I'm seeing two new settings on the Ad Serving tab under the Allow & Block Ads tab.
1. Enhanced display ads - show performance-enhancing features on display ads.
2. Animated display ads - show animated display ads.
Right now the pop-up description for the features is throwing an error but if number 2 works the way I think it does, I've been wanting this for some time i.e. a way to turn off flash ads. Not sure what the Enhanced display ads feature is exactly about but we'll see. I guess.
Just an FYI so you can check it out.
