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 Nextflow?

Nextflow 26.10.6 fixes caching and Wave retries as the 26.10 line settles.

Nextflow ships dated edge builds plus 25.10, 26.04 and 26.10 stable lines for backports. October was dominated by the Bitbucket Cloud token leak, patched across all three lines. Since then 26.10 has returned to normal maintenance: 26.10.5 added Wave SOCI lazy loading, and 26.10.6 on 12 November fixes resume for enums in modules, includes typed-process stage directives in the task hash, and retries Wave connection failures longer.

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

Nextflow 26.10.6 fixes caching and Wave retries as the 26.10 line settles.

◆ Current state

Nextflow ships dated edge builds plus 25.10, 26.04 and 26.10 stable lines for backports. October was dominated by the Bitbucket Cloud token leak, patched across all three lines. Since then 26.10 has returned to normal maintenance: 26.10.5 added Wave SOCI lazy loading, and 26.10.6 on 12 November fixes resume for enums in modules, includes typed-process stage directives in the task hash, and retries Wave connection failures longer.

◆ Where it's heading

The 26.10 line is in steady patching, with most fixes touching the new typed-process and type-system features and the Wave container service. Several fixes affect task hashing and resume, which suggests the typed syntax is still being hardened for real pipelines.

◆ Prediction

Expect further 26.10.x patches around typed processes and Wave, with new features arriving first in edge builds.
