Google has begun rolling out Google Play services 6.1 with a set of new APIs for developers. The new features include an Enhanced Ecommerce extension for analytics, improvements to Drive support, and testing capabilities for the upcoming Google Fit platform.

Enhanced E-commerce provides “richer insights into pre-purchase shopping behavior and into product performance.” The Google Drive API for Android now includes a Completion Events feature. The File Picker UI has been updated with Material Design elements. Google has also added a setParents() method for organizing files.

Google says the update will be rolling out to developers in coming days, with the documentation and SDK coming shortly after.
