Security researcher John Åkerblom took everyone by surprise in April after releasing a kernel exploit for iOS & iPadOS 15.0-15.1.1. Setting this exploit apart from the one initially released by b1n4r1b01 was how it could be adapted to support the latest versions of iOS & iPadOS 14, up to and including 14.8.1.
