What is Skipper?

One pull request per version tag, and most of them are dependency bumps.

Skipper cuts a release for essentially every merged pull request — six tags between 27 July and 7 August, each containing a single change. Two of the six are Dependabot bumps to CI actions and a fuzzing base image, two are test-only adjustments, and one fixes an error type assertion. Every entry carries the same boilerplate pointing at the multiarch image in GitHub's registry.

What is Inspektor Gadget?

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.

Skipper vs Inspektor Gadget: editorial side-by-side

S
Skipper
INFRA · APIS
5.0

One pull request per version tag, and most of them are dependency bumps.

◆ Current state

Skipper cuts a release for essentially every merged pull request — six tags between 27 July and 7 August, each containing a single change. Two of the six are Dependabot bumps to CI actions and a fuzzing base image, two are test-only adjustments, and one fixes an error type assertion. Every entry carries the same boilerplate pointing at the multiarch image in GitHub's registry.

◆ Where it's heading

The visible work is maintenance of an already-stable proxy rather than feature development. What the test changes hint at is where the correctness concerns sit: an OPA policy test updated to explicitly deny truncated request bodies, because oversized JSON cannot be fully parsed and a policy that ignores input.truncated_body can be bypassed. That is authorization-under-load hardening, and it is the most interesting thing in the window even though it landed as a test.

◆ Prediction

The per-PR tagging rhythm will continue producing several versions a week regardless of change size. Readers tracking this product should expect the meaningful changes to be a small minority of the tags.

6.3

The eBPF observability tool just started reaching for the GPU.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.
