If you happened to find this site any time yesterday afternoon, you probably caught me in the middle of upgrading to WordPress 2.1 Ella. So far, the differences are mostly small–there are a few plugins I wanted that only worked under 2.1, so I had to upgrade, but I was otherwise fine with 2.0.x. The post editor is probably the biggest difference, though it’s not all that different. The visual/code tab thing works well, autosave is nice, and spellcheck is always a good thing. If you find, as I did, that there are icons missing in the editor after upgrading, clear your browser cache and hopefully all will be resolved. Oh, and if you press Alt+V in IE or Alt+Shift+V in Firefox while in the editor, you get an additional bar of “advanced” buttons.
