New Twitter rollout: complete! All users now have the same Twitter.com experience & can access our latest features.
New design
You will now find @mentions, retweets, searches, and lists just above your timeline – creating a single, streamlined view on the left of the screen. On the right, you can see the features you’re familiar with, including whom you recently followed and who recently followed you, favorites, and Trending Topics.
Discover related content
When you click a Tweet, the details pane shows additional information related to the author or subject. Depending on the Tweet’s content, you may see: @replies, other Tweets by that same user, a map of where a geotagged Tweet was sent from, and more.
Rollout timing
These changes will roll out as a preview over the next several weeks. During the preview, you'll be able to switch back and forth so you have time to grow accustomed to the way things work. Eventually, everyone will have the updated version of Twitter.com.
