As you may recall, a couple of days ago we reported on an upcoming jailbreak for the Apple TV 4 and tvOS 10, from macOS and iOS internals researcher Jonathan Levin. At that time the tool was undergoing some final beta testing, but as of today the wait is over, and the jailbreak has been made available to the public.
In addition to releasing the second major update to El Capitan and iOS 92 with Safari View Controller enhancements, Arabic Siri support and other improvements, Apple this morning also posted a matching software update for the fourth-generation Apple TV.
Marking the second software update since the new Apple TV's debut in October of this year, tvOS 9.1 (build 13U85) is a bug-fix update which includes a couple of fixes for the most pressing issues reported by users.
In addition to releasing iOS 9.2 beta 4 to developers and public beta testers, Apple on Wednesday also released a third beta of tvOS 9.1 to developers, its operating system for the fourth-generation Apple TV.
The tvOS 9.1 beta 3 update (build number: 13U5077a) is available over-the-air on the new Apple TV to developers who are on a prior tvOS beta, as well as a standalone download through Apple's portal for developers.
Apple has released its first post-release beta of tvOS to developers. tvOS 9.1 beta 1 is a 900MB download arrives with build number 13U5061d. Apple has released a change log alongside the tvOS beta, but it doesn't include any user-facing features that should impact day to day usage of a non-developer.
