Submit multiple bundle to Blackberry app world

Submit multiple bundle to Blackberry app world

A week ago I have submitted an application which supports Blackberry Z10.
Yesterday, I finished another version which supports Blackberry Q10 and
Blackberry Q5. At the moment, my app on the market is version 3.0 and it
only supports Z10.
If I upload a new bundle, the version of the app automatically increase to
4.0. This bundle also only supports Q10 and Q5 as the previous version
already supported Z10. In this case, what will happen to Z10 users? Will
they receive the update version (4.0), as it is a newer version, although
I already set the specific devices to Q10 and Q5?
In the future, if I make some update, how can I manage it?
Cheers,
