newrelic 8.4.0

v8.4.0

on Node.js NPM

Deprecation Warning: Cross Application Tracing (CAT) has been deprecated and will be removed in a future major release. For applications that explicitly disable Distributed Tracing (DT) to leverage CAT, we recommend migrating to DT to avoid loss of cross-service visibility.

• Disables CAT by default. You must explicitly enable CAT along with turning off DT.
• Adds a deprecation warning when CAT is enabled and active (DT disabled).

Fixed issue with clearTimeout that could result in dropping parent segments or spans.

This bug resulted in some MongoDB calls being dropped from Transaction Traces and Distributed Traces (spans): #922.

Removed warnings from agent tests for no-var eslint rule.

Added support for Cassandra driver v4.0.0 and above.

Fixed issue where DT headers would not be processed by transaction-shim.handleCATHeaders() when CAT was explicitly disabled. This primarily impacts amqplib instrumentation.

Transitioned aws-lambda.test.js to use Tap over Mocha.

Removed warnings from agent for no-var eslint rule.

Refactored transaction-shim, http and http-outbound to use centralized CAT methods in util/cat

Replaced http-outbound test call to use example.com to avoid unpredictable connection resets.

Migrated sql query parser tests to tap

Added more API usage examples.

Added a README to the examples/ folder discussing how to use the examples.

Fixed message-shim test assertion to avoid flakiness based on precision differences(ms vs ns)

Applied new lint rules barring the use of var and preferring the use of const wherever possible.
