What is Hatchet?

Hatchet is shipping engine patches almost daily as it opens the scheduler to outside operators.

Hatchet is a task orchestration engine with durable execution, DAGs, cron and rate limits, shipped as a fast-moving open-source release train. In three days it cut seven engine releases, most of them narrow fixes to the DAG operator, durable waits, error passthrough and the cron ticker. The Python SDK keeps pace with flow-control features.

What is Sonarr?

Sonarr 5.0 builds add Trakt Smart Lists, OIDC Remember Me and more accessibility fixes.

Sonarr is publishing 5.0 test builds every few days. Recent ones added a Trakt Smart List import, an option to pass seed time to qBittorrent as an inactive-seeding limit, Remember Me for OIDC login and lower-memory media info migration. Accessibility work continues, with screen-reader feedback for form errors, named icon-only controls and an accessible Calendar.

INFRA · APIS
5.0

Hatchet is shipping engine patches almost daily as it opens the scheduler to outside operators.

◆ Current state

Hatchet is a task orchestration engine with durable execution, DAGs, cron and rate limits, shipped as a fast-moving open-source release train. In three days it cut seven engine releases, most of them narrow fixes to the DAG operator, durable waits, error passthrough and the cron ticker. The Python SDK keeps pace with flow-control features.

◆ Where it's heading

The 0.113.0 serverless operator, a gRPC service that lets operators run outside the engine, set the direction: Hatchet is turning its scheduler into a platform that external runtimes plug into. The patches since then harden that path, especially durable streams and DAG output handling, and add finer flow control such as pausing rate-limited queues.

◆ Prediction

Expect more durable-stream and operator fixes in the 0.113–0.114 line, followed by SDK support that makes out-of-process operators usable without hand-written gRPC.

5.0

Sonarr 5.0 builds add Trakt Smart Lists, OIDC Remember Me and more accessibility fixes.

◆ Current state

Sonarr is publishing 5.0 test builds every few days. Recent ones added a Trakt Smart List import, an option to pass seed time to qBittorrent as an inactive-seeding limit, Remember Me for OIDC login and lower-memory media info migration. Accessibility work continues, with screen-reader feedback for form errors, named icon-only controls and an accessible Calendar.

◆ Where it's heading

5.0 is in a polish phase: each build mixes small features from contributors with accessibility and UI fixes, after the earlier builds removed Basic Auth and tightened file safety. The pace suggests the team is converging on a stable 5.0.

◆ Prediction

Expect more accessibility and migration fixes before 5.0 reaches the stable channel; new large features look unlikely this late.
