Now the hype train starts all over again… Please talk a little more about this integration? And what about plans to integrate Valkyrie into CIS?

Oh, one thing guys: Is this release compatible with latest Redstone Win 10 build? I heard that this build is making antivirus vendors crazy about compatibility issues…
