Grype vs Skipper: at a glance
What is Grype?
Grype widens distro accuracy while each release clears its own dependency advisories.
Grype's autumn releases stay on matching accuracy. v0.121.0 carries AlmaLinux fix dates onto replaced RHEL matches and finds GitHub Swift advisories it previously missed, v0.120.0 marks SLES as a comprehensive distro and stores NVD SSVC decision points, and v0.119.0 exposes distro-fixed dropped matches through --show-suppressed. Each minor also carries a large dependency sweep, with v0.121.0 remediating five golang.org/x/net advisories.
What is Skipper?
Skipper now serves zone-filtered routes only when its own ingress is balanced across zones.
Skipper, Zalando's HTTP router and Kubernetes ingress, tags a release for nearly every merge, so most entries are dependency bumps. The substantive ones this autumn are about zone-aware routing: v0.28.56 made routesrv recompress only zones whose routes changed, and v0.28.60 on November 2 serves zone-filtered routes only when skipper-ingress is balanced across zones, falling back to the global table otherwise.

Grype
5.0INFRA · APIS
Grype widens distro accuracy while each release clears its own dependency advisories.
◆ Current state
Grype's autumn releases stay on matching accuracy. v0.121.0 carries AlmaLinux fix dates onto replaced RHEL matches and finds GitHub Swift advisories it previously missed, v0.120.0 marks SLES as a comprehensive distro and stores NVD SSVC decision points, and v0.119.0 exposes distro-fixed dropped matches through --show-suppressed. Each minor also carries a large dependency sweep, with v0.121.0 remediating five golang.org/x/net advisories.
◆ Where it's heading
Accuracy remains the roadmap, and the work is increasingly about distro-specific truth: fix dates, extended support and comprehensive coverage. SSVC data in the database is the one new kind of signal, since it adds decision guidance beyond severity. Reachability has still not moved past Go in these notes.
◆ Prediction
SSVC decision points are stored but not yet described as a user-facing output, so surfacing them in results is the natural next step. These notes give no signal on a second reachability ecosystem.
Skipper
5.0INFRA · APIS
Skipper now serves zone-filtered routes only when its own ingress is balanced across zones.
◆ Current state
Skipper, Zalando's HTTP router and Kubernetes ingress, tags a release for nearly every merge, so most entries are dependency bumps. The substantive ones this autumn are about zone-aware routing: v0.28.56 made routesrv recompress only zones whose routes changed, and v0.28.60 on November 2 serves zone-filtered routes only when skipper-ingress is balanced across zones, falling back to the global table otherwise.
◆ Where it's heading
Zone-aware routing is being made safe for production, with guards against skew and fixes for a data race and silent misconfiguration. It currently works only in the routesrv mode, and the release notes say the direct Kubernetes mode needs the same filtering.
◆ Prediction
Expect zone filtering to be extended to the skipper-to-Kubernetes mode in a coming tag, as the v0.28.60 notes say is needed.
