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 Hotjar?

Hotjar's update feed stops in April 2025 — the arc it captures ended mid-sentence.

Hotjar's public update feed carries nothing newer than April 2025, and the entries it does carry arrive in duplicate pairs — a short stub and the full post, a few hours apart. What the archive shows is a product that spent 2024 and early 2025 expanding from passive observation (heatmaps, recordings) into active research: unmoderated User Tests, AI tagging of survey responses, and finally prototype testing.

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.

Hotjar's update feed stops in April 2025 — the arc it captures ended mid-sentence.

◆ Current state

Hotjar's public update feed carries nothing newer than April 2025, and the entries it does carry arrive in duplicate pairs — a short stub and the full post, a few hours apart. What the archive shows is a product that spent 2024 and early 2025 expanding from passive observation (heatmaps, recordings) into active research: unmoderated User Tests, AI tagging of survey responses, and finally prototype testing.

◆ Where it's heading

The direction visible in these entries is a move up the research stack — from watching what users did on a live site toward asking them questions and testing designs before they ship. User Tests removed the moderator, AI tagging removed the manual sorting of open-ended responses, and prototype testing removed the requirement that the thing being tested exist yet. Each step cut a person out of the research loop. Whether that arc continued past April 2025 is not something this feed can answer.

◆ Prediction

No prediction is supportable from these entries. The feed has published nothing for over a year, so any claim about Hotjar's current direction would be invented rather than observed — the only honest read is that this channel has been abandoned or moved elsewhere.
