The new changes allow users to customize profile pages with header photos that will be visable on Twitter.com, iPad, iPhone and Android. Profile header photos will also appear across mobile and desktop.
The best feature change is the background image enhancements which allows Twitter users to control the elements within the background image of the profile and display the most recent six images you shared via Twitter.
