- Bumps `langchain` to **1.3.2** (patch) - Raises minimum `langgraph` requirement from `>=1.2.1` to `>=1.2.2` langgraph 1.2.2 fixes a race condition where DeltaChannel checkpoint writes could serialize `BaseMessage` objects with `id=None` before `apply_writes()` ran the reducer, causing the same message to appear with a different ID on every `get_state()` call and across resumed invocations (langchain-ai/langgraph#7913). The lockfile will be updated once langgraph 1.2.2 is published to PyPI (langchain-ai/langgraph#7914).
