For as long as iOS has been around, there’s been the need to get a little more functionality than Apple builds onto the OS. This led to the birth of the whole jailbreaking community. One popular tool to accomplish this has been checkra1n.

checkra1n jailbreak is considered by many, the new generation jailbreaking tool. It is based on the permanent unpatchable bootrom exploit called checkm8 by axi0mX.

This update also brings a new CLI, an experimental web-based UI called webra1n, and a lot more. The web-based UI is particularly interesting because that means checkra1n can now be deployed on headless computers like Raspberry Pi. Below is the update’s changelog.
