Python agent release notesRSS

Notes

This release of the Python agent fixes a bug in the NewRelicContextFormatter where attributes were dropped from logs.

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 log attribute dropping in NewRelicContextFormatter
  • In v9.5.0, a bug in the NewRelicContextFormatter was introduced where message was added to the default set of keys to exclude. This caused extra attributes not in the default list to be dropped. This bug has 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.

See the New Relic Python agent EOL policy for information about agent releases and support dates.

Notes

This release of the Python agent no longer reports attributes with None values. It also attaches a transaction trace ID to the error traces even when distributed tracing is disabled.

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

• Remove reporting of attributes with None values

  • Previously, the agent recorded attributes with a value of None type as the string "None". The agent will no longer record user or agent attributes that have None type values.

Bug fixes

• Add transaction trace ID to the error traces even when distributed tracing is disabled
  • Previously, certain trace attributes in error traces such as stack traces were only visible in the UI if distributed tracing was enabled. Linking the transaction trace to error traces by including the transaction trace ID on the error traces allows the user to have access to the transaction trace attributes in the UI.

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.

Notes

This release of the Python agent fixes a bug when specifying processors in structlog, and updates the NewRelicLogForwardingHandler to support dictionary type logs and formatters.

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

• Support dictionary type logs in NewRelicLogForwardingHandler

  • Dictionary type log messages are now supported in NewRelicLogForwardingHandler when passed as the log message, or when a custom formatter returns a dictionary.
  • The key message will be extracted if available and treated as the log message, and any other items will be considered context data attributes and prefixed with message..
    • These attributes are subject to the same filtering rules as other context data. The message. prefix is not considered when filtering attributes from logs.
    • To report these attributes, enable context data forwarding and optionally configure include and exclude rules to filter the allowed attributes.

• Support logging formatters in NewRelicLogForwardingHandler

  • Logging formatters added with setFormatter() are now supported, and may return a string or dicitionary log message type to be forwarded to New Relic.

Bug fixes

• Fix a bug when specifying processors in structlog
  • Previously, there was a bug in the structlog instrumentation where processors was assumed to be list type. Now the instrumentation supports processors of all iterable types.

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.

Notes

This release of the Python agent adds context data attributes to logs, support for dictionary type log messages, adds attribute support to record_log_event API, and obfuscates logged license keys and user API keys.

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 context data attributes to logs

  • Context data available from logging frameworks can now be recorded as attributes on logs. These attributes are prefixed with context., which is not considered when filtering attributes from logs.
  • Context data may include extras, dictionary message attributes, and attributes provided by logging frameworks.
  • To report these attributes, enable context data forwarding and optionally configure include and exclude rules to filter the allowed attributes.

• Add support for dictionary type log messages

  • Dictionary type log messages are now supported for logging frameworks which support dictionary type log messages (including the builtin logging module and structlog).
  • The key message will be extracted if available and treated as the log message, and any other items will be considered context data attributes and prefixed with message.. These attributes are subject to the same filtering rules as other context data.

• Add attribute support to record_log_event API

  • The record_log_event API now allows passing context data in using the optional attributes keyword argument, and allows the message argument to be a dictionary as described above.

• Obfuscate license keys and user API keys in logs

  • The agent now obfuscates all instances of license keys or user API keys in agent logs and audit logs.

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.

Notes

This release of the Python agent adds support for nonced content security policies for browser agent injection, adds new wheels for Python 3.12 and musl Linux systems such as Alpine, deprecates the ObjectWrapper and get_browser_timing_footer APIs, fixes a crash with Kafka instrumentation when using distributed tracing, and removes a case sensitive header check in ASGIBrowserMiddleware.

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

Deprecations

• Deprecated newrelic.agent.ObjectWrapper API

  • Removes custom newrelic.agent.ObjectWrapper implementation and instead creates a pass through to wrapt.FunctionWrapper.

• Deprecated get_browser_timing_footer API

  • Previously get_browser_timing_footer was an API that would be used to supply information to the browser agent loaded by get_browser_timing_header.
  • This step is now included in get_browser_timing_header, making get_browser_timing_footer obsolete. This function now returns an empty string to avoid breaking existing applications.

New features

• Added nonced content security policies (CSPs) for browser agent injection

  • The browser agent injection API get_browser_timing_header has a new parameter nonce that takes a cryptographic nonce for use with content security policies. The nonce will be automatically inserted into the generated HTML.

• Added additional wheel options for Python 3.12 and musl Linux

  • Added pre-built binary wheel support for Python 3.12 as well as alternative wheels for musl-based Linux operating systems (such as Alpine).

• Added newrelic.agent.CallableObjectProxy to public APIs

  • Previously CallableObjectProxy was never exposed for general use with custom instrumentation, but was present in internal modules used by the agent.
  • This API has been added to newrelic.agent.CallableObjectProxy for general use.

Bug fixes

• Fixed a crash with kafka-python and confluent-kafka when using distributed tracing

  • Previously Kafka instrumentation packages would sometimes fail to generate distributed tracing headers and cause a crash. This has been fixed and distributed tracing headers should now generate correctly.

• Removed case sensitive header check in ASGIBrowserMiddleware

  • The agent previously only supported HTML insertion for headers that were lowercase in ASGI applications. The header check is now case insensitive in compliance with the ASGI specification.

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.
