Your license never expires for the purchased feature set. Included are also any new premium features for a year starting from the first activation (beta included).
To unlock new premium features added after that year, you can renew the license at a 50% discount for another year – choice is yours if you see something interesting in the
changelogs, anytime.
Renewals append a year from the day of activated upgrade, plus any remainder from the previous license, and resets the activation count.
As an example,
a premium feature can be a new component removal,
Windows version support or a new functionality of the tool.
If you choose not to extend the license premium feature upgrades, your existing license will continue to work with future versions anyway, getting all the bug fixes for your set of features accumulated through the previous year for as long as the tool supports the given Windows version.
