Well, a few hours of updating, uploading and customizing later, I have a freshly upgraded copy of WordPress 2.5 running Consolation Champs. I had to also update my current theme, Cutline, and then re-add all my customized header images, which also needed to be resized. So, these things never go as smoothly as advertised. A few familiar things are looking unfamiliar, but overall, it was fairly painless. Let me know if anything looks strange to you (other than the strange header images, which are strange all the time).
