Sonarr vs Traefik: at a glance
What is Sonarr?
Sonarr 5.0 swaps its interactive search table for cards and trims what counts as advanced.
Sonarr keeps publishing 5.0 test builds every few days. Build 2907 replaces the interactive search table with cards, marks advanced settings and moves fewer settings behind that label, and cuts duplicate requests on load. Build 2870 added TMDb import lists and a Multi-Season Pack release type. Accessibility work continues, with more context on System page and Manual Import buttons.
What is Traefik?
Traefik v2.11 ships three CVEs and Kubernetes CRD collision fixes in maintenance-mode patch cycle.
Traefik v2.11.x is in long-term stable maintenance, releasing bi-weekly patches. Recent work is entirely security-focused (three CVEs in the September 7 release alone: GHSA-qqjf-53cj-pwvv, GHSA-f52w-8j3h-j724, GHSA-w4v4-9rw7-5326) and reliability-focused (Kubernetes CRD name collision prevention, HTTP/3 timeout handling, CONNECT tunnel fixes). No net-new features are arriving on this branch — all active development is in v3.x.

Sonarr
5.0INFRA · APIS
Sonarr 5.0 swaps its interactive search table for cards and trims what counts as advanced.
◆ Current state
Sonarr keeps publishing 5.0 test builds every few days. Build 2907 replaces the interactive search table with cards, marks advanced settings and moves fewer settings behind that label, and cuts duplicate requests on load. Build 2870 added TMDb import lists and a Multi-Season Pack release type. Accessibility work continues, with more context on System page and Manual Import buttons.
◆ Where it's heading
5.0 is still mixing contributor features with interface rework and accessibility polish. Performance work now joins it, with cache updates, import list sync and load-time requests all optimized in one build. Basic Auth removal and file safety defaults set its stricter baseline.
◆ Prediction
Expect more interface and accessibility fixes before 5.0 reaches the stable channel. Larger changes are still landing in test builds, so the timing of that release remains unclear.
Traefik
5.0INFRA · APIS
Traefik v2.11 ships three CVEs and Kubernetes CRD collision fixes in maintenance-mode patch cycle.
◆ Current state
Traefik v2.11.x is in long-term stable maintenance, releasing bi-weekly patches. Recent work is entirely security-focused (three CVEs in the September 7 release alone: GHSA-qqjf-53cj-pwvv, GHSA-f52w-8j3h-j724, GHSA-w4v4-9rw7-5326) and reliability-focused (Kubernetes CRD name collision prevention, HTTP/3 timeout handling, CONNECT tunnel fixes). No net-new features are arriving on this branch — all active development is in v3.x.
◆ Where it's heading
The v2.11 branch will continue receiving CVE backports and stability fixes for the foreseeable future, but the feature roadmap has moved to Traefik v3. The Kubernetes CRD naming collision fixes in v2.11.55 indicate active operator usage surfacing edge cases in large cluster deployments. The security frequency (5+ CVEs in 60 days) suggests either coordinated disclosure or active vulnerability research against this codebase.
◆ Prediction
CVE patches will continue arriving at the current pace. Operators needing new capabilities — improved HTTP/3, modern middleware, v3 provider model — will need to migrate; the v2.11 branch offers no path to those features.
