Twitter has just updated its iPhone app. According to the official Twitter blog, the update comes with totally new redesigned user profile which focus on user biography, tweets, and photos, making it easier to get a glimpse into the people we care about on Twitter.
Along with the redesigned user profile, Twitter is also updating its app to take advantage of iOS 8. If your iPhone is running iOS 8, you can now interact directly with push notification from Twitter, meaning you can retweet, favorite, follow and more directly from the iOS 8 notifications.
Since the new redesigned user profile is rolling out, it may not be available in your country. I have updated the app and notice there is no changes at the moment.
