The upgrade of langchain-core from 0.1.53 to 0.3.81 is high risk, while the marshmallow upgrade is medium risk.

• langchain-core (0.1.53 → 0.3.81): High Risk

  • This upgrade forces a migration from Pydantic v1 to v2 and drops support for Python 3.8. Pydantic v2 has significant API differences from v1, which will require code changes for any projects using Pydantic models with LangChain.

• marshmallow (3.22.0 → 3.26.2): Medium Risk

  • This upgrade drops support for Python 3.8. It also introduces a breaking change where custom validators must raise a ValidationError instead of returning False.

Recommendation: Prioritize addressing the langchain-core upgrade. The mandatory migration to Pydantic v2 requires careful code review and refactoring before this change can be merged.
