Debian changelog:

 nmap (4.53-1) unstable; urgency=low

   [LaMont Jones]
   * Package New upstream release.
   * Cherry pick post-4.53 patches from [fyodor]. Closes: #459884
     - remove instances of .nse to prevent the docbook man page translation
       from wrongly including that string at the beginning of lines, which causes
       errors because nroff confuses it with the .ns nroff no-space mode command
     - regenerate man page -- remove instances of .nse to prevent the
       docbook man page translation from wrongly including that string at the
       beginning of lines, which causes errors because nroff confuses it with
       the .ns nroff no-space mode command

   [stoiko]

   * if nse's connect is issued on an open socket, close the old
     connection before
   * move the check, wheter a socket is open, before connecting it again to
     l_nsock_queued() - otherwise there are problems with the returned values..

   [fyodor]

   * sorting change, I think
   * remove a duplicate for rpc number 536870916, userd or vtsk. I kept vksd
     though without much research. I'm open to comments from people who think
     we should keep userd instead.
   * Added rpcinfo.nse script, which contacts a listening RPC portmapper

   * applied an nginx http proxy signature patch from Sven Klemm

   [kris]

   * recommitting my r6499: "fix robots.nse output: remove robots.txt
     comments on disallowed entry lines"
   * Adding my strftime()-like conversion extensions to the logging functions
     (-oA, -oX, etc). This contains a CHANGELOG entry and refguide changes
     which (hopefully) sum it up pretty well.
   * okay, a change to r6530: the current %R and %T are being removed as
     colons are invalid chracters in Windows and Mac OS X filenames (thanks to
     jah for pointing out the problem on Windows). What was %r and %t are now
     the new %R and %T. All this means is that %r and %t are gone, and %R/%T
     are the same as with strftime() but without colons
   * adding CHANGELOG entry for r6529 (robots.nse output fix)
   * Add CHANGELOG entry for r6558: "Fix Zenmap crash when selecting Help from
     the Compare Results window. Path wasn't imported"
   * Adding new MySQLinfo NSE script for printing MySQL server information
   * Upgrading libpcre from version 7.2 to 7.4. Tested on Linux and Windows
   * Fixing build problem on Mac OS X; my mistake (typo)
   * adding nmap.fetchfile() function so scripts can find the nmap-* data files
   * updating rpcinfo.nse to use nmap.fetchfile() instead of having the huge
     RPC table
   * o Fixed multiple NSE scripts that weren't always properly closing their

   [ejlbell]

   * Traceroute bugfix for when the first hop of the first host in a
     tracegroup (reference trace) times out. The previous patch did not
     completely solve the issue due to an erronous check on the ttl, now we
     use a dedicated boolean flag. Thanks to Sebastián García for the bug
     report and testing.
