Traefik v3.6.11 released on 19-03-2026
Traefik v3.6.11 is out now. It adds OpenTelemetry‑conformant trace context attributes to access logs and includes a number of Kubernetes, HTTP/TLS and authentication fixes that improve interoperability and resilience for users sending logs to OTEL-compatible tracing pipelines or running Traefik on Kubernetes.
See the Traefik GitHub release for full details and downloads.
What’s in this release
- Adds OTel-conformant trace context attributes to access logs so tracing fields exported in logs match OpenTelemetry expectations (PR #12801).
- Fixes Kubernetes integration issues: incorrect hostname matching between GatewayAPI listeners and routes, a corrected Ingress router rule, and proxy-ssl-verify annotation handling for ingress-nginx (PRs #12599, #12808, #12825).
- HTTP/TLS and auth improvements: maxResponseBodySize configuration on the HTTP provider, support for fragmented TLS ClientHello messages, and constant-time basic auth checks to reduce timing-attack risk (PRs #12788, #12787, #12803).
