WordPress 2.7 ?Coltrane?
The first thing you?ll notice about 2.7 is its new interface. From the top down, [they?ve] listened to [our] feedback and thought deeply about the design and the result is a WordPress that?s just plain faster. Nearly every task you do on your blog will take fewer clicks and be faster in 2.7 than it did in a previous version. (Download it now, or read on for more.)
But before you do, here’s some valuable advice – deactivate the Lighter Menus plugin before upgrading (and keep it deactivated) If you don’t, you’ll run into the same problem I did which is not seeing your dashboard navigation and thus having to rely on your WordPress backend navigation memory (or compare it to your un-upgraded blog).
The problem is that the dashboard has a whole new interface which is (hopefully) cleaner and the elements can be dragged around (or minimized) for better placement. Of course, any major change will take getting used to, especially for veteran WP users but flexability is why you use WordPress in the first place, right?
