Cowling, Air inlet got replaced. A part for testing maybe?

Sorry, I did not understand which part you were talking about? couldn't see any difference

I am not an expert or an aero engineer, is it me or this one is also shaking like first prototype.. Helicopter still has some vibration and don't look stabilized to me, which would extend test process if it is true. First flight was 3 years ago.. I thought it would become more stabilized in time. This one truely looks like finished product and should be better than other two.

The helicopter is flying perfectly. It is extremely stable. The helicopter encountered no vibration issue since its first flight and this is very rare in helicopter development. The transmission and rotor have perfect coherence with the body.

To me it looks like the nose is going a little bit up but it may be an illusion by the edit of the video.

I posted the tweet from my museum object, but watching the video again it looks very stable only a slight wobble can be seen when it's rotating, but I'd assume that it's normal because they're doing small scale turning around.

I'd really like to see it moving from point A to B at different altitude and speed to get a better impression on how it's doing (including take off and landing).

That maybe correct as I see an extension tube attached to the front. I am not 100% sure what this tube is used for but I think it is a weight balance to balance the weight between the front of the mast and the back. As every piece of equipment added to the body creates a shift in the center of gravity of the helicopter they need to find out empirically how much counter balance should be added or how far from the center the weights need to be moved. This experimenting should be remade until the last piece of weight/equipment is added. My two cents.
