Your app's content can be indexed and shown as deep links in Google search results if deep links are reported.

The Google Wallet API has added offer support to the "Save to Wallet" button. Users can now tap the button to save offers from an app and have them show up in Google Wallet. Users can receive location-based notifications to scan these digital cards when checking out. Payments can also now be split between a users Google Wallet balance and the credit or debit card associated with their Wallet.

The Google Play game services updates contain a couple of major additons. Quests are a new set of APIs that can run time-based player goals and reward players without the need to update your game. You send game activity to the service when a player successfully completes a level or task. Saved games, meanwhile, allow you to store a player's saved progress in the cloud so it can be accessed on multiple devices. Stored data can include a cover image and description for greater context, as well as time played.
