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 ClickHouse?

ClickHouse is shipping six active version branches in parallel — but the captured feed has only tags, no notes.

What's visible in the captured feed is high-cadence GitHub release tagging across at least six parallel branches in two weeks: 25.8.x-lts, 25.10.x, 25.12.x, 26.1.x, 26.2.x, and 26.5.x. Each entry is title-only with no release notes captured. The branch fan-out is itself meaningful — ClickHouse is maintaining LTS plus several stable branches simultaneously, which is the cadence pattern of a mature OSS database serving enterprises that pin to specific minor versions.

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.

ClickHouse is shipping six active version branches in parallel — but the captured feed has only tags, no notes.

◆ Current state

What's visible in the captured feed is high-cadence GitHub release tagging across at least six parallel branches in two weeks: 25.8.x-lts, 25.10.x, 25.12.x, 26.1.x, 26.2.x, and 26.5.x. Each entry is title-only with no release notes captured. The branch fan-out is itself meaningful — ClickHouse is maintaining LTS plus several stable branches simultaneously, which is the cadence pattern of a mature OSS database serving enterprises that pin to specific minor versions.

◆ Where it's heading

Without per-release content we can't comment on feature direction. The branch shape says enterprise-grade backporting is alive and well; the new 26.5 branch starting in late April implies a forward-development cycle is underway alongside the maintenance work. Worth fixing the changelog ingest to pull release-note bodies from GitHub before the next pass — there's a real signal here being lost.

◆ Prediction

Once the scraper captures release-note bodies, expect to see continued cherry-pick patches on 25.x-LTS for at least 12 more months in parallel with 26.x feature work. Unable to predict feature direction from version tags alone.
