Release notes for a forthcoming update of the Twitter iOS app, v4.3, have leaked through iOS 6's redesigned App Store, according to 9to5Mac. The notes say, for instance, that content previews including images and video should be shown for tweets linking to unspecified "partner websites." Tweets about "selected events" will meanwhile be highlighted, with Twitter itself curating posts and images. In terms of notifications, people should be able to receive push alerts when a specific person has tweeted, and subtle Tweetbot-style notifications while in-app.
