Enterprise Version filter no longer available under enrollment restrictions for Android devices in AirWatch 8.4
Prior to AirWatch 8.4, there was a configurable filter available under Settings > Devices & Users > General > Enrollment > Restrictions > Policy Settings labeled Enterprise Version. This filter was only available for Android devices and allowed to specifically whitelist or blacklist certain enterprise versions of devices, such as Samsung or HTC devices.
Over the past several releases of AirWatch the ability to whitelist and blacklist devices has significantly expanded, including the ability to filter by device manufacturer directly. In AirWatch 8.4 the Enterprise Version filter has been removed, with the functionality to restrict by device manufacturer now available both for enterprise and non-enterprise devices under the Manufacturer filter.
