What is Fission?

Fission's release feed carries only RC tags, and none of them say what shipped

Every entry here is a release candidate — v1.22.0-rc1 and rc2, v1.23.0-rc1, v1.25.0-rc1 — with no final release appearing between them, and the version sequence skips 1.24 entirely. The bodies are whatever the tagging commit said, so what reaches this feed is a dependabot bump, a CLI tool-version refresh, a codegen sync explicitly labelled as having no functional change, and one entry that is nothing but links to an external release-highlights page. The actual release notes live on the project's documentation site, not here.

What is Grype?

Grype's entire roadmap is false positives — and it just went code-aware to cut them.

Almost every release in this window targets match accuracy rather than coverage. Go has taken the brunt of it: merging govulndb GO-* records with their GHSA aliases, scoping GHSA twins by shared CVE, disabling stdlib CPE matching by default, and ignoring compiler CVEs when an image contains only a compiled binary. Coverage still widens at the edges — Zarf packages, Ubuntu ESM, Chainguard OSV data, CycloneDX 1.7 input — but it is not where the effort sits.

Fission's release feed carries only RC tags, and none of them say what shipped

◆ Current state

Every entry here is a release candidate — v1.22.0-rc1 and rc2, v1.23.0-rc1, v1.25.0-rc1 — with no final release appearing between them, and the version sequence skips 1.24 entirely. The bodies are whatever the tagging commit said, so what reaches this feed is a dependabot bump, a CLI tool-version refresh, a codegen sync explicitly labelled as having no functional change, and one entry that is nothing but links to an external release-highlights page. The actual release notes live on the project's documentation site, not here.

◆ Where it's heading

What can be read from these tags is infrastructure maintenance rather than product direction: Go dependency updates, helm and kind and skaffold and cosign version refreshes, and regenerated swagger and applyconfiguration files kept in sync with CEL and webhook validation comments in the core API types. That last one is the only entry hinting at anything structural — CEL-based validation on the API types implies declarative validation moving into the CRDs — but the commit itself changes only generated output.

◆ Prediction

This feed does not carry enough to predict product direction; until final releases or their notes appear here rather than only candidate tags, any read of where Fission is heading would be guesswork.

Grype's entire roadmap is false positives — and it just went code-aware to cut them.

◆ Current state

Almost every release in this window targets match accuracy rather than coverage. Go has taken the brunt of it: merging govulndb GO-* records with their GHSA aliases, scoping GHSA twins by shared CVE, disabling stdlib CPE matching by default, and ignoring compiler CVEs when an image contains only a compiled binary. Coverage still widens at the edges — Zarf packages, Ubuntu ESM, Chainguard OSV data, CycloneDX 1.7 input — but it is not where the effort sits.

◆ Where it's heading

The arc runs from naive SBOM-to-CVE matching toward evidence-based matching. Reachability analysis is the clearest marker: grype is beginning to reason about whether vulnerable code is actually reachable rather than merely present. The parallel stream of ecosystem-specific correctness work — RHEL minor version streams, RHSA duplication, distro version parsing — suggests the same per-ecosystem treatment is being worked through one package manager at a time.

◆ Prediction

Reachability shipped for Go only. Extending it to a second ecosystem is the obvious next step, and Java or JavaScript are the likeliest targets given where SBOM false positives concentrate.
