title: Updating from Joomla 1.5.20 to most secure release
body: <p>I'm updating a Joomla page for a friend of mine - and the version currently online (when it's not being brought down by hackers) is 1.5.20. As far as I can see, there are <a href="http://joomlacode.org/gf/project/joomla/frs/?action=index" rel="nofollow">no update patches available</a> to bring this up to date. I'm aware that I can't update this to a 2.x or a 3.x version, but if I at least could bring this up to the newest version of the 1.5.x releases, that'd be good for security.</p>
  
  <p>So, what patch should I choose, and where can I find it?</p>
