The team made the announcement on Twitter.
We will release jb for Apple TV4(9.0.x) next week which only has SSH access. It's mainly for security researchers and jailbreak developers.
It's been a very long time since the Apple TV has been jailbroken so this is a pretty exciting development for the jailbreak community. With the new, more powerful Apple TV 4, we could see some exciting stuff from developers.
Earlier today Pangu released a jailbreak for iOS 9.1. More information on that here.
