WordPress has released version 3.3. Dubbed “Sonny” after jazz saxophonist Sonny Stitt, WordPress 3.3 packs in a number of worthwhile upgrades, including a new responsive design that adapts the WordPress admin to smaller screens.

To get the latest version head over to the WordPress downloads page. If you’re already using WordPress you can update from the WordPress dashboard (naturally we suggest backing up your files and database before you upgrade).

Among the changes that make WordPress 3.3 well worth the upgrade is the new responsive admin design. While there are mobile apps from managing your WordPress site on the go, the actual web admin has never adapted to small screens. That changes with WordPress 3.3 and its new responsive admin page, which reflows content to fit the screen you’re using.
