We are promoting Display & Video 360 API v4 from beta to general availability, making it the recommended version. Updated guides now reflect v4 features and conventions.
Migration from v3 to v4 is advised as v3 will be deprecated soon. Instructions for migration can be found in the migration guide, and a detailed list of changes is available in the February 13, 2025 release notes. Ensure your client library is updated to the latest version before using v4.
