Following the first seed of iOS 10.1, Apple has now also seeded the first beta of watchOS 3.1 and tvOS 10.0.1 to developers. This comes only one week after launching the final version to the public. Right now we are unsure about what is new with both of these versions. As a .x update to watchOS, it seems like there would be some larger changes, but we haven’t noticed anything new on either of these versions. It’s likely just bug fixes and performance improvements.
To get the latest betas, developers can download the profile via the developer center to install watchOS 3.1. For tvOS 10.0.1, developers can download the firmware file and install it manually from iTunes.
