WordPress 3.3 is now available as a download as well as an update in existing installations’ administrative screen.

My first impressions: the user interface felt more responsive than before and has been tweaked for improved efficiency. From what I understand, this update delves below the dated interface, polishing some rust off the underlying platform to improve general performance, notably in processing permalinks and slugs.

Yeah WordPress has been powering a significant demographic of the blogging world for some time but the platform has really been improving nicely since the big 3.0 and version 3.3 is carrying this trend forward.
