Python agent release notesRSS

Notes

This release of the Python agent adds support for aioredis, enhances support for redis and aredis, and fixes a deprecation.

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

New features

• Add support for aioredis

  The agent will now automatically instrument and send metrics for applications using the Redis and StrictRedis clients for aioredis.

Improvements

• Enhance support for redis and aredis

  The agent now instruments a more extensive list of commands for redis and aredis clients. This includes commands under the search, graph, time series, json, sentinel, and bf modules.

Bug Fixes

• Fix threading.currentThread deprecation

  threading.currentThread was deprecated in Python 3.10 and has been replaced with threading.current_thread. Thank you hugovk for your contribution to the agent!

Support statement

New Relic recommends that you upgrade the agent regularly and at a minimum every 3 months. As of this release, the oldest supported version is 5.0.0.124.

Notes

This release of the Python agent adds APM logs in context. Additionally this release fixes issues in Starlette and gRPC version compatibility, renames whitelist settings, and removes unwanted error logs.

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

New features

• Add APM logs in context

  A quick way to view logs no matter where you are in the platform.

  To learn more, see the documentation about APM logs in context.

  • Add support for logging metrics

    Logging metrics show the rate of log messages by severity in the logs chart in the APM Summary view. This is enabled by default in this release.

  • Add support for forwarding application logs to New Relic

    This automatically sends application logs that have been enriched to power APM logs in context. This is disabled by default in this release. This will be on by default in a future release. For more information, see our documentation about logs in context for Python.

  • Add support for enriching application logs written to disk or standard out

    This can be used with another log forwarder to power APM logs in context if in-agent log forwarding is not desired. We recommend enabling either log forwarding or local log decorating, but not both features. This is disabled by default in this release.

Changes

• Rename Whitelist Setting to Allowlist

  The setting strip_exception_messages.whitelist has been renamed to the more modern name strip_exception_messages.allowlist. The original setting will continue to function but issue a deprecation warning.

Bug Fixes

• Fix incompatibility with gRPC v4

  Previously a crash was possible in the agent when gRPC v4 was installed when not using the infinite tracing feature. This has been corrected and the agent can safely be used with gRPC v4.

• Fix Starlette v0.19.1+ instrumentation

  • A crash in CustomRoutes in Starlette v0.19.1 has been addressed and fixed.
  • Starlette v0.20.1 reorganized important files which were then uninstrumented. This has been fixed.

• Fix unhelpful error messages appearing outside of debug logs

  Error messages related to context propagation have been demoted to debug logs to avoid unwanted and unhelpful messages appearing in logs.

Notes

This release of the Python agent adds CodeStream integration support which includes code level metrics.

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

New features

• Add integration with CodeStream Now Introducing Code-Level Metrics! Golden Signals visible in your IDE through New Relic CodeStream. Learn more here. For any issues or direct feedback, please reach out to support@codestream.com

Notes

This release of the Python agent adds support for GraphQL Server, adds a log handler which forwards logs to the New Relic API, and increases functionality to notice_error.

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

New features

• Add support for GraphQL Server The agent will now automatically instrument and send metrics for applications using the GraphQL Server.

• Add a Log Handler The agent is now able to forward logs to the New Relic API. Thank you to iamr0b0tx for your contribution!

Changes

• More Robust should_ignore_error calls Pass references to settings where possible to should_ignore_error and makes custom _nr_ignored logic more defined and incorporated into notice_error.

Notes

This release of the Python agent adds support for Aredis, upgrades to the AWS metadata endpoint to IMDSv2, and fixes attribute errors with the garbage collector sampler.

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

New features

• Add support for Aredis The agent will now automatically instrument and send metrics for applications using the StrictRedis client from Aredis.

Changes

• Upgrades to the AWS Metadata Endpoint Upgrades the AWS metadata endpoint to IMDSv2.

Bug fixes

• Fix Garbage Collection Sampler Attribute Errors A crash caused by an attribute error on the garbage collector sampler has been fixed.

• Safeguards Against Lost Data with Infinite Tracing Fixed race condition between agent and gRPC that resulted in loss of data on agent reconnect.

Notes

This release of the Python agent adds support for Django v4, Redis v4, GraphQL v3.2, as well as fixes to the memory sample exception, Graphene framework, and import hook warnings for Python 3.10.

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

New features

• Add support for Django v4 The agent will now automatically instrument and send metrics for applications using Django v4.

• Add support for Redis v4 The agent will now automatically instrument and send metrics for applications using Redis v4.

• Add support for graphql-core v3.2.0 The agent will support the latest version of GraphQL.

Changes

• Fix Graphene framework details Data on graphene framework details was missing on newer versions, this has been fixed.

Bug fixes

• Fix memory sample exception This fixes the crash in memory sampler on non-supported systems.

• Fix import hook warnings for Python 3.10 An ImportWarning that was emitted when importing the agent in Python 3.10 has been corrected.

Notes

This release of the Python agent fixes an issue with infinite tracing's usage of gRPC allowing subchannels to retry, and fixes failing database traces.

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

Bug Fixes

• Fix gRPC retry logic

  Previously gRPC subchannels left open by infinite tracing could cause network congestion and strain our trace observers. This issue has been corrected. As such, specific versions of gRPC are no longer required.

• Fix crash in database trace

  A crash in database traces resulting from nullified settings (seen rarely in Django) has been corrected.

Notes

This release of the Python agent fixes an issue with FastAPI instrumentation, as well as restricts gRPC to compatible versions.

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

Bug Fixes

• Fix FastAPI context propagation error

  A runtime instrumentation error stemming from context propagation in FastAPI has been fixed.

• Fix gRPC incompatibilities

  The version of gRPC has been pinned until compatiblity can be ensured with newer versions.

  gRPC recently enabled retries by default on channel connections, potentially causing a storm of requests and open threads to starve the host of resources, as well as strain our trace observers. This pin should alleviate these issues until retries can be properly configured.

Notes

This release of the Python agent fixes an issue with urllib recursion as well as an import error caused by non-ASCII characters in comments

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

Bug Fixes

• Fix urllib3 recursion regression

  Urllib3 recursion regression issue that was seen in Gevent has been fixed

• Fix import error caused by non-ASCII character in comments

  An import error caused by non-ASCII characters has been fixed to the correct quotation formatting
