You can recreate the old H&S adjustments - see Kirby Krieger's Thread:
Basically you use an image, that still has the Version 3.2 Highlights & Shadows adjustments and create an adjustment preset (effect) from this image. Then you can use the advanced controls again for all images.
I suggest reading these two comments as well:
I have since bound this to a keyboard shortcut in Aperture using "Aperture➞Commands➞Customize". I recommend finishing the set-up by assigning the Effect (which is null until you change the sliders) to a keyboard shortcut.
... The new Brick is more useful than I first thought. Like you, I was used to the _scale_ of the sliders in the old Brick, and shocked to find that what I had internalized as "enough" had become "not visible".
You have to train your mouse-hand with the new Brick's sliders as a totally new Brick, not as a modified version of the old Brick. Now that I am comfortable with the scale (and the variation within the scale, as you point out), the new Brick is nowhere near as useless (and offensive for this) as I first judged it to be.
