Apple's iAd Producer has been quietly updated to version 2.1, which addresses a number of minor improvements such as support for the latest iPad and faster loading, saving and exporting of projects. The marquee feature, however, is iAd integration with Twitter -- allowing iAd designers to integrate Twitter directly into the ad. Also integrated into v2.1 is the use of WebGL assets in iAd content, and an expansion of types of assets that are allowed.
