Apple purchased_Burstly last summer, and got the TestFlight beta-testing tool with it. Now it’s starting to add new features to the tool. Starting today, developers can organize their testers into separate groups to easily A/B test changes among them._Developers can choose to quickly send separate builds, provide different_instructions, or apply actions to several testers at once with the new update. Testflight announced it would be closing its old TestFllightApp.com website on February 26th; developers should set up their apps for iTunes Connect if they still want to use the service.
