Here’s what’s changing:
→ Full management of advertiser-level YouTube video and channel exclusions.
→ Support for Digital Out of Home insertion orders.
→ Updated inventory source retrieval and targeting.
→ Reworked audience targeting for Demand Gen and YouTube ad groups.
One migration change deserves extra attention:
Customer Match audience management is removed in v5. Integrations using those features will need to use the Data Manager API.
If you maintain DV360 integrations, now is a good time to review the v4 → v5 migration guide and assess the impact on your workflows.
Update your client library before testing the new features.
And keep the beta status in mind: Google may introduce breaking changes, which will be documented in the release notes.
