“Reinhardt”, the WordPress 3.1 release is now available as a major core update for self-hosted WP blogs/CMS websites. The name is in honour of jazz guitarist Django Reinhardt.
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.

The first visual change you may note is the ‘link’ window, that pops up when applying a hyper-link to text. The new feature is an easier method of backlinking to existing media or posts.
As with all release updates, ensure you backup your database first to prevent content loss in the event of a problem, and ensure you also update any plugins as many will have newer versions compatible with version 3.1.
You can download WordPress 3.1, or use the Update option directly within the WP administration panel
