Twitterrific 5.6 has arrived on the App Store, adding some important new features, fixes, and improvements, the most notable of which is timeline streaming. Timeline streaming continuously updates your Twitter timeline while on Wi-Fi, and is enabled by going Twitterrific's settings, and selecting "Stream Timelines on WiFi".
There have also been improvements to list management and direct messages. You can now create and delete lists, add and remove users from lists, and edit list details and privacy settings. Twitterrific 5.6 also has support for viewing images in direct messages. You can't send images directly from Twitterrific, as Twitter has not made that feature accessable to developers at this time. You can also copy discussions from the share menu.
Smaller enhancements have been made as well. Links to Twitter custom timelines now open in Twitterrific's in-app browser. There have also been performance enhancements, including changes to prevent slow-downs over time.
You can download Twitterrific 5.6 from the App Store now.
