ESPHome 2026.9.0 ships template climate component, OTA encryption with API key, and ESP-NOW for ESP32-P4
A side-by-side editorial comparison of Sonarr and Jackett — release velocity, themes, recent moves, and the top alternatives to consider.
Sonarr 4.0.x ships steady patch maintenance with no feature moves this cycle
Sonarr's 4.0.19.x and 4.0.20.x releases are nearly pure maintenance — the majority of entries are changelog-link-only patches with no documented user-facing changes. The one visible user-facing addition in this window is Jellyfin/Emby connection testing and a new Jellyfin auth header in v4.0.19.2995, keeping pace with upstream media server API changes.
Jackett in pure tracker-maintenance mode, daily domain and category updates only
Jackett ships automated daily builds that consist almost entirely of tracker-library upkeep: domain alternatives, broken selectors, new categories for individual sites. The core indexer-proxy architecture is stable and unchanged. The only user-visible improvement in this window is hiding the API key on the dashboard.

Sonarr is in maintenance mode for its 4.0.x branch. Tracker and media server compatibility updates are the steady-state output, with no signal of a major capability expansion or version bump. The Jellyfin auth header update confirms the team is responding to upstream API changes rather than driving new feature development.
Continued patch maintenance for tracker and media server compatibility. A 4.1.x release would be the meaningful signal to watch, but nothing in the entries suggests it is imminent.

The core indexer-proxy architecture is stable and unchanged. The only user-visible improvement in this window is hiding the API key on the dashboard.
The last 10 entries show no feature development — every commit is tracker registration data. Jackett's trajectory is entirely reactive to the torrent ecosystem: trackers move domains, change engines, and die; Jackett follows. There is no observable product initiative in this window.
The entries don't support a confident prediction about new feature direction. Daily tracker maintenance will continue as the primary output; any substantive change would come from outside this pattern.
