Snyk has created this PR to fix 1 vulnerabilities in the pip dependencies of this project.

Snyk changed the following file(s):

  • requirements.txt

Merge Risk: High

This upgrade from v0.1.53 to v0.3.80 contains multiple significant breaking changes.

Highlights:

  • Pydantic V2 Migration: All packages now use Pydantic V2 internally, and Pydantic V1 is no longer supported. [1, 8] Any code that subclasses LangChain models (e.g., BaseTool, BaseChatModel) or passes BaseModel objects to LangChain APIs must be updated to Pydantic V2. [8]
  • Python 3.8 Support Dropped: Support for Python 3.8, which reached its end-of-life in October 2024, has been removed. [1]

Source: LangChain v0.3 Announcement
Recommendation: Before merging, developers must refactor code to be compatible with Pydantic V2 and ensure the runtime environment is Python 3.9 or newer.
