Highlights of WordPress 3.9 updates

Welcome to WordPress 3.9

Thank you for updating! WordPress 3.9 has lots of refinements we think you’ll love.
Version 3.9

A smoother media editing experience

Improved visual editing

The updated visual editor has improved speed, accessibility, and mobile support. You can paste into the visual editor from your word processor without wasting time to clean up messy styling. (Yeah, we’re talking about you, Microsoft Word.)

Edit images easily

With quicker access to crop and rotation tools, it’s now much easier to edit your images while editing posts. You can also scale images directly in the editor to find just the right fit.

Drag and drop your images

Uploading your images is easier than ever. Just grab them from your desktop and drop them onto the editor.


Gallery previews

Galleries display a beautiful grid of images right in the editor, just like they do in your published post.

Do more with audio and video

Images have galleries; now we’ve added simple audio and video playlists, so you can showcase your music and clips.


Live widget and header previews

Add, edit, and rearrange your site’s widgets right in the theme customizer. No “save and surprise” — preview your changes live and only save them when you’re ready.

The improved header image tool also lets you upload, crop, and manage headers while customizing your theme.

Stunning new theme browser

Looking for a new theme should be easy and fun. Lose yourself in the boundless supply of free WordPress.org themes with the beautiful new theme browser.

Semantic Captions and Galleries

Inline Code Documentation

External Libraries

Updated libraries: TinyMCE 4, jQuery 1.11, Backbone 1.1, Underscore 1.6, Plupload 2, MediaElement 2.14, Masonry 3.

Improved Database Layer

Database connections are now more fault-resistant and have improved compatibility with PHP 5.5 and MySQL 5.6.

New Utility Functions

Identify a hook in progress withdoing_action() and doing_filter(), and manipulate custom image sizes withhas_image_size() andremove_image_size().

Plugins and themes registering custom image sizes can now register suggested cropping points. For example, prevent heads from being cropped out of photos with a top-center crop.
