Helm vs Sonarr: at a glance
What is Helm?
Helm 4 takes patches while Helm 3 winds down
Helm runs two trains: Helm 3.22.0 was the last Helm 3 minor, and Helm 4 carries active development. 4.3.0 brought concurrent status computation, ownership checks before uninstall and reproducible chart archives. 4.3.1 is a small patch that waits for CRDs to be established under the hook-only strategy.
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.

Helm 4 takes patches while Helm 3 winds down
◆ Current state
Helm runs two trains: Helm 3.22.0 was the last Helm 3 minor, and Helm 4 carries active development. 4.3.0 brought concurrent status computation, ownership checks before uninstall and reproducible chart archives. 4.3.1 is a small patch that waits for CRDs to be established under the hook-only strategy.
◆ Where it's heading
Helm 4 is putting its effort into correctness for GitOps and CI pipelines at scale: uninstall safety, status speed, CRD ordering. Helm 3 is in patch-only mode, and its releases now mostly carry dependency and security bumps.
◆ Prediction
Expect further 4.3.x patches focused on install and upgrade ordering edge cases, and only security or dependency patches on the 3.22 line. Feature work will likely wait for the next Helm 4 minor.
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.
