I didn't see those updates, but I was all caught up as of my first email (I see you did a small merge since then but it looks like only docs changes). When I forked satchmo and then ran all the tests I received a quite few errors. First the Product.site and Category.site (and a few others) were all "1" in the fixtures where they should have been . I'm guessing the tests weren't updated when the site field when from ForeignKey to ManyToMany. I've almost fixed all of these and will have a pull request soon. I just wanted to make sure that the tests themselves were broken and it's not just me messing up.
