Sorry for the bother, and thanks to Tom Van Cutsem for catching another typo. In the process of fixing that I did a bit of very, very minor cleanup.
So the PDF and EPUB versions now on the public site are slight revisions.
If you have somehow committed to the previous (e.g., printed it), the only thing you will care about is that on page 79–80, there was an error in the "Macro Stepper" coloring that is now fixed. Just check those two pages afresh.
An easy way to tell you have the right file is that in the new version, the source program is now blue, and the macro-generated code is red (flipping what it was before, and consistent with the Racket Macro Stepper's first color for macros).
