newrelic 13.1.1

v13.1.1

on Python PyPI

Notes

This release of the Python agent adds additional model information to LangChain Chain LLM events, and fixes a bug in LangGraph streaming instrumentation.

Install the agent using easy_install/pip/distribute via the Python Package Index, using conda via the Conda-Forge Package Index, or download it directly from the New Relic download site.

Improved Features

• Add additional model information to LangChain Chain LLM events

  • Add request.model and response.model attributes to LLM events produced by LangChain Chains.
  • This information is pulled on a best effort basis and may not always be available.

Bugs

• Fix TypeError in LangGraph streaming instrumentation

  • Previously, when using a subset of streaming APIs in LangGraph, the agent would encounter a TypeError due to the use of weakref.WeakMethod by LangGraph. This has been fixed, and the agent should now work correctly with those LangGraph streaming methods.

Support statement

We recommend updating to the latest agent version as soon as it's available. If you can't upgrade to the latest version, update your agents to a version no more than 90 days old. Read more about keeping agents up to date.
