2.31 [KK 2008-10-30] 
- Changes related to XML-style configuration file support. A
  new-style xrctl is in provided and during "make install" put in
  BINDIR (normally: /usr/sbin). See test/sampleconf.xml for an example
  of a configuration file.
- Added webinterface URI's to control DOS-protection related settings.
- Added DOS-protection variables to XML-output of the web interface.
- Server-wide maxconnection tag output moved into dosprotection block.
- Added display of such variables to the style sheet that renders the
  XML in a browser.
- Added option close-sockets-fast to XML output and to website URI
  controls.
- Added allow-from and deny-from lists to XML output and to website
  URI controls.
- Added the primary distribution site to the top-level Makefile as
  macro. This now shows up in "xr -V". The version ID and site also
  show up at the bottom of the web interface screen.
- Target "uninstall" added to the top-level Makefile.
- Bugfix in Netbuffer::netwrite(). When the remote connection would be
  hung up, XR would be blissfully unaware. SIGPIPE signals are now ignored.
- Implemented flag -g / --backend-check. Alternatives:
  connect:ip:port, get:ip:port[/uri], external:program.
- Added back end check type to the web interface reports, created
  control at web interface for /backend/NR/backendcheck/VALUE to
  change it. Added to XML configuration parsing.
- Docs updated, ofc.
- Status of balancer shown in web interface. Minor bugfix in xrctl.
- Added flags -E/-e (hard/soft-maxconn-excess, to call an external
  program). Also added to web interface with controls and updated docs.
- Added mutex locks around cerr output catch-blocks of exceptions.
- Added more checks for memory allocation faults.
- Implemented DNS caching of back end host names (flag -F,
  --dns-cache-timeout). Also implemented in web interface output and
  controls.
- Implemented adding and/or deleting back ends from the user
  interface, including scripting URI's.
- Implemented generation of a new configuration using "xrctl
  generateconfig".
