2.0.0 (2026-08-20)

⚠ BREAKING CHANGES

  • workflow: LLMAgentWrapper and LLMAgentWrapperConfig are removed. An agent is a workflow node as itself — pass it to an edge or node() directly. A non-LlmAgent agent used as a node no longer has the node input appended to its conversation, nor its final model text promoted to the node output.
  • workflow: InvocationContext.agent is now optional. Code reading it outside an agent's own execution must handle undefined; inside one, prefer requireAgent(ctx).

Features

  • core: accept a bare Workflow as a root — runner, App and agent loader (#680) (b3497e0)
  • dev: render graph workflows in the dev UI agent graph (#654) (434a43e)
  • dev: serve the agent structure graph the dev UI's graph tab asks for (#694) (8915c2b)
  • tools: FunctionTool require_confirmation — HITL approval (Part 7) (#594) (d2ae57b)
  • workflow: drive workflows as nodes and remove WorkflowAgent (#688) (534546f)
