- Fixed a bug where the device resources allocated to an init container, with `containerRestartPolicy` of `Always`, were erroneously reused by a regular container. ([#120461](https://github.com/kubernetes/kubernetes/pull/120461), [@gjkim...

plugin and the `kubernetes.io/enforce-mountable-secrets` annotation are used together with ephemeral containers.

**Note**: This only impacts the cluster if the ServiceAccount admission plugin is used (most cluster should have this on by default as recommended in https://kubernetes.io/docs/reference/access-authn-authz/admission-controllers/#serviceaccount), the `kubernetes.io/enforce-mountable-secrets` annotation is used by a service account (this annotation is not added by default), and...

- Dynamic Resource Allocation (DRA): using structured parameters with a claim that gets reused between pods may have led to a claim with an invalid state (allocated without a finalizer) which then caused scheduling of pods using the claim to stop.

- Graduated the `LegacyServiceAccountTokenTracking` feature gate to GA. The usage of auto-generated secret-based service account token now produces warnings, and relevant Secrets are labeled with a last-used timestamp (label key `kubernetes.io/legacy-token-last-used`).

- Fixed performance regression in scheduler caused by frequent metric lookup on critical code path. ([#116441](https://github.com/kubernetes/kubernetes/pull/116441), [@alculqu...

  leave unused rules in iptables for a while (up to `--iptables-sync-period`)
  before deleting them. This improves performance by not requiring it to
  check for stale rules on every sync. (In smaller clusters, it will still
  remove unused rules immediately once they are no longer used.)
