For every release of the HxGN NetWorks Core | Mobile product family, a base suite of automated tests and a set of manual workflow tests are performed before the release is made available to customers.
Regarding customization, backward compatibility with the API of the previous version is maintained so that existing custom code runs after the product upgrades. In the few cases where backward compatibility is not possible because of technological constraints, affects and recommended resolutions are documented in the HxGN NetWorks Core | Mobile Release Notes.
