Moving closer to a public release, Apple has seeded tvOS 11.1 and watchOS 4.1 beta 4 to registered developers.
The Radio app is new to watchOS 4.1
Apple added two major new features in watchOS 4.1. Along with the ability to stream Apple Music over an LTE connection, a new Radio app has been added into the mix. You can take a look at our complete overview of both here.
Earlier this month, Apple released watchOS 4.0.1 to the public only for Series 3 models that fixed an issue with LTE and Wi-Fi connectivity.
There are no new user-facing features in tvOS 11.1.
Both software versions, along with iOS 11.1, should officially arrive to the public sometime early next month.
