- Updated
getBrowserTimingHeaderto allow the browser agent to be generated even when not in a transaction by addingallowTransactionlessInjectionto function options.allowTransactionlessInjectionis a boolean option, and when set totrue, will allow injection of the browser agent when not in a transaction. This is intended to be used in frameworks that build Static Site Generation(SSG). Note that if you're using this option, you may need to wait until the Node agent has established a connection before callinggetBrowserTimingHeader. To wait until the agent is connected, you can add the following check to your code:
if (!newrelic.agent.collector.isConnected()) { await new Promise((resolve) => { newrelic.agent.on('connected', resolve) })}Support statement:

Notes
Added a check to the code level metrics utility to ensure filePath was set before adding the
code.*attributes.Updated to latest version of
@newrelic/test-utilities.Fixed issue where listing of dependencies and packages from symlinked nested directories created an infinite loop which caused the agent to never connect.

Notes
Reintroduced throttling during reading of instrumented application's dependency tree during startup, to prevent EMFILE issues.
Improved Restify support
- Added a new test stanza to run restify >=10 on Node 18.
- Update our versioned tests to support Restify 9.0.0.
Laid foundation for supporting Code Level Metrics via CodeStream. Note that this integration is not fully finished and should not be used.
Improved the readability and maintainability of agent by reducing the Cognitive Complexity of various aspects of the agent.
Added
newrelic.noticeError()example to our API docs.Upgraded @grpc/grpc-js from 1.6.9 to 1.7.3.
Upgraded @grpc/proto-loader from 0.6.13 to 0.7.3.
Removed async from benchmark tests, fixed failing benchmark suites, and removed deprecated suite.

Notes
- Added new configuration option,
grpc.ignore_status_codes, which can be used to select nonzero gRPC status codes to ignore and not report as errors.

Notes
Dropped support for
vision, and instead only instrument@hapi/vision.Updated configuration system to automatically create an environment variable mapping for a new config value.
- It will follow a convention of
NEW_RELIC_PATH_TO_CONFIG_KEY. - For example if there is a new configuration option of
config.nested.object_path.enabledthe env var would beNEW_RELIC_NESTED_OBJECT_PATH.ENABLED.
- It will follow a convention of
Removed
transaction_tracer.hide_internalsconfiguration. All of the internal configuration is now handled by Javascript symbols instead of non-enumerable properties, so there is no longer a performance penalty, as symbols are already hidden by default.

Notes
Increased the default limit of custom events from 1,000 events per minute to 3,000 events per minute. In the scenario that custom events were being limited, this change will allow more custom events to be sent to New Relic. There is also a new configurable maximum limit of 100,000 events per minute. To change the limits, see the docs for custom_insights_events. To learn more about the change and how to determine if custom events are being dropped, see our Explorers Hub post.
Updated CI process to include collection of code coverage statistics.
Added a [doc about our current feature flags)(https://github.com/newrelic/node-newrelic/blob/main/documentation/feature-flags.md).

- New Relic recommends that you upgrade the agent regularly to ensure that you're getting the latest features and performance benefits. Additionally, older releases will no longer be supported when they reach end-of-life.
Notes
Removed legacy agent async context propagation. The default behavior is now what was behind the
feature_flag.new_promise_tracking. You can read more about the difference here.Fixed an issue with the ES Module loader that properly registers instrumentation when the file path included url encoded characters.
Added an API for enqueuing application logs for forwarding
newrelic.recordLogEvent({ message: 'hello world', level: 'info' })`Note: If you're including a serialized error make sure it's on the
errorkey of the log event:const error = new Error('testing errors');newrelic.recordLogEvent({ message: 'error example', level: 'error', error })Fixed
cassandra-driverinstrumentation to properly set instance details on query segments/spans.Added a new context manager that leverages AsyncLocalStorage for async context propagation.
- This will be available via a feature flag
config.feature_flag.async_local_context - Alternatively you can set the environment variable of
NEW_RELIC_FEATURE_FLAG_ASYNC_LOCAL_CONTEXT=1 - By enabling this feature flag it should make the agent use less memory and CPU.
- This will be available via a feature flag
