The LangChain team has officially released the Middleware API, bringing production-grade agent control to LangChain and LangGraph applications. This groundbreaking feature, which we explored at our October showcase, is now live and ready for enterprise deployments.
Our October 2025 monthly showcase was packed with cutting-edge presentations on LangGraph 1.0 middleware, agent-to-agent communication protocols, groundbreaking cancer detection research, and local LLM inference strategies. With over 60 attendees and 6 first-time visitors, the energy was electric as our community explored the future of AI agent architectures.
