I just updated to WordPress version 2.8.4. The process wasn’t as simple as I had hoped. I had to backup a bunch of files and directories that I wanted to keep, unzip the new version, overwrite my WordPress installation directory with files from the new version, then copy the backed-up files back into the installation directory. After that, WordPress ran a database update script. Took me… 30 min. or so. At least everything seems to be working still.
Please let me know if anything on this site looks or behaves strangely.
