Handle Version Numbers
Version numbers are only incremted when a new build of an app is published on the App Store. (App Store update).
The version number update must be effected in the App Manager manually.
For major updates the version number is incremented to the next full number (e.g. 2.0), for minor updates the version number can be incremented to a decimal number (1.1. or even 1.1.2 if desired). This is has communicative value only.
