WordPress 3.5.1

State-of-the-art semantic personal publishing platform with a focus on aesthetics, web standards, and usability.

WordPress is web software you can use to create a beautiful website or blog. We like to say that WordPress is both free and priceless at the same time.

The core software is built by hundreds of community volunteers, and when you’re ready for more there are thousands of plugins and themes available to transform your site into almost anything you can imagine. Over 25 million people have chosen WordPress to power the place on the web they call “home” — we’d love you to join the family.

This release features a lightning fast redesigned linking workflow which makes it easy to link to your existing posts and pages, an admin bar so you’re never more than a click away from your most-used dashboard pages, a streamlined writing interface that hides many of the seldom-used panels by default to create a simpler and less intimidating writing experience for new bloggers (visit Screen Options in the top right to get old panels back), and a refreshed blue admin scheme available for selection under your personal options.

There’s a bucket of candy for developers as well, including our new Post Formats support which makes it easy for themes to create portable tumblelogs with different styling for different types of posts, new CMS capabilities like archive pages for custom content types, a new Network Admin, an overhaul of the import and export system, and the ability to perform advanced taxonomy and custom fields queries.
