LangGraph 1.1 ships opt-in version="v2" streaming that yields strongly-typed StreamPart dicts with type, namespace, data, and interrupts — eliminating the untyped dict problem that plagued production observability. Pydantic model coercion is automatic. Time-travel with interrupts and subgraphs is fixed. Backward-compatible opt-in; gradual migration via dict-style access on GraphOutput.
