Shopping Content API
AdWords scripts now support Google Shopping Content API which gives Google Merchant Center users the ability to upload and manage their product listings and manage their Merchant Center accounts. The Shopping Content API can be enabled through the Advanced APIs dialog. See our guide and code snippets to learn more about this feature.

Account level extensions
AdWords scripts now support account-level extensions: AccountCallout, AccountMobileApp, and AccountReview. You can access these extensions using the extensions() method of the Account object. Appropriate creation and deletion methods are also available for these extensions on the Account object. See our guide for more details and usage examples.

Resolve geo names in reports
The method now supports an option named resolveGeoNames, which controls whether or not to convert Geo Criteria IDs (e.g., CountryCriteriaId or CityCriteriaId) into names ('United States', 'San Francisco', etc.). Set this option to true to get names, false to get numerical IDs. This option defaults to true.
