Identical to the 2015 model but now with 8GB standard RAM.
Has a Thunderbolt 2 port, 2 x USB 3.0 ports, SDXC card slot. Mac OS X 10.11 El Capitan installed. Probably one of the last models with this multi-port form factor.
The new model replaces the old iPad Air line. It's a bit heavier, but it has a brighter display and the 1.85GHz A9 CPU. Oh, and they kept the headphone jack.
