- Fixed the bug where if Endpointslices mirrored from Endpoints by the EndpointSliceMirroring controller they would not reconcile if modified. were not reconciled if modified ([#124131](https://github.com/kubernetes/kubernetes/pull/124131), [@zyjhtangtang](https://github.com/zyjhtangtang)) [SIG Apps and Network]

  commands apply to uninitialized objects. See the
  [initializer documentation](https://kubernetes.io/docs/admin/extensible-admission-controllers/) for more details.

- Added RBAC reconcile commands with `kubectl auth reconcile -f FILE`. When
  passed a file which contains RBAC roles, rolebindings, clusterroles, or
  clusterrolebindings, this command computes covers and adds the missing rules.

- kube-proxy now reconciles Service/Endpoint changes with conntrack table and cleans up only stale UDP flow entries ([#127318](https://github.com/kubernetes/kubernetes/pull/127318), [@aroradaman](https://github.com/aroradaman)) [SIG Network and Windows]
