Hi,
You won't have to buy a new full license. We will sell a 1 year support/update contract which will be a small percentage of a full license. If you don't buy it, you don't get the updates after 1 year. If you do you keep getting them.
Also, if you buy a new license for a second website, you get your support/update contract extended automatically as the contract is for all the websites of a user.
That means that if you're planning on creating at least one website per year with HikaShop, you won't pay for it as and you will get the updates thanks to the licenses.
Note that for now, the system is not in place for that and as long as we don't put it in place, you will be able to update without buying anything.
Also, if there is a security issue found in HikaShop,we would provide the new version for everyone, regardless of support contracts.
