Here are the highlights:
- Return metrics for entities not formally supported in the API, such as Discovery campaigns, are now available. These entities will show
UNKNOWNenum values returned. See the release notes for more details.
- New request parameter to opt into returning all mutable fields in the response during a mutate.
- The API is moving towards using field presence such as
optional doubleinstead of wrapper types such as
DoubleValue. Your code will be easier to use and simplifies the API with payloads that are significantly smaller. Approximately half of our resources have been updated in this release. The full list is in the migration guide, and our code examples have been updated. The rest of the resources will change to field presence in a future release.
- Subfields of
AdGroupAd.policy_summaryare now selectable. Non-repeated subfields of
AdGroupAd.policy_summaryare now filterable.
- Support for Keyword Planner:
KeywordPlanKeywordHistoricalMetrics.close_variantsto return the close variant keywords that have been merged to compute the historical metrics.
KeywordPlanService.GenerateForecastTimeSeriesthat returns the weekly forecast trend for Keyword Plan for the next 52 weeks.
