Probably you are talking about the "Surveyor Trial".
As written there you get "ComfortUpdate for up to 6 updates".
So afterwards you have to update manually (as described in the manual) or buy another package.
As said on that page about the Community Edition:
The free and complete solution for your surveys to be installed on your own webserver.
Add value and update comfortably by using our optional Surveyor Premium Subscriptions.

Volunteers are not paid.
Not because they are worthless, but because they are priceless
