WordPress 2.5 has been released with a major overhaul to the interface and a range of new features. The biggest change is in the appearance of the administration backend, which is described as being a “Cleaner, faster, less cluttered dashboard.” The WordPress dashboard is now widget friendly, and users can include items such as stats, offering similar functionality to MovableType. Other new features include multi-file uploading, one-click plugin upgrades, built-in galleries, salted passwords and cookie encryption, media library, code friendly WYSIWYG, concurrent post editing protection, full-screen writing, and improved search.
