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 Dragonfly?

Dragonfly opens a 2.1 line with metrics that explain why replicas drop.

Dragonfly tagged v2.1.0 on November 4, exporting snapshot counters, a save-in-progress gauge and replica disconnects labeled closed, error or timeout. Before, a replica dropped for stalling was indistinguishable from one whose connection simply closed. The 1.40 and 2.0 lines keep getting small cluster-mode fixes, including faster GetSlotInfo and slot migration that no longer drops writes.

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

Dragonfly opens a 2.1 line with metrics that explain why replicas drop.

◆ Current state

Dragonfly tagged v2.1.0 on November 4, exporting snapshot counters, a save-in-progress gauge and replica disconnects labeled closed, error or timeout. Before, a replica dropped for stalling was indistinguishable from one whose connection simply closed. The 1.40 and 2.0 lines keep getting small cluster-mode fixes, including faster GetSlotInfo and slot migration that no longer drops writes.

◆ Where it's heading

Dragonfly is maturing for production operations: the 2.0 line fixed cluster correctness, and 2.1 starts by making replication and persistence observable from Prometheus. The project says it prefers small incremental features, so 2.1 will likely grow the same way.

◆ Prediction

More metrics and cluster-mode fixes on 2.1, with 1.40 and 2.0 still getting backports for a while.
