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.
