What's New in Version 2.4
This release introduces Topics. A Topic is a way to let you quickly Tweet a group of related Tweets without having to manually reply to yourself and/or manually add the same hashtags over and over again. They are really great for rapid fire live Tweeting events.
You can access Topics by clicking the gear menu in the New Tweet screen. They are also stored in and require iCloud, so you can start a topic on your iPhone and easily continue it on your iPad and Mac.
