NetBird vs Sonarr: at a glance
What is NetBird?
NetBird's v0.81 reaches rc.3 with nothing left but cleanup.
NetBird is stabilizing v0.81. rc.1 merged certificate posture checks backed by PKCS#11 tokens and macOS keychains, per-target HTTP access actions in the reverse proxy, the unprivileged nblink forwarder, and UBI images for every server component. rc.2 and rc.3 carry only small management and infrastructure backports. A separate canary adds time hysteresis so clients stop flapping between HA routing peers that report the same metric.
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.

NetBird
5.0INFRA · APIS
NetBird's v0.81 reaches rc.3 with nothing left but cleanup.
◆ Current state
NetBird is stabilizing v0.81. rc.1 merged certificate posture checks backed by PKCS#11 tokens and macOS keychains, per-target HTTP access actions in the reverse proxy, the unprivileged nblink forwarder, and UBI images for every server component. rc.2 and rc.3 carry only small management and infrastructure backports. A separate canary adds time hysteresis so clients stop flapping between HA routing peers that report the same metric.
◆ Where it's heading
The project keeps moving from mesh VPN toward a zero-trust access platform. It now checks device identity at the endpoint and applies HTTP-level policy per proxy target, not just network reachability. Alongside that, routing and relay work keep targeting stability under failover, which matters most for the enterprise deployments the Red Hat UBI images aim at.
◆ Prediction
Three shrinking release candidates point to v0.81.0 final shortly, with certificate posture checks as the headline. Whether the route hysteresis and daemon socket restrictions make v0.81 or land in v0.82 is unclear from the entries.
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.
