Testing:
This update was verified to work on iOS 11.1.1, 11.1.2, 11.2.1, 11.2.5, 11.3.1, 11.4, 11.4.1, 12.0, 12.1.1 and 12.1.2

Conclusion:

This update significantly improves the stability and the performance of the entire system, fixes issues in the jailbreak app makes it more user-friendly, stable and performant and adds support for switching from other iOS 12 jailbreaks without losing data.

As you might’ve noticed, this update has a strong focus on performance and stability. That said, all unc0ver users are advised to upgrade to the latest version of the jailbreak at their earliest convenience to reap the benefits.

The unc0ver jailbreak supports devices running iOS 11.0-12.1.2, but it’s worth noting that A12(X)-based handsets are only partially supported at the time of this writing due to the lack of Cydia Substrate support for these devices. Pwn20wnd will soon implement Substitute for A12(X) device users to mitigate this handicap.

Those interested in using the latest version of unc0ver can download it from Pwn20wnd’s official GitHub page.
