As is their ways WordPress has released the latest version of the WordPress CMS and named it after a legendary musician saxophonist Sonny Stitt.
WordPress.org claims that “in this third major iteration we’ve added significant polish around the new user experience, navigation, uploading, and imports”
Below is a list of new features and updates lifted from the WordPress.org Website
Experienced users will appreciate the new drag-and-drop uploader, hover menus for the navigation, the new toolbar, improved co-editing support, and the new Tumblr importer. We’ve also been thinking a ton about what the WordPress experience is like for people completely new to the software. Version 3.3 has significant improvements there with pointer tips for new features included in each update, a friendly welcome message for first-time users, and revamped help tabs throughout the interface. Finally we’ve improved the dashboard experience on the iPad and other tablets with better touch support.
There is a ton of candy for developers as well. I’d recommend starting your exploration with the new editor API, new jQuery version, better ways to hook into the help screens, more performance post-slug-only permalinks, and of course the entire list of improvements on the Codex and in Trac.
