iOS 10 jailbreak release date: Increased security and Apple's efforts hinder Pangu to perfect software?

Jailbreak fans are starting to worry about the status of the iOS 10 jailbreak from the Chinese jailbreak development team Pangu, who is yet to provide an update on the software.
Apple is moving fast, having just released the second updated version of the iOS 10, which was also equipped with the technology that kills any jailbreak installed on the iOS device that gets updated.
The Cupertino-based company is becoming more and more serious in combating and putting an end to jailbreaking and it appears that their efforts are working with Pangu still mum about their iOS 10 jailbreak.
The only time that the jailbreak development team talked about the software was when they announced it back in July at the Mobile Security Conference (MOSEC).
At that time, Pangu successfully jailbroke iOS 10 beta 1, which is likely rendered unusable now with all the updates that Apple has released since.
It is looking like Pangu is struggling to come out with a working iOS 10 jailbreak especially with Apple keen on putting it out of use in a new software update.
The silence from Pangu is also scaring users. Last year, the China-based group was also mum about their jailbreak projects as Apple continued updating the iOS 9.
The team came out with an iOS 9.1 jailbreak when the iOS 9.3 is already being rolled out. By that time, Apple no longer allowed anyone who updated their software to downgrade.
This is once again the same dilemma that Pangu is facing with the iOS 10 jailbreak, which is why it is now being reported that the tool will be here late or not at all.
In addition to that, the iOS 10 also features an improved security, according to exploit broker Zerodium, who, because of this, was forced to increase its bounty from $1 million to $1.5 million for anyone who successfully jailbreaks the iOS 10 remotely.
