What is Clair?

Clair 4.10 RC can read SBOMs to match Java vulnerabilities.

Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.

What is Robusta?

Robusta's 0.54.0 alpha returns to features: Prometheus tenants by namespace and Holmes fixes.

After a month of image patching and CI changes, Robusta's 0.54.0-alpha.1 carries product work again. It derives the Prometheus tenant from a namespace label in the UI and alert graphs, adds dnsConfig to the forwarder Helm deployment, stops the Holmes Slack bot check from blocking or dropping Slack messages, and retires the grafana-renderer. It also patches another set of Python dependency CVEs and stops self-hosted stores from fetching a Supabase key from SaaS.

Clair 4.10 RC can read SBOMs to match Java vulnerabilities.

◆ Current state

Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.

◆ Where it's heading

Since 4.8 Clair has moved from Red Hat's older OVAL data to VEX, and each release follows Red Hat's security data more closely. 4.10 adds SBOMs as an input, so Clair can match what an image's own manifest declares, not only what it finds on disk.

◆ Prediction

More 4.10 release candidates and then a final are likely; the long gap between releases suggests that could take weeks.

5.0

Robusta's 0.54.0 alpha returns to features: Prometheus tenants by namespace and Holmes fixes.

◆ Current state

After a month of image patching and CI changes, Robusta's 0.54.0-alpha.1 carries product work again. It derives the Prometheus tenant from a namespace label in the UI and alert graphs, adds dnsConfig to the forwarder Helm deployment, stops the Holmes Slack bot check from blocking or dropping Slack messages, and retires the grafana-renderer. It also patches another set of Python dependency CVEs and stops self-hosted stores from fetching a Supabase key from SaaS.

◆ Where it's heading

The release mixes multi-tenant Prometheus support, Holmes AI assistant reliability and fewer SaaS dependencies for self-hosted installs. CVE patching remains a constant in every tag.

◆ Prediction

Further Holmes integration work and multi-tenant monitoring changes are the likeliest next items, alongside the usual CVE bumps.
