WordPress 2.8 New Features
First and foremost, 2.8 is way faster to use. They’ve changed the way WordPress does style and scripting.http://southpole2009.com/
The core and plug in updaters in previous versions of WordPress have been such a success they decided to bring the same to themes. You can now browse the entire theme directory and install a theme with one click from the comfort of your WordPress dashboard.
If you make edits or tweaks to themes or plug ins from your dashboard, you’ll appreciate the new CodePress editor which gives syntax highlighting to the previously-plain editor. Also there is now contextual documentation for the functions in the file you’re editing linked right below the editor.
If you were ever frustrated with widgets before, this release should be your savior. they’ve completely redesigned the widgets interface (which they didn’t have time to in 2.7) to allow you to do things like edit widgets on the fly, have multiple copies of the same widget, drag and drop widgets between sidebars, and save inactive widgets so you don’t lose all your settings. Developers now have access to a much cleaner and robust API for creating widgets as well.
Finally you should explore the new Screen Options on every page. It’s the tab in the top right. Now, for example, if you have a wide monitor you could set up your dashboard to have four columns of widgets instead of the two it has by default. On other pages you can change how many items show per page.
