还没翻译译自英文（docs.langchain.com）本页 15 段都还没译
LangGraph v1 is a stability-focused release for the agent runtime. It keeps the core graph APIs and execution model unchanged, while refining type safety, docs, and developer ergonomics.
It's designed to work hand-in-hand with LangChain v1 (whose create_agent is built on LangGraph) so you can start high-level and drop down to granular control when needed.
Stable core APIs
Graph primitives (state, nodes, edges) and the execution/runtime model are unchanged, making upgrades straightforward.
Reliability, by default
Durable execution with checkpointing, persistence, streaming, and human-in-the-loop continues to be first-class.
Seamless with LangChain v1
LangChain's create_agent runs on LangGraph. Use LangChain for a fast start; drop to LangGraph for custom orchestration.
To upgrade,
pip install -U langgraphuv add langgraphDeprecation of create_react_agent
The LangGraph create_react_agent prebuilt has been deprecated in favor of LangChain's create_agent. It provides a simpler interface, and offers greater customization potential through the introduction of middleware.

create_agentAPI, see the LangChain v1 release notes. - For information on migrating from
create_react_agenttocreate_agent, see the LangChain v1 migration guide.
