LangChainAI has announced the release of LangChain v0.3 for both Python and JavaScript. The new version includes significant updates, such as migrating Python to Pydantic 2 and moving JavaScript to peer dependencies. These changes aim to improve dependency management and simplify upgrades. The release also introduces structured outputs and enhances the overall functionality of the framework. Additionally, LangGraph workflows can now be called from Next.Js applications, further integrating Action/NLP capabilities.
🥳 LangChain.js v0.3 is live! The major change is that `@langchain/core` is now a peer dependency of all packages. This makes upgrading simpler and prevents type issues from npm resolving multiple core versions. Full list of changes + upgrade guide: https://t.co/b5TEGN0TSN https://t.co/zuxcr7C1yr
