Clair vs Gloo Gateway: at a glance
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 Gloo Gateway?
Gloo Gateway ports its restart and empty-config fixes to 1.21; 1.19 gets only dependency bumps.
Gloo Gateway maintains the 1.19, 1.20 and 1.21 lines in parallel. The 13 November batch brings the 1.20 restart fixes to 1.21.20: setup no longer restarts before its first xDS sync, a failed reconcile stops sending empty configs to Envoys, the Proxy store survives a setup re-run, and translation retries with backoff while keeping the last good snapshot. 1.20.32 adds that retry logic to 1.20, and 1.19.28 is dependency updates only.

2.5INFRA · APIS
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.
Gloo Gateway
5.0INFRA · APIS
Gloo Gateway ports its restart and empty-config fixes to 1.21; 1.19 gets only dependency bumps.
◆ Current state
Gloo Gateway maintains the 1.19, 1.20 and 1.21 lines in parallel. The 13 November batch brings the 1.20 restart fixes to 1.21.20: setup no longer restarts before its first xDS sync, a failed reconcile stops sending empty configs to Envoys, the Proxy store survives a setup re-run, and translation retries with backoff while keeping the last good snapshot. 1.20.32 adds that retry logic to 1.20, and 1.19.28 is dependency updates only.
◆ Where it's heading
Three weeks of releases have centred on one failure mode: what happens to live Envoy config when gloo restarts or a reconcile fails. Each patch narrows the window where proxies get empty or stale config, and the fixes now reach all three supported lines except 1.19.
◆ Prediction
Expect the retry-and-keep-last-good-snapshot fix to be backported to 1.19 next, or 1.19 to stay on dependency bumps only; the entries do not show a new feature line.
