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.

<span class=“card-start” data-card-raw=“title=“Stable core APIs” icon=“sitemap”"> Graph primitives (state, nodes, edges) and the execution/runtime model are unchanged, making upgrades straightforward.

<span class=“card-start” data-card-raw=“title=“Reliability, by default” icon=“database”"> Durable execution with checkpointing, persistence, streaming, and human-in-the-loop continues to be first-class.

<span class=“card-start” data-card-raw=“title=“Seamless with LangChain v1” icon=“link”"> LangChain’s create_agent runs on LangGraph. Use LangChain for a fast start; drop to LangGraph for custom orchestration.

To upgrade,

pip install -U langgraph

uv add langgraph

Deprecation 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.

• For information on the new create_agent API, see the LangChain v1 release notes.
• For information on migrating from create_react_agent to create_agent, see the LangChain v1 migration guide.
