This release of the Python agent makes the following changes: - Removes support for Python 3.7 - Removes and or deprecates various APIs and settings - Deprecates [aioredis](https://pypi.org/project/aioredis/) instrumentation - Raises the minimum supported version of `setuptools` and `setuptools_scm` - Adds new instrumentation for [AutoGen](https://github.com/microsoft/autogen) - Adds new instrumentation for [Pyzeebe](https://pypi.org/project/pyzeebe/) - Adds new MCP (Model Context Protocol) named spans - Fixes a crash in psycopg - Ensures MCP spans are only recorded when AI monitoring is enabled Install the agent using `easy_install/pip/distribute` via the [Python Package Index](https://pypi.python.org/pypi/newrelic) or download it directly from the [New Relic download site](https://download.newrelic.com/python_agent/release). ## Removed features - Removes support for Python 3.7 - Python 3.7 was EOL'd June 27, 2023. The Python agent has dropped support for it. - Removes various deprecated APIs - The following APIs have been removed: | Legacy API | Replacement API | | ----------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `accept_distributed_trace_payload` | [`accept_distributed_trace_headers`](https://docs.newrelic.com/docs/agents/python-agent/python-agent-api/acceptdistributedtraceheaders-python-agent-api) | | `add_custom_parameter` | [`add_custom_attribute`](https://docs.newrelic.com/docs/apm/agents/python-agent/python-agent-api/addcustomattribute-python-agent-api) | | `add_custom_parameters` | [`add_custom_attributes`](https://docs.newrelic.com/docs/apm/agents/python-agent/python-agent-api/addcustomattributes-python-agent-api) | | `create_distributed_trace_payload` | [`insert_distributed_trace_headers`](https://docs.newrelic.com/docs/apm/agents/python-agent/python-agent-api/insertdistributedtraceheaders-python-agent-api) | | `get_browser_timing_footer` | The functionality of this has been wrapped into [`get_browser_timing_header()`](https://docs.newrelic.com/docs/apm/agents/python-agent/python-agent-api/getbrowsertimingheader-python-agent-api) | | `record_exception` | [`notice_error()`](https://docs.newrelic.com/docs/agents/python-agent/python-agent-api/notice_error) | | `NewRelicLogHandler` | `NewRelicLogForwardingHandler` | | `lambda_handler` & `LambdaHandlerWrapper` | These APIs have moved to the [`newrelic-lambda`](https://docs.newrelic.com/docs/serverless-function-monitoring/aws-lambda-monitoring/instrument-lambda-function/sdk-based-instrumentation/#python) package. | - Removes various deprecated settings - The following settings have been removed: | Legacy Setting | Replacement Setting | | --------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `transaction_tracer.capture_attributes` | [`transaction_tracer.attributes.enabled`](https://docs.newrelic.com/docs/apm/agents/python-agent/configuration/python-agent-configuration#cfg-tt-attributes-enabled) | | `error_collector.capture_attributes` | [`error_collector.attributes.enabled`](https://docs.newrelic.com/docs/apm/agents/python-agent/configuration/python-agent-configuration#cfg-error-attributes-enabled) | | `browser_monitoring.capture_attributes` | [`browser_monitoring.attributes.enabled`](https://docs.newrelic.com/docs/apm/agents/python-agent/configuration/python-agent-configuration#cfg-browser-attributes-enabled) | | `analytics_events.enabled` | [`transaction_events.enabled`](https://docs.newrelic.com/docs/apm/agents/python-agent/configuration/python-agent-configuration#transaction-events-enabled) | | `analytics_events.capture_attributes` | [`transaction_events.attributes.enabled`](https://docs.newrelic.com/docs/apm/agents/python-agent/configuration/python-agent-configuration#cfg-events-attributes-enabled) | | `error_collector.ignore_errors` | [`error_collector.ignore_classes`](https://docs.newrelic.com/docs/apm/agents/python-agent/configuration/python-agent-configuration#error-ignore) | | `strip_exception_messages.whitelist` | [`strip_exception_messages.allowlist`](https://docs.newrelic.com/docs/apm/agents/python-agent/configuration/python-agent-configuration#strip_exception_messages_allowlist) | | `ssl` | This is now hardcoded to `true` so it has been removed as a setting option. | | `ignored_params` | Use `newrelic.attributes.exclude = request.parameters.{name}` instead. Add each request parameter key to the `newrelic.attributes.exclude` list, delimited by commas. Be sure to prepend the key with `request.parameters`. | | `agent_limits.merge_stats_maximum` | This is now completely ignored in favor of serverside config. | ## Deprecated features - Instrumentation for [aioredis](https://pypi.org/project/aioredis/) has been deprecated - The [aioredis](https://pypi.org/project/aioredis/) package has been deprecated in favor of [redis](https://pypi.org/project/redis/) which now includes the submodule `redis.asyncio`. As a result, the instrumentation for `aioredis` has also been deprecated. Please use the `redis` library instead. This instrumentation will be removed in a future release. - Deprecates some existing harvest settings to match other language agents - In order to be more consistent with the conventions of the other language agents, the following harvest settings are now deprecated: | Legacy Setting | Replacement Setting | | --------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `event_harvest_config.harvest_limits.analytic_event_data` | [`transaction_events.max_samples_stored`](https://docs.newrelic.com/docs/apm/agents/python-agent/configuration/python-agent-configuration#transaction-events-max-samples-stored) | | `event_harvest_config.harvest_limits.span_event_data` | [`span_events.max_samples_stored`](https://docs.newrelic.com/docs/apm/agents/python-agent/configuration/python-agent-configuration#cfg-tt-max-samples-stored) | | `event_harvest_config.harvest_limits.error_event_data` | [`error_collector.max_event_samples_stored`](https://docs.newrelic.com/docs/apm/agents/python-agent/configuration/python-agent-configuration#error-max-event-samples-stored) | | `event_harvest_config.harvest_limits.custom_event_data` | [`custom_insights_events.max_samples_stored`](https://docs.newrelic.com/docs/apm/agents/python-agent/configuration/python-agent-configuration#custom-insights-events-max-samples-stored) | | `event_harvest_config.harvest_limits.log_event_data` | [`application_logging.forwarding.max_samples_stored`](https://docs.newrelic.com/docs/apm/agents/python-agent/configuration/python-agent-configuration#application-logging-forwarding-max-samples-stored) | This is a revert of a previous change that renamed these settings from `*.max_samples_stored` to the `event_harvest_config.harvest_limits.*` form. This decision has been reversed, and the original settings named have been restored to match the other language agents who did not change these settings names. The deprecated settings will continue to work for now, but they will be removed in a future release. - Deprecates configuration of the agent through the WSGI environ dictionary - The following settings which were previously possible to configure through the WSGI environ dictionary are now deprecated. Please configure these settings through environment variables or the config file. - `newrelic.set_background_task` - `newrelic.suppress_apdex_metric` - `newrelic.suppress_transaction_trace` - `newrelic.capture_request_params` - `newrelic.disable_browser_autorum` - Deprecates support for building the agent with `setuptools<61.2` or `setuptools_scm<6.4` - The minimum supported versions of `setuptools` and `setuptools_scm` have been increased to `61.2` and `6.4` respectively. This is to support the use of `pyproject.toml` for configuring the package metadata and building instructions. The agent can now be built with more modern build tools which will no longer log warnings about the lack of a `pyproject.toml` file. - This change adds new version attributes to the packages, `newrelic.__version__` and `newrelic.__version_tuple__`, which can be used to programmatically check the version of the agent at runtime. ## New features - Adds new instrumentation for [AutoGen](https://github.com/microsoft/autogen) - Adds instrumentation (named spans and custom `Llm` events) for agents and tools in [AutoGen](https://github.com/microsoft/autogen) - Adds new instrumentation for [Pyzeebe](https://pypi.org/project/pyzeebe/) - Adds automatic instrumentation and framework-specific agent attributes for [Pyzeebe](https://pypi.org/project/pyzeebe/) - Adds new MCP (Model Context Protocol) named spans - Adds new named spans for MCP (Model Context Protocol) tool calls made via tool manager to support Streamable HTTP ## Bug fixes - Fixes a crash in `psycopg>=3.2.0` when calling `as_string()` - Fixes an issue in `psycopg>=3.2.0` where the `as_string()` method no longer required arguments, causing a potential crash. This has been fixed, and both signatures of this method are supported. - Ensures MCP (Model Context Protocol) spans are only recorded when AI monitoring is enabled - Ensures MCP (Model Context Protocol) spans are only recorded when the setting `ai_monitoring.enabled` is enabled. ## 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.
