Pluggable:

The version of OS X on the new MacBook Pros (late 2016) will not work with existing Certified Thunderbolt 3 docks and adapters (released prior to November 2016). These existing devices use Intel’s Thunderbolt 3 chipset (Alpine Ridge) in combination with the first generation of TI USB-C chipset (TPS65982). Apple requires the 2nd generation TPS65983 chipset for peripherals to be compatible.

It’s not clear to me if this impacts all older docks/adapters, but before I made a purchase, I would verify that the dock or adapter in question is compatible with the new MacBook Pros. Even if you don’t have a 2016 MacBook Pro on order, you might order one at some point. Consider it an effort at future-proofing.
