What is your upgrade policy?
Firstly, our upgrade policy only takes effect on our registered users. Once there is a bug fixed or some certain function is modified or optimized, an upgrade will be arranged and soon there will be a new version released.
Commonly, the upgrade is minor upgrade, such as upgrade from 1.1.1 to 1.1.2 or 1.1.1 to 1.2.1. This minor upgrade is free for all our registered users.
Also, sometimes the program may be modified a lot or some functions are added, then this kind of upgrade is called major upgrade. Its version number will be changed a lot too, such as from 1.1.1 to 2.x.x. Usually, major upgrade needs payment of a little amount of fee as upgrade charge.
All the upgrade news will be also posted on our webpage in time for your information.
