WordPress 2.7 Beta 2
I am currently using the beta version of WordPress 2.7 for RvF. Two of the most noticeable differences between 2.7 and 2.5 are the navigation scheme in the backend and the post writing are itself. The navigation took a little getting used to at first, but it has certainly grown on me. I love the vast amount of space given to you by default to write your posts in. Pretty much everything is customizable as far as the layout goes, which is quite handy. So far, no conflicts with the theme or plugins…yet.
