I thought in that before, but I think this is also made for compatibility purposes. Does anyone tried to install 0m7 / 0m8 packages on PR1.0 / PR 1.1. I heard QML / QtQuick made apps break compatibility on PR1.2 because of new build-in version, is that true? may be is because of this?

I will check if i can install the new 0m8 facebook version without update PR1.3, and once update to new firmware, try to install old version. Will report later.
