Also routes synchronous FunctionNode tools to the tool thread pool. - Workflows & Approvals : Added require confirmation to enforce human-in-the-loop validation before workflow node execution. - Deployment & Security : Added custom service account specification when deploying agents to Agent Engine, session-level Google credential encryption, and skill-level security in AgentCardBuilder . - Compatibility & Migration : Added support for Python 3.15, migrated to google-cloud-aiplatform v2.2, moved VertexAiExampleStore and VertexAiRagRetrieval out of vertexai.preview , and switched GCPSkillRegistry.search from GET to POST.","sponsors":[]}
