Apparently they have made the bogs negative pressure zones and the air is taken separately back to the dump valve area to be dumped so it doesn't go into the recirc air.
The cabin overhead bins are massive as well and seem to have a sensible realistic weight limit on them.
"negative pressure zones" is meaningless nonsense. They are ventilated along with the ebays into the underfloor area by the outflow valve exactly like the Ejets 15 years earlier.
Nothing new here.
