authentik vs Sonarr: at a glance
What is authentik?
authentik spends its post-2026.8 cycle hardening the proxy and SCIM paths the Agent release leaned on.
authentik is four patches into the 2026.8 line, and 2026.8.4 is the largest yet: two dozen fixes concentrated in the proxy outpost, SCIM provisioning, and endpoint device lookup. The 2026.5 and 2026.2 branches are still receiving backports, so three release lines are live at once. No new capability has shipped since the 2026.8.0 Agent and Actors release in August.
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.

authentik spends its post-2026.8 cycle hardening the proxy and SCIM paths the Agent release leaned on.
◆ Current state
authentik is four patches into the 2026.8 line, and 2026.8.4 is the largest yet: two dozen fixes concentrated in the proxy outpost, SCIM provisioning, and endpoint device lookup. The 2026.5 and 2026.2 branches are still receiving backports, so three release lines are live at once. No new capability has shipped since the 2026.8.0 Agent and Actors release in August.
◆ Where it's heading
The fix pattern follows the surface 2026.8.0 opened: endpoint fact snapshots, device lookup, and machine-facing proxy behaviour are where the bugs are landing. SCIM conflict resolution and remote error reporting suggest provisioning into downstream apps is getting real production load. The project is consolidating the device-identity bet rather than extending it yet.
◆ Prediction
The entries do not show a 2026.9 or 2026.11 feature branch in release form yet, so the next visible move is likely another 2026.8.x patch; whether the Agent gains new capabilities in the next major is not clear from these notes.
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.
