Hello Marko,
If you are using Meego Qt components like infobanner, it makes app incompatible with PR 1.1 and below.
If you can mail developee support about the problem and ask them to pass only for PR1.2 and 1.3 then it'd be alright.
Also include the compatibility note in description in store.
I believe no one uses PR 1.1 now

Cheers,
Bibek
