Apple released today the first public beta versions of its upcoming iOS 12.1 and tvOS 12.1 operating systems for iPhone, iPad, iPod Touch, and Apple TV users.
The iOS 12.1 public beta and tvOS 12.1 public beta releases come just two days after Apple seeded the first developer betas of iOS 12.1 and tvOS 12.1 to registered application developers through its Apple Developer portal, along with the first beta of the watchOS 5.1 operating system.
As expected, the iOS 12.1 and tvOS 12.1 public beta versions include the same changes found in the first iOS 12.1 and tvOS 12.1 developer betas, including support for group FaceTime with up to 32 people at once, and support for upcoming iPad Pro 2018 models discovered by 9to5mac.
