I carefully went through all the instructions to upgrade my site to v 2.1.1, and everything looks the same. My home page metafile still says 2.0.5 and when I look at the bottom of my admin dashboard, it says 2.0.5. Has anything changed, or not? I certainly haven't found anything new. How do I know if I upgraded or not? All the directories and wordpress files on my host are new. I thought something would look different.
