What’s new about the new you? The new web profile lets you use a larger profile photo, customize your header, show off your best Tweets and more. Here are main features:

Best Tweets: Tweets that have received more engagement will appear slightly larger, so your best content is easy to find.
Pinned Tweet: Pin one of your Tweets to the top of your page, so it’s easy for your followers to see what you’re all about.
Filtered Tweets: Now you can choose which timeline to view when checking out other profiles. Select from these options: Tweets, Tweets with photos/videos, or Tweets and replies.

Coming soon to everyone
This new profile setup is available today to a small group of users. If you’re new to Twitter, you’ll start in with the new profile. In the coming weeks, we will roll out the new features to everyone.Twitter Introduces New Profile Page Setup To Roll Out Soon [blog.twitter.com]
