I saw this too, and I'm surprised this is the first post about it. I'm running fine on 208 right now, not sure if I should rush into installing 216 yet.
Looks like they updated the Intel Raid driver to 14.8.0 but I would need to try a clean install to see if the Samsung 950Pro is detected correctly. I tried to brin up Clonzilla to back up my current drive but it doesnt see the nvme drive
