Following the launch of checkra1n version 0.12.3, which added official support for A7 and A11 devices running iOS & iPadOS 14.5, Saurik was quick to update Cydia Substrate so that those devices could enjoy reliable tweak injection.
But Cydia Substrate isn’t the only tweak injection method that works on the checkra1n jailbreak. So too does Substitute, and users of this alternative will likely be looking for a similar update. Fortunately for those folks, said update is now available in the form of Substitute version 2.0.11.
