LangChain has announced a pre-release of version 0.2, building on the foundation of the initial stable release, LangChain v0.1, by incorporating community feedback and enhancing its architecture and documentation. This update introduces a clear separation between the langchain and langchain-community packages, making the core package more lightweight and secure while retaining backward compatibility. The documentation has been revamped to be versioned and more navigable, reflecting community suggestions for improved discoverability. LangChain v0.2 also sees the introduction of LangGraph for easier customization of agentic workloads, alongside enhanced support for streaming and standardized tool calling. The update aims to maintain stability and reliability for its extensive developer community, ensuring minimal disruption with backward compatibility and a migration CLI to facilitate transitions.
