The McLaren do not have the slots in front of the rear wheel. So can someone explain how do they seal the floor?

The holes in front of the rear wheel are not for sealing the floor, they are there to manage tire squirt. Do a google search for that term and you'll find quite a lot

From FP3. Flowviz on the front wing, near the exhaust (from the T-wing). I'm spotting nothing on that rear wing. It was supposed to be new?

Fernando is confident, it seems to work...

Another one from the new rear wing:

I only spot a piece of black paintjob and maybe a different curve on the lower front edge?

I remember seeing remnants of flow vis under the diffuser left side only (Sky sport slow motion shot in Q2) Unfortunately I have no images of that

I don't think those are different. There's a slightly different angle. The green arrow shows the black edge of the main pain but due to the angle it's not visible in the lower pic. Just take the 'n' of MacLaren as a reference. The yellow arrow I doubt very much, I think it's lighting. Here's one from Melbourne for reference.

I rechecked that clip. I was mistaken about seeing flow vis on there. Sorry

They didn't end up running with the new wing for the race and reverted back to the original one. We'll likely see it in Bahrain next week.

McLaren brought a new floor to Shanghai, characterised by a meter-long longitudinal slit. Basically, this serves to isolate the air flowing under the car so the diffuser can work more efficiently. A similar opening can be found on the Mercedes, Ferrari, Toro Rosso, and Red Bull, albeit in a different shape for the latter.

The rationale is the same as the floor slots ahead of the rear wheels, i.e to allow high-pressure air above the floor to go under the car in order to seal the edges of the diffuser.

How does it work? The encounter between low-pressure and high-pressure air generates a vortex that acts as a wall to protect the diffuser from the dirty wake of the rotating rear tyres.

Sealing the diffuser’s edges is all the more important this year with teams running higher rake angle on their 2017-spec cars, which is especially true of the McLaren-Honda MCL32.
