Was there a change in user agent from pre-0.3.1 version to latest? I realize we couldn't change user agent pre-0.3.1, but was the built-in one different from the default user agent now?

I only ask because I used to be able to watch dailymotion videos very easily through google video. (For example.) But now I have the hardest time getting the videos to play. And I can't recall exactly how, but I believe that those google video search results pages used to handle differently before the upgrade, which leads me to wonder about a user agent page.

Forgive me if I'm barking up the wrong tree.
