Just for curiosity, have you pre-programmed an option for you to 
allow free bug releases for expired licenses?

For example, a serious flaw is found in 4.0 and you release 4.0.1 but 
because of the timing, a large number of users affected have expired 
licenses or you decide the fix is so important that it should be 
available to all 4.0 users.

To accommodate this, you need to have an option coded for Valentina 
4.0.1 to recognize the serials applicable for 4.0 AND 4.0.1.

You will also need this when you deliver on the promise of supporting 
the previous branch with bug fixes.

Just thinking ahead :)
