Help - setting mouse buttons and mouse wheel

[FireSpy]

So I last played Kerbal 1 in January 

I just came back today and the control bindings and views seem changed. I have tried looking though the settings menu, but I don't see how to bind the mouse buttons and mouse wheel.  

Did something change, and if so, how do I change it back?

Sorry  if this has been discussed before. When I started it up I thought I saw a message about something about the controls, was that this?

Thanks.

Moved to gameplay Questions.

Question is, what did it do, and what does it do now?

It may be me going stupid, but I thought the middle mouse button in flight was the camera move, not the right button, and the middle button is now camera pan.

Also, I thought the left button hold in the builder let you move the camera and select, but is now the left.

And other changes like that. I guess I am retraining now, but it feels weird.

It is odd that there is no way to reassign them in the interface. I thought I could assign buttons before.

Thanks for moving to the correct place.
