For approximately one week ago, I released a newer version of the SKGL API. This update has no significance to the way you’ve used Software Protector and SKGL before, however, keys generated in the previous versions will not be validated in this release.
This is mainly because of the change to a part of the algorithm that caused a small bug, which was mentioned here.
Fortunately, this bug is fixed, so you can continue to protect your ideas with Software Protector! 🙂
