unc0ver, the controversial jailbreak for iOS 11.0 all the way up until iOS 12.1.1, has received its biggest update to date. The update seemingly focuses on optimisation, stability and bug fixes, but that doesn’t mean it has to be boring.

The developer behind unc0ver, pwn20wnd, notes that this is the “The biggest update to unc0ver yet!” Most notably, the jailbreak now properly reloads system daemons, which was a highly requested fix amongst users.

Official changelog follows:

05/23/2019 – v3.1.0 was released for production with the following changes:

  • Rewrite the kernel patches from scratch to improve the stability and the reliability of the jailbreak

  • Rewrite the preference management system from scratch to optimize the jailbreak

  • Rewrite the diagnostics system from scratch to provide more useful information

  • Rewrite unrestrict libary from scratch to improve the stability of the system after jailbreak

  • Add support for switching from the other iOS 12 jailbreaks without restoring the root filesystem and losing data

  • Make Unrestrict add sandbox exceptions for mach_lookup and mach_register

  • Fix issues with processes looking up Substrate port on iOS 12 to fix stability and performance issues

  • Fix support for the broken versions of RocketBootstrap and hid-support tweaks

  • Fix the iMessage audio crash

  • Fix FaceTime calls disappearing on some devices

  • Fix Camera crash on some devices

  • Update the local APT repo to include the latest updates from the Elucubratus repository, including the updated uikittools with rewritten uicache and sbreload commands to make refreshing the icon cache and reloading the SpringBoard significantly faster when installing packages from Cydia

  • Refresh the icon cache during the root filesystem restore to fix jailbreak apps staying on the home screen after restoring the root filesystem

  • Update mobilesubstrate to version 0.9.7033 to disable loader in the securityd daemon to fix a freeze issue on iOS 12

  • Significantly improve the reliability of the jailbreak when using the machswap or the machswap2 exploit

  • Wait for the user to tap OK on the jailbreak completed alert before respringing the device

  • Improve the jailbreak’s self-repairability feature

  • Add a progress HUD to display the status of the jailbreak process

  • Optimize the code

  • Improve assertion

  • Add error-specific error messages

  • Display info about the device on launch

  • Clean up logging

  • Reconfigure the “Reload System Daemons” and “Enable get-task-allow” preferences

  • Make “Enable get-task-allow” a default option

The new update is also supposedly able to improve performance over previous versions thanks to many components being rewritten and changed.

If you’re more of a “fancy new update” guy, there’s a new progress HUD too.
