[1] PTF required DMO04001
When testing for support of new operating systems and subsystems, Macro 4's policy is to only test the current GA (General Availability) and EA (Early Availability) releases.
Macro 4 always recommend customers upgrade to the current release of software. We offer full support for current releases and will provide, where possible, fixes to older releases via a patch mechanism. In some cases a full upgrade to the current release may be required.
