Skipper vs Sonarr: at a glance
What is Skipper?
Skipper's latest six tags are test and dependency work; the proxy itself is unchanged.
Skipper tags a release for nearly every merge. The newest, v0.28.36, consolidates scattered test-certificate infrastructure for mTLS, OAuth grant and proxy tests ahead of new TLS use cases. Before that came five dependency builds: govulncheck and osv-scanner fixes, 18 Go module bumps, a CI action and two fuzzing images. The last proxy changes, about a week ago, were a fade-in path that stops copying endpoints per request and a fix for stale-while-revalidate cache refresh.
What is Sonarr?
Sonarr's 5.0 builds now block executables and risky files by default.
Sonarr is iterating on 5.0 builds while 4.0.x receives only occasional patches. The 5.0.0.2569 rollup removed Basic Auth, defunct IMDb lists and Kometa metadata and moved screens to React Query. Three days later, 5.0.0.2608 fails executables and potentially dangerous files by default for most indexers, fails torrents whose rejected extensions qBittorrent skipped, and addresses early v5 UI feedback. The feed still picks up Weblate translation tags from Prowlarr and Radarr that contain no Sonarr changes.

Skipper's latest six tags are test and dependency work; the proxy itself is unchanged.
◆ Current state
Skipper tags a release for nearly every merge. The newest, v0.28.36, consolidates scattered test-certificate infrastructure for mTLS, OAuth grant and proxy tests ahead of new TLS use cases. Before that came five dependency builds: govulncheck and osv-scanner fixes, 18 Go module bumps, a CI action and two fuzzing images. The last proxy changes, about a week ago, were a fade-in path that stops copying endpoints per request and a fix for stale-while-revalidate cache refresh.
◆ Where it's heading
Skipper keeps taking on edge responsibilities, identity via token exchange and response caching, while tightening the hot path. The certificate refactor explicitly prepares for more TLS cases, with a reference to a 'swarm TLS' path, which suggests mTLS between Skipper instances is next.
◆ Prediction
Expect a TLS-related feature, likely around swarm or instance-to-instance TLS, to build on the unified certificate test setup. Until then, more Dependabot tags and cache or proxy fixes.
Sonarr
5.0INFRA · APIS
Sonarr's 5.0 builds now block executables and risky files by default.
◆ Current state
Sonarr is iterating on 5.0 builds while 4.0.x receives only occasional patches. The 5.0.0.2569 rollup removed Basic Auth, defunct IMDb lists and Kometa metadata and moved screens to React Query. Three days later, 5.0.0.2608 fails executables and potentially dangerous files by default for most indexers, fails torrents whose rejected extensions qBittorrent skipped, and addresses early v5 UI feedback. The feed still picks up Weblate translation tags from Prowlarr and Radarr that contain no Sonarr changes.
◆ Where it's heading
5.0 is shaping up as a hardening release: legacy auth and integrations removed, and safer handling of what downloads are allowed to land. The quick follow-up build responding to UI feedback suggests 5.0 is in active testing with users rather than a long-lived branch.
◆ Prediction
Expect more 5.0.0 builds tightening download safety and polishing the new UI; when 5.0 replaces 4.x as the default track is not clear from these entries.
