The first thing you’ll notice about WordPress 2.7 is its new interface. Nearly every task you do on your blog will take fewer clicks and be faster in 2.7. The new dashboard can let you arrange with drag and drop to put the things most important to you on top, QuickPress, comment threading, paging, and the ability to reply to comments from your dashboard, the ability to install any plugin directly from WordPress.org with a single click, and sticky posts.

Digging in further you might notice that every screen is customizable. Let’s say you never care about author on your post listings — just click “Screen Options” and uncheck it and it’s instantly gone from the page. The same for any module on the dashboard or write screen.

If your screen is narrow and the menu is taking up too much horizontal room, click the arrow to minimize it to be icon-only, and then go to the write page and drag and drop everything from the right column into the main one, so your posting area is full-screen.

Last, but certainly not least, this may be the last time you ever have to manually upgrade WordPress again. Now WordPress includes a built-in upgrade that will automatically notify you of new releases, and when you’re ready it will download them, install them, and upgrade your blog with a single click.
