MJ3 for MJ2 users

I just bought MJ2 a few weeks ago. Now I see there is already a new version. Of course I like to have it, but I don’t wonna pay the full amount again.
Is it possible to have a upgrade ?

There will be upgrades available, if you purchased from disc4you, you can already order the update for a reduced price. For all others, upgrades will be available within the next 1-2 weeks I suppose.
