Welcome to WordPress 4.0
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.

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