What problem does it solve?
LangChain 1.0 / LangGraph 1.0 introduced breaking changes and migration gaps when upgrading legacy projects. This knowledge patch consolidates guidance on the new agent creation API, middleware system, ToolRuntime, content blocks, structured output, namespace simplifications, and the Deep Agents SDK to help teams align codebases with the latest framework.
Core Features & Use Cases
- Migrates agent creation: from legacy patterns to langchain.agents.create_agent with system_prompt, middleware, and state/context typing.
- Introduces and documents the middleware system, including decorators and class-based middleware patterns.
- Covers ToolRuntime, content blocks, and structured output changes to ensure robust multi-modal outputs and provider-agnostic serialization.
Quick Start
Run the patch to migrate your LangChain 1.0 codebase to the new APIs.
