We have added support for AdWords API v201603 reports in AdWords scripts. The major changes in this release are: See the AdWords API release notes for more details.

Starting from this release, we will not switch to the latest reporting version on the day of the release by default. Instead, we will keep the previous report version as the default version for a while before switching to the latest reports version. This will give you enough time to verify your scripts and make sure it works with the latest report version.

If you use API versioning in your reports, you need to modify your code to use v201603 as shown below.
var report = AdWordsApp.report(query, {
   apiVersion: 'v201603'
If you don’t use API versioning, no code changes are required. Your reports will continue using v201601 for now, and switch to v201603 when we make v201603 the default version on May 17, 2016.

If you have any questions about these changes or AdWords scripts in general, you can post them on our developer forum.
