- DRA: the resource claim controller now maintains metrics about the total number of ResourceClaims and the number of allocated ResourceClaims. ([#127661](https://github.com/kubernetes/kubernetes/pull/127661), [@pohly](https://github.com/pohly)) [SIG Apps, Instrumentation and Node]

- When scheduling a mix of pods using `ResourceClaims` and others that don't, scheduling a pod with `ResourceClaims` has a lower impact on scheduling latency. ([#121876](https://github.com/kubernetes/kubernetes/pull/121876), [@pohly](https://github.com/pohly))

- The names of ResourceClaims generated from ResourceClaimTemplate are now generated. The base name is still `<pod>-<claim name>`, but a random suffix will avoid name collisions. ([#117351](https://github.com/kubernetes/kubernetes/pull/117351), [@pohly](https://github.com/pohly))...

- Api: validation of a `PodSpec` now rejects invalid `ResourceClaim` and `ResourceClaimTemplate` names. For a pod, the name generated for the `ResourceClaim` when using a template also must be valid. ([#116576](https://github.com/kubernetes/kubernetes/pull/116576), [@pohly](https://github.com/pohly))

- Dynamic Resource Allocation (DRA): in the `pod.spec.recourceClaims` array, the `source` indirection is no longer necessary. Instead of e.g. `source: resourceClaimTemplateName: my-template`, one can write `resourceClaimTemplateName: my-template`. ([#125116](https://github.com/kubernetes/kubernetes/pull/125116),...

- `k8s.io/dynamic-resource-allocation/controller`: `ResourceClaimParameters` and `ResourceClassParameters` validation errors are now visible on `ResourceClaim`, `ResourceClass` and `Pod`. ([#121065](https://github.com/kubernetes/kubernetes/pull/121065), [@byako](https://github.com/byako))
- `k8s.io/dynamic-resource-allocation`: can now handle a `selected` node which isn't listed
