Mine came from Amazon this week, as well. I’ll look at the box later and see if it has any sort of new/improved markings, dates, firmware printed on the box, or anything like it.
ETA: Nothing obvious on the box, just the device serial# and the S2 DSK. Doesn't look like much, if anything, on the unit either. It does have a SKU# of 4AR1S70EN0.
