v13.13.0 (2026-02-17)

Feature Release

With this release, we are making available our Node.js Hybrid Agent. The Node.js Hybrid Agent provides a future-proof observability solution with integrated support for OpenTelemetry Tracing, Metrics, and Logs APIs. Key enhancements like Span Links and Events on Spans are now available, ensuring seamless interoperability in mixed-mode environments. It is designed to bridge the gap for Node.js teams looking to adopt OpenTelemetry standards while maintaining backwards compatibility with their existing New Relic dashboards.

A full product announcement, and documentation for this feature, is coming soon. Please subscribe to our news releases to be kept up-to-date.
