Traefik v3.7.10 released on 31-07-2026
Traefik v3.7.10 is out now. It benefits operators using automatic Let’s Encrypt issuance, Kubernetes Gateway API or CRD configurations, auth middlewares and Datadog tracing by refreshing ACME and core dependencies and fixing several routing and authentication issues.
See the Traefik GitHub release page for the full notes and any additional upgrade guidance.
What’s in this release
- Bumps go-acme/lego to v5.3.1 and updates golang.org/x/text to v0.40.0 and golang.org/x/net to v0.57.0 — refreshes ACME client code and underlying libraries, which may include bugfixes and minor behavioural changes.
- Fixes router name collisions in the Kubernetes Gateway API provider and bumps sigs.k8s.io/gateway-api to v1.6.1; also fixes cross-namespace service reference checks in the Kubernetes CRD provider to prevent routing conflicts and validation issues.
- Addresses an auth singleflight key collision that could affect concurrent requests, bumps middleware dependency klauspost/compress to v1.18.7, and updates Datadog tracing integration with github.com/DataDog/dd-trace-go/v2 to 2.8.1.
Upgrade notes
- No explicit breaking changes are listed; operators using automatic Let’s Encrypt issuance should plan the upgrade and run smoke tests to validate ACME issuance and certificate renewal.
- If you need to roll back, return to your previously running Traefik release and re-validate routing, authentication and tracing behaviour in your environment.
Share your experience after upgrading — particularly if you run Gateway API or CRD configs, auth middlewares under load, or Datadog tracing so others know whether the fixes behave as expected.
