The behavior of the mouse wheel is changed drastically for both scrolling and the animated zoom in 27.2.0.315!
For some reason the Beta seem too treat one rotation of the wheel as an infinite and uninterrupted one, unless the mouse is moved. It leads to infinite scroll and instant zoom, completely unusable. Please take a look at the screen recordings attached.

27.1.1_wheel.mp4 is how the released version behaves. One tick of the wheel — one step of zoom (with Animated Zoom on), or one scroll step.

27.2.0.315_wheel.mp4 is how the Beta does it. If I don’t move the mouse when I move the wheel, it gets scrolled all the way uninterrupted, and zooms to the extreme in a blink. Just terrible!
