LangGraph 1.2 launches DeltaChannel for efficient agent checkpointing
DeltaChannel stores only the diff at each step and writes periodic full snapshots, reducing checkpoint storage for a 200-turn coding agent from 5.3GB to 129MB (41× reduction). It is delta-backed by default for messages and files in Deep Agents v0.6, with no API changes.
