Release Notes: Changes coming in WordPress 3.5 include a simplified welcome screen, a new color picker, and HiDPI graphics (AKA "retina") throughout the Dashboard. WP_Query can now return posts in a specific order with the post__in parameter. New Posts and Comments APIs are available. There's now support for protcocol-relative links when enqueuing scripts and styles. Updates have been applied to SimplePie, jQuery, jQuery UI, and TinyMCE, and newly-added Underscore and Backbone libraries. A revamped Media Library is still in development.
