Today Apple has seeded iOS 10.2.1 publicly after 4 Betas. The update literally is only made out of BUG fixes and security enhancements, so there are no new features we should talk about, but there are some good news about it. In the security contents we can see that one of the WebKit exploits were sent to Apple by Pangu Team which means they are still active on iOS Security Research (unfortunately we have no idea if on Jailbreak too).
Unfortunately, the good news end there. Yesterday, following to his decision to join Apple Bug Bounty, Luca Todesco posted a tweet in which he said he will stop making any public Jailbreaks after he finishes the 10.2 "thing" because the Jailbreak Community's "idiocy" is too much for him to handle. We all know what that means. With Pangu not saying anything, Taig being inactive for over 1 year and a half now, most likely, Yalu will be the last Jailbreak in a very long time, so make sure you don't miss it.
Now, we do know that internet is a harsh environment, but I personally think Todesco gets pissed off too easy and takes everything personally. People are irritating when they ask 200 times a day when a Jailbreak will be out, but that doesn't mean one should stop doing something because others are curious / inpatient. Anyways, at the end of the day, we must understand that he does this in his free time and he is burning some serious hypervisor exploit. Anyways, don't update to 10.2.1 and if you are on 10.1.1 don't update to 10.2!
