Citrix iApp and 11.6.4

When I look at the documentation for the new iApp for Citrix VDI (v2.1), it says the supported version 11.4.0 to 11.6.0. We are currently running 11.6.4, so does this mean we cannot use the iApp template? I figured it would be fine assuming of course that all iApp versions are tested against the CodeBase.
