-08-20]

o Integrated all of your IPv4 OS fingerprint submissions since June 2013
  (2700+ of them). Added 366 fingerprints, bringing the new total to 4485.
  Additions include Linux 3.10 - 3.14, iOS 7, OpenBSD 5.4 - 5.5, FreeBSD 9.2,
  OS X 10.9, Android 4.3, and more. Many existing fingerprints were improved.
  Highlights: http://seclists.org/nmap-dev/2014/q3/325 [Daniel Miller]

o Removed the External Entity Declaration from the DOCTYPE in Nmap's XML. This
  was added in 6.45, and resulted in trouble for Nmap XML parsers without
  network access, as well as increased traffic to Nmap's servers. The doctype
  is now:
  <!DOCTYPE nmaprun>

o [Ncat] Fixed SOCKS5 username/password authentication. The password length was
  being written in the wrong place, so authentication could not succeed.
  Reported with patch by Pierluigi Vittori.

o Avoid formatting NULL as "%s" when running nmap --iflist. GNU libc converts
  this to the string "(null)", but it caused segfault on Solaris. [Daniel Miller]

o Handle ICMP admin-prohibited messages when doing service version detection.
  Crash reported by Nathan Stocks was: Unexpected error in NSE_TYPE_READ
  callback.  Error code: 101 (Network is unreachable) [David Fifield]

o [NSE] Fix a bug causing http.head to not honor redirects. [Patrik Karlsson]
