LangGraph 1.2.7 fixes state overwrite behaviour across supersteps
The signed LangGraph 1.2.7 release fixes how DeltaChannel overwrite state behaves across supersteps and ensures overwrite markers survive JSON round-trips. Dependency updates include LangSmith.
Impact: state-serialization defects can create silent workflow divergence. Teams should replay real checkpoints and verify deterministic recovery before production upgrades.
