I knew this would happen. WordPress has released a 2.6 version of their engine. I usually keep the software I use up-to-date. My original plan was to load 2.5.1 and then stay put. There are some features in the new version I would like to use (Theme Previews, Press This, some of the minor things) so I guess my plan didn’t get too far.
