n8n n8n@2.40.7 released on 25-09-2026
n8n n8n@2.40.7 is out now. It fixes an observability bug so project-level span attributes are propagated to individual node spans, restoring project context on node-level traces and improving trace correlation and debugging.
See the release on GitHub for full details and the compare view: compare changes.
What’s in this release
- Propagate project span attributes to node spans (fixes issue #39457; commit 59fccb6).
- Node-level spans now retain project context, improving trace correlation, debugging and telemetry completeness across workflows.
- No functional workflow changes — this is an internal tracing/observability fix only.
Upgrade notes
- Non-breaking: update to n8n@2.40.7 (Docker image or package), restart n8n instances and validate tracing by running workflows and inspecting spans in your tracing backend (OpenTelemetry/Jaeger/Zipkin).
- If you see environment-specific issues while investigating traces, roll back to 2.40.6.
