- Patch #1482 by djun: we're moving the DocBook output to a contributed module.  It's not a core feature.

  TODO:
  + The contact.module was broken; a new patch for contact.module is needed.
  + Documentation is needed.
  + The most important modules need to be updated ASAP.

- Patch #29910 by m3avrck, nsk, Thomas et al: added a mysqli database backend for use with PHP5 and MySQL 4.1 and above.

  NOTE: I don't have MySQL 4.1 setup at the moment so I could _not_ test this patch.  Luckily, various people reported that it works.

  to OPML export functionality, better code comments, better help texts, etc.

- Patch #24135 by Moshe: made it possible to ban visitors based on hostname/IP.  Banning visitors can either be done from the 'access control' pages, or directly from the statistics pages.  This feature is very convenient to block badly behaving crawlers.
