Kubernetes core shipped a critical kube-openapi fix that corrects type lookups for resources with special characters in their names—the kind of bug that silently breaks schema generation for custom resources.

The kube-openapi update [1] lands a builder fix that uses proper JSON-Pointer escaping when keying definition names, resolving incorrect lookups for types containing '/' or '~' characters. This cascades across all staging modules and vendors the fix everywhere it matters. Parallel to that, promo-tools v4.5.0 [2] adds the --staging-repo flag for kpromo pr, enabling Artifact Registry staging repos—a quality-of-life upgrade for release engineering pipelines [3]. On the infrastructure side, cloud-provider-aws resolved a critical security group leak when CLB services are updated with bring-your-own SG annotations [4], fixing a controller bug that left managed security groups dangling. The DRA test suite cleaned house: etcd lifecycle management [5] now runs directly instead of through shell proxies, and unnecessary killall etcd calls [6] got dropped since etcd is now a regular managed component. kops migrated protobuf handling to google.golang.org/protobuf [7], aligning with upstream Go ecosystem standards. The AnonymousAuthConfigurableEndpoints feature gate was dropped [8], cutting another legacy surface from the codebase.
