Version 4.0 of WordPress, named “Benny” in honor of jazz clarinetist and bandleaderBenny Goodman, is available for download or update in your WordPress dashboard. While 4.0 is just another number for us after 3.9 and before 4.1, we feel we’ve put a little extra polish into it. This release brings you a smoother writing and management experience we think you’ll enjoy. Introducing WordPress 4.0 “Benny”

Manage your media with style
Explore your uploads in a beautiful, endless grid. A new details preview makes viewing and editing any amount of media in sequence a snap.
Working with embeds has never been easier
Paste in a YouTube URL on a new line, and watch it magically become an embedded video. Now try it with a tweet. Oh yeah — embedding has become a visual experience. The editor shows a true preview of your embedded content, saving you time and giving you confidence.
We’ve expanded the services supported by default, too — you can embed videos from CollegeHumor, playlists from YouTube, and talks from TED. Check out all of the embeds that WordPress supports.
Focus on your content
Writing and editing is smoother and more immersive with an editor that expands to fit your content as you write, and keeps the formatting tools available at all times.
Finding the right plugin

There are more than 30,000 free and open source plugins in the WordPress plugin directory. WordPress 4.0 makes it easier to find the right one for your needs, with new metrics, improved search, and a more visual browsing experience.
The Ensemble
This release was led by Helen Hou-Sandí, with the help of these fine individuals.
