Upgrades are free for any versions that have the same major revision number. For example, if you were to license version 22.214.171.124, then any subsequent release with the same major revision number, such as v 126.96.36.199 or v 188.8.131.52, is a free update.
The program files are identical for the licensed and evaluation versions of ShortKeys.
In the event of a new major release (i.e. v5.0), an upgrade fee will be required.
