Traefik v3.6.13 released on 07-04-2026
Traefik v3.6.13 is out now. Operators and users get a middleware compression bug fix plus a set of documentation and configuration clarifications for Docker, service discovery scope and Kubernetes/ingress-nginx integration.
See the Traefik GitHub release notes and documentation for full details and the individual pull requests that accompany this patch.
What’s in this release
- Bumped middleware dependency github.com/klauspost/compress to v1.18.4 and fixed the TestNegotiation issue to address content negotiation/compression behaviour.
- Documentation fixes: corrected the docker-compose.yaml location on the Docker setup page and added missing redirects for Getting Started and deleted pages.
- Clarified how to restrict the scope of service discovery across Docker, Consul, ECS and Kubernetes, and added Kubernetes/ingress-nginx guidance including OVHcloud (OpenStack Octavia) to Cloud-Specific IP Management and a fix for the default of http.sanitizePath.
Upgrade notes
- No breaking changes reported. Operators should verify middleware compression/content-negotiation behaviour after upgrading; see PR #12937 on the Traefik GitHub for the details of the dependency bump.
- If you need to roll back, revert to your previous 3.6.x deployment using your normal upgrade tooling or release process.
