Node.js agent v5.3.0

New features

• Added span_events and transaction_segments attribute destinations.

  Span event and segment attributes can now be filtered using the same include/exclude config rules as other types. See agent attribute configuration for more details.

• Added metadata field to connect payload, for collecting NEW_RELIC_METADATA_-prefixed environment variables.

• Added DynamoDB to datastores.

• Added opaque option to datastore operation spec.

• Added Kubernetes utilization detection.

• Upgraded concat-stream and readable-stream to next major version.

  These modules had previously been held back due to support for Node <6. Since v5.0.0 we dropped that support thus enabling these updates.

• Added SQS as a supported messaging library name.

• Enabled tracking of callback via message-shim.recordConsume when no messageHandler provided.

Improvements

• Replaced make rules with npm scripts.

Bug fixes

• The agent will now consistently harvest in all response cases when in serverless mode.

  Previously, the agent's harvest was in a race with process suspension in the event of an uncaught exception, or responding without calling a callback. A synchronous harvesting process is now used to circumvent this racing issue.

• Fixed issue with socket connection errors causing the agent to stop attempting to connect at startup.

• Fixed opaque segment functionality for message-shim.recordProduce.

• Fixed opaque segment functionality for message-shim.recordConsume.
