I would want more detail about the code, and any bug fixes that you
have to incorporate. Of course, if the new book covers more topics
than the chapter(s) of the old book, you have the potential to use
some of those extra features and update the code that way, too. If you
don't have anything new to add to the code you have, you can start
with an older version and show its evolution into the current form.
