Jackett
A daily indexer-repair treadmill: Jackett patches tracker definitions as fast as trackers change.
A side-by-side editorial comparison of Inspektor Gadget and rsyslog — release velocity, themes, recent moves, and the top alternatives to consider.
The eBPF observability tool just started reaching for the GPU.
Inspektor Gadget ships a feature release roughly monthly with bugfix releases in between, and the recent line has been steady kernel-side expansion: new gadgets, more eBPF program types, better stack symbolization. v0.55.0 breaks that pattern by adding initial GPU telemetry — a userspace daemon called gpu-ebpf-bridge that publishes GPU data through pinned BPF maps so gadgets can consume it. The rest of the release is the usual widening of eBPF surface plus stability work for high-churn nodes.
The syslog daemon is quietly becoming an OpenTelemetry-era pipeline, YAML config and all.
rsyslog ships bi-monthly scheduled-stable snapshots of its daily-stable branch, and the last two carried real capability rather than upkeep. April added YAML as an alternative configuration format, an Azure Monitor output, API key authentication for imhttp, and native protobuf encoding for omotel over HTTP. June followed with an Elastic Beats and Lumberjack input, a POSIX FIFO input, experimental TCP stream compression between omfwd and imtcp, and shared per-source ratelimit policy.

Two directions run in parallel. The kernel-side surface keeps growing — SockOps, SkSKB and SkMsg program types, map pinning, non-destructive map iteration, OTel and Python stack symbolization — which makes the tool a more general eBPF runtime rather than a fixed set of gadgets. Meanwhile the output side is becoming opinionated about ecosystems it serves: v0.54.0 taught advise_networkpolicy to emit Cilium NetworkPolicy resources alongside Kubernetes ones. GPU telemetry extends the first direction past the boundary eBPF normally stops at.
The GPU work is explicitly described as an initial design laying groundwork, so expect the next releases to build actual gadgets on top of the bridge rather than to expand it further; the pinned-map plumbing added in the same release is what those gadgets would consume.

Two moves are reshaping what this product is. The configuration story is opening up — RainerScript, rsyslog's bespoke and long-criticized config language, now has a YAML alternative while gaining new helpers of its own. And the transport story is converging on the modern observability stack: native protobuf for OpenTelemetry output, a cloud vendor sink, Beats and Lumberjack ingestion. Underneath both runs continuous defensive hardening across parsers, inputs, outputs, queues and TLS, mentioned in both releases.
Expect the YAML configuration path to broaden from alternative to fully supported, and TCP stream compression to move from experimental to stable, since both are flagged as partial in the releases that introduced them.
