As all of our products updates will be free through sub-point versions. This means that all versions from 1.00 up to 1.99 will be free upgrade for all users.
I guess that users who use other products we have, like PocketBreeze, already know we don't release major release every two days
We released PB 4.0 5 months ago, we had about 55 updates since then, all of them with new features, and we are only getting to version 4.2 in about two weeks, so we don't see version 5 of PB in the next 5-6 months

we believe this is pretty fair.
