Apple today seeded the second iOS 9.1 beta to public beta testers



From MacRumors:

Public beta testers who already have iOS 9.1 installed can get the second beta as an over-the-air update, and those interested in getting early release software from Apple can sign up to participate in Apple's Beta Software Program. iOS 9.1 is an update mainly designed for the iPad Pro, adding support for accessories like the Smart Keyboard and the Apple Pencil, both of which require deep integration with iOS 9. It will also include support for the new Apple TV.
