rsyslog vs Sonarr: at a glance
What is rsyslog?
rsyslog keeps adding cloud outputs, with Kinesis in October after CloudWatch in August.
rsyslog publishes a scheduled-stable snapshot every two months. April added YAML configuration and native OpenTelemetry protobuf output, June an Elastic Beats input and TCP compression, and August an imkubernetes input that tails pod and container logs, segmented disk-assisted queues and a CloudWatch Logs output. The October 8.2610.0 snapshot adds an Amazon Kinesis Data Streams output and an experimental producer-local queue.
What is Sonarr?
Sonarr 5.0 swaps its interactive search table for cards and trims what counts as advanced.
Sonarr keeps publishing 5.0 test builds every few days. Build 2907 replaces the interactive search table with cards, marks advanced settings and moves fewer settings behind that label, and cuts duplicate requests on load. Build 2870 added TMDb import lists and a Multi-Season Pack release type. Accessibility work continues, with more context on System page and Manual Import buttons.

rsyslog keeps adding cloud outputs, with Kinesis in October after CloudWatch in August.
◆ Current state
rsyslog publishes a scheduled-stable snapshot every two months. April added YAML configuration and native OpenTelemetry protobuf output, June an Elastic Beats input and TCP compression, and August an imkubernetes input that tails pod and container logs, segmented disk-assisted queues and a CloudWatch Logs output. The October 8.2610.0 snapshot adds an Amazon Kinesis Data Streams output and an experimental producer-local queue.
◆ Where it's heading
Across 2026 rsyslog has moved from a host syslog daemon toward a container and cloud log shipper, adding inputs for Kubernetes and outputs for AWS services each cycle. Queueing is the other active area.
◆ Prediction
The next scheduled-stable snapshot is due in December on the two-month rhythm; which outputs it adds is unclear from the feed.
Sonarr
5.0INFRA · APIS
Sonarr 5.0 swaps its interactive search table for cards and trims what counts as advanced.
◆ Current state
Sonarr keeps publishing 5.0 test builds every few days. Build 2907 replaces the interactive search table with cards, marks advanced settings and moves fewer settings behind that label, and cuts duplicate requests on load. Build 2870 added TMDb import lists and a Multi-Season Pack release type. Accessibility work continues, with more context on System page and Manual Import buttons.
◆ Where it's heading
5.0 is still mixing contributor features with interface rework and accessibility polish. Performance work now joins it, with cache updates, import list sync and load-time requests all optimized in one build. Basic Auth removal and file safety defaults set its stricter baseline.
◆ Prediction
Expect more interface and accessibility fixes before 5.0 reaches the stable channel. Larger changes are still landing in test builds, so the timing of that release remains unclear.
