When is the latest version going to be released to Support Surface Pro 4's
Is 1666 a beta version ? ( I have tried this on my Surface Pro 4's and was able to create an image, but I have not tried to deploy the image to another one yet )
If so when will the newest version be realeased ?
It's beta - I have no idea when an official update or upgrade will be released though. As far as I can tell, 1662 is the same as 1660 but with newer intel NIC drivers and 1666 is the same but just added NVME driver support.
