Google announced DoubleClick Bid Manager API v1.1. Two major changes affect queries and reports methods. All other API methods remain the same in the v1.1 release. Report columns are now mapped one to one to API filters, and query/report resource responses are now paginated.
Google has been at work on its replacement for the AdWords API. The Google Ads API is a more modern API that will soon have all features from the AdWords API and more. The new API just moved from beta to production ready. The beta version will sunset at the end of April 2019.
