## Notes

## 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](https://newrelic.com/blog)
to be kept up-to-date.
