Each version set must be tested, to verify that it's used in that installation. 

Note that we won't re-verify each other version-sets, but in theory it's possible to break older installs if your package has a version number which would make it preferrable to older version-sets. 

1. In a test environment of a DNN version matching the requirements (usually 7.4.2), create a new portal
2. Add the app-module to a page in that portal
3. Look at the auto-installer, check if the newly changed package points to the right app in the app-catalog
4. run the installer, verify that the expected apps are included
