[The award goes to John Casasanta of taptaptap for the Camera+ release notes](http://taptaptap.com/blog/look-over-there-pal-its-camera-4-2/):
> And then we thought about jumping on the bandwagon where we put Camera+ out as a whole new app and let existing customers pay for it all over again. And of course there’d be the ensuing sh__storm where those customers felt cheated and we’d have to backpedal and reverse that shortsighted decision.
> So it was Clear that that would’ve been a knuckleheaded move, so instead we decided to treat our lovely customers fairly and make Camera+ 4.1 a free update as we’ve always done. But then we felt like it was all give and no take… so to make us feel better about giving-in too easily, we chose to call it version 4.2. That’ll teach you to mess with us.
