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 kOps?

kOps deletes gossip DNS and the protokube binary, and spends the room on Akamai.

kOps publishes alpha and beta tags to this feed rather than finals, and 1.37.0-beta.1 is the largest cut in its visible history. Gossip DNS is gone, along with the protokube binary that served it, Classic Load Balancer support for the API, and Kubernetes 1.31. In the same tag Akamai — renamed from Linode across the codebase — grows from SSH-key handling into a provider with its own network model, subnets, instance management and etcd block storage volumes.

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.

kOps deletes gossip DNS and the protokube binary, and spends the room on Akamai.

◆ Current state

kOps publishes alpha and beta tags to this feed rather than finals, and 1.37.0-beta.1 is the largest cut in its visible history. Gossip DNS is gone, along with the protokube binary that served it, Classic Load Balancer support for the API, and Kubernetes 1.31. In the same tag Akamai — renamed from Linode across the codebase — grows from SSH-key handling into a provider with its own network model, subnets, instance management and etcd block storage volumes.

◆ Where it's heading

The deliberate narrowing this feed has shown since 1.36 has stopped being incremental. Removing gossip means every cluster now needs real DNS, which ends the configuration that let kOps stand up clusters without a hosted zone. The room that deletion frees is going two visible places: a genuinely new cloud provider in Akamai, and a smaller binary, via grpcnotrace, a forked text/template that lets the linker prune, and a minimal TOML writer replacing go-toml.

◆ Prediction

Akamai moved from SSH keys to subnets, instances and etcd volumes inside a single tag, so it is the provider most likely to keep gaining tasks next. With a gossip migration guide already written, the remaining 1.37 work is the removal reaching users rather than more subtraction.
