The Yalu jailbreak for iOS 10 is in the seventh beta currently and it supports most 64-bit devices including iPhone 6s, iPhone 6, iPhone 5s and more.
However, iPhone 7 and iPhone 7 Plus users are out of luck as the only jailbreakable firmware for these devices are iOS 10.1 and iOS 10.1.1. This means that if you own an iPhone 7 running iOS 10.2, you cannot jailbreak it with Yalu beta 7.
The good news is that the man behind the Yalu jailbreak, aka Luca Todesco, has confirmed that the jailbreak will be updated at some point to support iPhone 7, but it will not happen now.
To clear it up: Yalu1011 for iPhone 7 will be updated at some point. Just not a priority right now. Got stuff to do.

Luca hasn’t stated when the update will be released, but it’s good to hear that iPhone 7 and iPhone 7 Plus models will not be left in the dark. If you’re on iOS 10.2, I’d recommend that you stay put and avoid updating to the latest firmware, which is iOS 10.2.1.
Apple has already closed the signing window for iOS 10.2 and this prevents users from downgrading or upgrading to that firmware manually using iTunes. This is why if you own an iPhone 7 that is on iOS 10.2, then it’s best that you remain on that version and avoid updating.
