Google announced the discharge of Google Play Services version 4.0 today, consisting of the Google Mobile Ads SDK and enhancements to Google+, geofencing, and Google Wallet Instant Buy APIs.

This time around, they’re dropping support for Froyo. Froyo devices won’t be able to make use of the brand new APIs.

“If you’re using AdMob to monetize your apps, the hot Google Mobile Ads SDK in Google Play services helps provide seamless improvements on your users,” says Google in a blog post. “For example, bug fixes get pushed automatically to users without you having to do anything. Inspect the post at the Google Ads Developer Blog for more details.”

“The Maps and Geofencing APIs that launched in Google Play services 3.1 has been updated to enhance overall battery efficiency and responsiveness,” Google adds. “You can save power by requesting larger latency values for notifications alerting your app to users entering or exiting geofences, or request that entry alerts are sent only after a user stays within a geofence for a specified time period. Setting generous dwell times helps to eliminate unwanted notifications when a user passes near a geofence or their location is seen to head across a boundary.”

Apps that use Google+ sign-in can be updated with a brand new consent dialog and Wallet Instant Buy APIs come in for all to aim within a sandbox. These include a brand new API that streamlines the buy-flow and decreases integration time, based on Google. Instant Buy also includes new Wallet Objects.

Finally, there’s a brand new anonymous identifier for ads, for use in preference to Android ID. More at the update here.

Google, obviously, also detailed KitKat today. Here’s what developers want to know.

Google Play Services 4.0 continues to be within the means of rolling out to Android devices.
