Twitter has released an update to its iOS app that adds new features and several improvements. The biggest new feature is the ability to view global trends. Previously a user could view local trends in the Discover tab, but now you can select global trend locations and view trending hashtags from locales across the world.
Twitter for iOS now also lets you invite friends to join Twitter from within the app. Previously this feature was only found on its web-based client. Also, retweets have been tweaked to include both the original author's Twitter handle and the handle of the person retweeting it. Finally, Twitter has improved the playback of Vine videos within the app.
