Beta 2 for iOS 8 has been released through Apple's Dev Center or through on-device updating. There are a bunch of new features included in iOS 8, and developers rely on these betas to make sure their apps are good to go for when iOS 8 goes live for the general populace this fall. The first beta launched alongside the original announcement a few weeks ago.
Devs, are you seeing the new beta? Noticing anything new? Any non-devs willing to risk having wonky performance on their daily iPhone to enjoy the bleeding edge of iOS?
