Drupal gets an upgrade to 4.7.4 via the Bluehost Fantastico auto-installer.
The Wiki gets converted to MediaWiki simply because it is a lot easier on the eye. This software requires PHP5 and I was originally on a server running PHP4. However I read that Bluehost does also support PHP5. I just asked politely and got moved to a different server. No fuss. No questions. Technical support just did it. Quickly and efficiently.
Of course, neither package is currently used but that’s beside the point.
DreamHost upgraded to the recently released WordPress 2.0.5 almost immediately. I think I prefer Bluehost’s strategy of waiting a while for any creases to be ironed out before upgrading.
