The upcoming version (due out in a few weeks) of the OpenG Builder will allow versioning applications. The builder can write this version data to a cluster control's default value on a specified VI's FP during the build, so that the built application can read it. It also allows incrementing a build number each time the application is built.
The LabVIEW App Builder does allow creating versions, when using the "Create Installer" feature (Windows only).
Stay tuned. Visit
OpenG.org for more info.
