The API introduces a new onlineEvaluators.operations resource, enabling standard LRO management (get, list, cancel, delete) for evaluation tasks. Significant deprecations hit GenerationConfig: the fields response_schema, response_mime_type, response_json_schema, and image_config are now deprecated, with developers directed to use the new response_format field. Additionally, PersistentDiskSpec has been expanded to support Hyperdisk types (including hyperdisk-ml and hyperdisk-balanced), and Google Maps grounding widgets are being phased out. Note the documentation shift where 'Vertex AI' is being rebranded as 'Agent Platform' in several resource descriptions.
