You can use Wit.ai to manage your app versioning so you can work on the next version while still having a stable production version.
Wit allows you to control your app versions through the API or by using the Wit Configuration window. Versions are represented by tags on a timeline and you can target a specific version by defining a tag in the API parameter.
In the Content Browser, select Content, and then select the Wit Configuration file.
Open the file to show the Wit Configuration window.
Expand Advanced, and then enter the version number in Api Version.
For more information, see the Recipe section of the Wit documentation.
