Ok, this is strange. Was at work happily coding along when the API changed. So I changed my code to suit the new results. Now I get home to start refactoring things and it's appears to have been changed back? WTH yahoo?
I also experienced the same thing. We had to scramble to accomodate for the V2 response. Then when it switched back, we had to scramble again to accomodate for both. Does somebody at Yahoo have any information on what happened?
