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 Postman?

Postman is claiming the space between your app's tests and the APIs it actually depends on.

Two kinds of release sit side by side: steady spec and monitoring work — Smithy 2.0 in Spec Hub, more Monitor regions, version tags on changelogs — and the Application Inventory, which tracks applications, their external API dependencies, and the test coverage validating them.

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.

Postman is claiming the space between your app's tests and the APIs it actually depends on.

◆ Current state

Two kinds of release sit side by side: steady spec and monitoring work — Smithy 2.0 in Spec Hub, more Monitor regions, version tags on changelogs — and the Application Inventory, which tracks applications, their external API dependencies, and the test coverage validating them.

◆ Where it's heading

Postman is moving past the API client toward a dependency map of an organization's software. Wiring the Application Inventory into existing Playwright suites means the map populates from tests teams already run, which is how this kind of inventory avoids becoming a stale spreadsheet.

◆ Prediction

Expect the Application Inventory to grow beyond Playwright into other test runners and CI signals, since its usefulness scales with how much of the dependency graph it captures automatically.
