On February 23, 2011, WordPress **Version 3.1** “Reinhardt”, named in honor of the
jazz guitarist [Django Reinhardt](http://en.wikipedia.org/wiki/Django_Reinhardt),
was released to the public. For more information on this enhancement and bug release,
read the [WordPress Blog](https://wordpress.org/news/2011/02/threeone/), and see
the [Changelog for 3.1](https://codex.wordpress.org/Changelog/3.1).

For **Version 3.1**, the database version (**db_version** in **wp_options**) changed
to 17056, and the [Trac](https://core.trac.wordpress.org/) revision was 17485.

## 󠀁[Highlights](https://wordpress.org/documentation/wordpress-version/version-3-1/?output_format=md#highlights)󠁿

 * **Internal Linking** – click a button for an internal link and it allows you 
   to search for a post or browse a list of existing content and select it for inclusion.
 * **Admin Bar** – contains various links to useful admin screens. By default, the
   admin bar is displayed when a user is logged in and visiting the site and is 
   not displayed in admin screens for single blog installs. For multisite installs,
   the admin bar is displayed both when visiting the site and in the admin screens.
 * **Streamlined Writing Interface** – new users of WordPress will find the write
   screen much less cluttered than before, as more of the options are hidden by 
   default. You can click on Screen Options in the top right to bring them back.
 * **Post Formats** – meta information that can be used by themes to customize presentation
   of a post. Read more in the article [Post Formats](https://codex.wordpress.org/Post_Formats).
 * **Network Admin** – move Super Admin menus and related pages out of the regular
   admin and into a new [Network Admin screen](https://codex.wordpress.org/Network_Admin).
 * **List-type Admin Screens** – sortable columns for list-type screens and better
   pagination.
 * **Exporter/Importer Overhaul** – many under the hood changes including adding
   author information, better handling for taxonomies and terms, and proper support
   for navigation menus.
 * **Custom Content Type Improvements** – allows developers to generate archive 
   pages, and have better menu and capability controls. Read more in the article
   [Post Types](https://codex.wordpress.org/Post_Types).
 * **Advanced Queries** – allows developers to query multiple taxonomies and custom
   fields.
 * **Refreshed Blue Admin Color Scheme** – puts the focus more squarely on your 
   content.
