Question about Teaching Textbook Algebra 1 versions

I’m wondering if any of you know whether there is much difference between the version 1.0 & version 2.0 work texts for TT Algebra 1? I know there are differences in the cd tests (automatic grading, for instance), but I am wondering if the work text from version 1.0 would align properly with the cd lessons from version 2.0 (and vice versa).

I found a good price on a used set that has everything but the work text, so now I’m hoping to find a copy of the work text to go with it.
