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 Drone?

Drone's source now ships as Harness Open Source, and it last released in August 2025.

Both tracked releases are tagged Harness Open Source from the harness/harness repo, which is where Drone's code now lives. v3.2.0 added Git LFS, PR revert, retargeting and Code Owner auto-assignment; v3.3.0 added favorite repos, tag protection rules and a fix for a Git LFS path-traversal issue. Nothing has shipped since August 2025.

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.

Drone's source now ships as Harness Open Source, and it last released in August 2025.

◆ Current state

Both tracked releases are tagged Harness Open Source from the harness/harness repo, which is where Drone's code now lives. v3.2.0 added Git LFS, PR revert, retargeting and Code Owner auto-assignment; v3.3.0 added favorite repos, tag protection rules and a fix for a Git LFS path-traversal issue. Nothing has shipped since August 2025.

◆ Where it's heading

The product has moved from a CI engine toward a full code-hosting platform with PR workflows and branch/tag governance. The 14-month gap since v3.3.0 points to slow or paused open-source releases.

◆ Prediction

The entries give no sign of a next release; another quiet period is the base case.
