Looks like there is a update for Tweetbot 3 in the App Store. It is version 3.1. Here is the change log if you would like to see whats in this update.

What’s New in Version 3.1

– Using a list as your timeline is back (hold down on “Timeline” title to reveal the menu)
– Right swipe to quick reply (short swipe and release for custom action)
– Resize text within the app (Settings > Display)
– Option to set square avatars and hide timeline badges (Settings > Display)
– Email conversations or share via Storify
– “Last tweet x minutes ago” is back in the profiles (under recent images)
– Removed “Retweeted by” string so there’s less chance of truncation
– Lots of bug fixes
