Launching Long-Term Memory Support in LangGraph

LangGraph introduces long-term memory support for its AI applications, enabling agents to store and recall information between conversations. This feature is part of the OSS library and is enabled by default for all LangGraph Cloud & Studio users. The initial memory support is built as a simple document store, allowing high-level abstractions to be easily constructed on top. Cross-thread memory extends state management capabilities across multiple conversation threads, providing persistence, flexible namespacing, JSON document storage, and content-based filtering. A new LangGraph template demonstrates how to implement long-term memory in applications, with resources including tutorial videos and sample code in Python and JavaScript.
