What is the perpetual license and how does it work?
When you purchase a Network Magic version, such as 5.0, the perpetual license agreement means that you get any other 5.x version updates for no additional cost. For example, if you purchase Network Magic 5.0, then you get Network Magic 5.1 for free. Upgrades to a new version number, such as Network Magic 6.0 may require additional payment.
