checkra1n 0.12.2 beta update is now available with fixes for iOS 14.3 crashes on A10 and A10X devices. The update also enables USB on Apple TV 4K.
Unlike previously announced, this update still does not make checkra1n open-source, a 2020 target that the development team missed. The team said on Twitter that they are still working on it but it is not ready for a release yet. However, they have been able to release an open-source version of PongoOS along with checkra1n 0.12.2 beta.
checkra1n 0.12.2 beta fixes crashes on A10, A10X devices
For those who do not know, checkra1n allows you to jailbreak iOS 14 on A9, A10, and A10X devices. If your device is already jailbroken with checkra1n, it is advised that you download the latest checkra1n 0.12.2 beta and re-jailbreak to take advantage of the fixes and improvements in this release.
Note that this release does not mention the inclusion of Substitute 2.0.0 which will replace Substrate for improved performance and stability.
Here is the complete changelog for checkra1n 0.12.1 beta:
