The new iLok is fully backward compatible with previous versions – so all software developed for use with a 2nd generation iLok will continue to work with a 3rd generation iLok. The design of the 3rd generation iLok is a huge step up from previous versions. The internal components are ingeniously small, packed into their metal case using methods that make duplication virtually impossible. And fewer components means fewer points of failure once the device is being used in the field.
