Python agent v11.2.0

Notes

This release of the Python agent adds support for the following:

• Strands
• AWS Bedrock Converse Streaming
• Redis methods hybrid_search and msetex
• Langchain role assignments for LLM events
• LLM event timestamp captured at time of LLM request
• loop_factory parameter in asyncio.Runner

This release also addresses a bug in ASGI instrumentation where headers are not reported by the web server.

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.

Features

• Add support for Strands

  • Add instrumentation for Strands tools and agents in single and multi-agent (swarms, graphs, etc.) setups

• Add support for AWS Bedrock Converse Streaming

  • Add monitoring support for streaming Converse API. This includes support for Converse chat completion calls made with boto3 and aioboto3 clients using converse_stream().

• Add support for Redis methods

  • Add support for the following methods:
  • hybrid_search
  • msetex

• Add support for loop_factory in asyncio.Runner

  • In Python 3.11, the asyncio.Runner class was added as well as the loop_factory parameter. The loop_factory parameter provides a replacement for loop policies. Now, the loop that is created is instrumented, regardless of whether it is through a global event loop setting or a custom event loop.

• Capture Langchain role assignments in LLM events

  • Langchain LlmChatCompletionMessage events now contains the assigned role from Langchain.

• Capture LLM event timestamp at time of LLM request

  • Previously, the LLM event's timestamp was captured at the time of event creation. Now, it is more accurately captured at the time of the LLM request.

Bug fixes

• ASGI header consumption

  • When an ASGIWebTransaction consumes the headers from a http.response.start event, it was doing so without regard to the allowable input types. When the headers are a generator, the generator was consumed by the call to process_response() leaving no headers remaining for the web server to send. This has now been fixed.

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.
