Sorry, I don't.
Since Infopop is allowing full template distribution, I had no plans at all of even having an "instructions only" version, so there isn't a changelog of any sort. The best thing I can tell you to do, if you really do require something like that, is get Beyond Compare, and compare Allen's normal XHTML templates to my CH2 templates and find the changes yourself. That would be the best, if not only way to use instruction-based hacking instead of the whole template files.
Yes, these were really meant to use as a starting point on a clean board.
