Google has just announced the release of v12 of the API.

Here are the highlights. Taken directly from the Google Ads Developer Blog.

• Added support for new recommendations: RaiseTargetCpaBidTooLowRecommendation and ForecastingSetTargetRoasRecommendation.
• Added primary_status and primary_status_reasons to Campaign to provide insight into why a campaign is not serving or not serving optimally.
• Added support for linked portfolio bidding strategies and campaign budget. You can modify these links using bulk mutates.
• conversion_tracking_id will always be greater than 0 for all customers. In the previous versions, this field could be 0 for customers who had never created any conversion actions.
• Updated SmartCampaignSuggestService.SuggestKeywordThemes to generate more keyword theme suggestions for Smart campaigns, including free-form keyword themes.
• Local Services campaigns now support individual location targeting, except for proximity targeting.
• Remove CampaignExperimentService in favor of the previously added new experiments.
• Removed support for creating new Smart Display campaigns. To achieve the same goals, we suggest using standard Display campaigns.
• Removed support for creating a new Gmail ad. Use Discovery campaigns instead.
• Removed GenerateProductMixIdeas from ReachPlanService.
• (For allowlisted customers) Added support for adding, updating, and removing CampaignAsset and AdGroupAsset with the field_type: AD_IMAGE (Image assets).
• Added support for mutating and retrieving location asset sets for test accounts only. The location assets for the asset sets are automatically generated and non-mutable.

Update your Client Library. Developers who want to utilize these new features will need to ensure their Client Libraries are updated.
