I received an invitation to join this beta today. Among the advertised highlights are –
Support for Windows, Office, SQL, and Exchange patches
Reporting capabilities – deployment status about download, install and impacted machines.
Ability to uninstall patches that support uninstall
More Administrative controls – patch install, uninstall, install by a deadline, and configurable client polling intervals.
Targeting of different updates to administrator defined groups of machines.
They should really have been in version 1!
