We have added support for AdWords API v201609 reports in AdWords Scripts. The major changes in this release are:
See the AdWords API 
release notes for more details.
The v201607 will remain the default version for reports until the week of 
November 28, 2016. This gives you enough time to verify your scripts and make sure they work with the latest report version.
If you use 
API versioning in your reports, you need to modify your code to use v201609:
var report = AdWordsApp.report(query {
  apiVersion: 'v201609'
});
If you don't use API versioning, no code changes are required. Your reports will continue using v201607 for now, and switch to v201609 when we make v201609 the default version the week of 
November 28, 2016.
If you have any questions about these changes or AdWords scripts in general, you can post them on our 
developer forum.
