The issue is that now a button release is only issued after the finger
has completely left the touchpad and not when releasing the physical
button. Is this physical button now called FORCEPAD? Anyway, this is
pretty annoying. Double clicking become a real pain.

I'm also experiencing this, but wanted to add that it happens on only one of
two T440s laptops I've used recently.
