Google has released version 2.0 of their Play Services for Android applications. The new additions represent the Maps and Photo Sphere APIs, and are available for all applications running on Android 2.2+.
The new version of the Bing AJAX Map Control version 7 is one third the size of the previous version, a huge win for web sites that cater to mobile device users. Controls have been reduced in size and given HTML 5 support. There have also been performance improvements for multiple-point rendering.
