    LangGraph 1.2.15 fixes message IDs, cached-node writes, interrupt breakpoints and update_state checkpointing

    Langchain-ai published this on Oct 12, 2026 (source: github.com).

    LangChain AI released LangGraph 1.2.15. The maintenance release assigns an id to every message written to a messages DeltaChannel, saves a cached node’s writes like a node that ran, stops at an interrupt_before breakpoint when a drain is requested before it, keeps an exit run from a checkpoint the thread moved past out of its newer branch, and stores an update_state input’s writes on the correct checkpoint.
