langgraph
Update 07/2026: LangGraph reached 1.0 in October 2025 and is now the runtime underneath LangChain's create_agent - its role changed from "LangChain extension" to the foundation of the ecosystem. It is widely considered the de-facto standard for production agent orchestration.
Notable since 1.0: node-level timeouts and error recovery, reduced checkpoint overhead and a new streaming API (releases).
