iOS 9.3.4 is "an important security update" that fixes a single issue which may allow applications to "execute arbitrary code with kernel privileges." What's most interesting is that Apple has credited Team Pangu, a prominent developer in the jailbreaking community, with uncovering the bug.
This update is clearly a response to the jailbreak released for iOS 9.3.3 by Team Pangu.
