The slow to react stereo panners ( issue introduced in 9.5.2 ) are still present and a little frustrating if you mainly use a mouse. So for me it’s a No untill that’s sorted.

It would be nice if Steinberg made an official statement on what is going on in this update, if there are no issues with it. Or if they pulled it for the time being, if it is as bugridden as the user responses indicate.
Right now, I cannot decide to install it, which makes me sad.
