Apple has released watchOS 4.1 and tvOS 11.1 beta 3 to registered developers.
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.
Last week, 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.
