We have just released version 2 of our SDK for Windows Phone 7.1 (Mango) Silverlight based apps. The SDK introduces a lot of changes and improvements. Here are just a few:

• Support for image ads
• Improved ad loading speeds and reliability
• More and better statistics

These features will “light up” as apps on the network switch to the new version. For example only the apps using the v.2 SDK will be able to upload image ads once we have enough apps to show them, etc.

To make the decision to switch to v.2 easier we’ve decided to give 250,000 free ad impressions to each of the 5 first apps that switch from v.1 SDK to v.2 (not applicable to new apps) and 20,000 free impressions to the next 20.

You can get the SDK from from nuget and implementation instructions are available in the documentation section in client area.
