That does not seem to be the case as nobody knows what Pangu is up to anyway.
He ran into trouble with 10.1.1 and is half solving it, in the process he is half JBing 10.2.
Now everybody is scattered over different iOS versions, Saurik was already complaining about that and it is a hassle with Cydia.
Usually I am pretty mild especially concerning devs as they work hard and mostly for free, but this time it seems it is all messed up and getting worse.
Better for Luca to stop the development now and not release anything until a stable JB, I f I was him I would go solely for 10.2 and skip 10.1.1 altogether, better to focus all energy and time towards 1 single JB.
Hopefully the devs pull together to work something out in the background.
Luckily I stayed on 9.3.3 and have no drama....
Idk seems to me like he has exploits but he didn't want to burn them on 10.1.1 so by using those new exploits for the 10.2 jailbreak, he will be able to fix the 10.1.1. But that's all just speculation by me.
