What is RSS-Bridge?

RSS-Bridge resurfaces after a year with a date tag and a Bluesky fix, but no release notes.

RSS-Bridge generates feeds for sites that dropped theirs, and its releases are batches of community fixes to individual site bridges plus a few new ones. The last documented release was 2025-08-05. A new 2026-09-30 tag has appeared whose only visible change is a Bluesky bridge null-handling fix, with no published notes alongside it.

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.

RSS-Bridge resurfaces after a year with a date tag and a Bluesky fix, but no release notes.

◆ Current state

RSS-Bridge generates feeds for sites that dropped theirs, and its releases are batches of community fixes to individual site bridges plus a few new ones. The last documented release was 2025-08-05. A new 2026-09-30 tag has appeared whose only visible change is a Bluesky bridge null-handling fix, with no published notes alongside it.

◆ Where it's heading

The core is stable PHP and the work lives in the roughly 400 site-specific scrapers, which break whenever a target site changes markup or adds bot protection. Releases have slowed from every few months to once a year, so maintenance is continuing on master faster than it is being packaged.

◆ Prediction

Unclear from the feed whether 2026-09-30 will get a written release; if it does, expect the usual mix of bridge repairs and bot-protection workarounds.

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.
