Version 4.0 of WordPress, named “Benny” in honor of jazz clarinetist and bandleader Benny Goodman.

This release includes hundreds of refinements and a few brand new features, culminating in a more polished media and editing experience. You will also find some awesome new tools for developers.

Here are some of the new features of 4.0

  • Explore your uploads in a beautiful, endless grid. A new details preview makes viewing and editing any amount of media in sequence a snap.
  • 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.
  • 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.
  • WordPress 4.0 makes it easier to find the right plugin for your needs, with new metrics, improved search, and a more visual browsing experience.
