There's not card for the 0.7.1 release -- but it's an important one. Strongly recommended over 0.7.0. But then, 0.8.0 is even more highly recommended ;).
Since 0.7 introduces case and pluralization insensitivity, you will have to work through some conflicts in your data if you ever had separate cards for different case variations. If, for instance, you had a card for "polish" and one for "Polish", our migration would choose one of these and add the word "CopyCard" onto the end of it. So, after you migrate, just search for CopyCard, and if anything turns up, get to fixin!
