Just a couple of changes:
Expanding on the new capability of the Fill Between Curves command, you can now fill the area between a single curve and a horizontal line with a specified Y value. You can also specify different colors for the areas above and below the line.
Axes at 0 tick marks, labels, and line(s) are no longer obscured by curves or fills between curves.
