OK guys... you might be ok with your radar scripts if you're using v2. All of my scripts are still working, and it appears may continue working. Assuming they are already sending the wrapped version, we may be fine.
Note: The Google Maps JavaScript API Version 2 was officially deprecated on May 19, 2010. The original deprecation period has been extended from May 19, 2013 until November 19, 2013. As of this date, all applications requesting v2 will be served a special, wrapped version of the v3 API instead. We expect this wrapped version of the API will work for most simple maps, but we strongly encourage you to migrate your code to version 3 of the Maps JavaScript API before this date.
