* PVC may not be synced to controller local cache in time if PV is bound by external PV binder (e.g. kube-scheduler), double check if PVC is not found to prevent reclaiming PV wrongly. ([#67062](https://github.com/kubernetes/kubernetes/pull/67062), [@cofyc](https://github.com/cofyc))

(or even be just another bound type parameter).
In a process of repeated simplification, the bound type parameters in each type
argument are substituted with the respective type arguments for those type
parameters until each type argument is free of bound type parameters.

<p>
If type arguments contain cyclic references to themselves
through bound type parameters, simplification and thus type
inference fails.

- Volume binding: report UnschedulableAndUnresolvable status instead of an error when bound PVs not found ([#95541](https://github.com/kubernetes/kubernetes/pull/95541), [@cofyc](https://github.com/cofyc)) [SIG Apps, Scheduling and Storage]

volumes created using vSphere. ([#59328](https://github.com/kubernetes/kubernetes/pull/59328), [@divyenpatel](https://github.com/divyenpatel))

* Emit number of bound and unbound persistent volumes as Metrics. This PR adds four kinds of Volume Metrics for kube-controller-manager: bound PVC numbers, unbound PVC numbers, bound PV numbers and unbound PV numbers. The PVC metrics use namespace as dimension and the PV metrics use StorageClassName as its dimension. With these metrics we can better...

- Allowed creating ServiceAccount tokens bound to Node objects.
  This allows users to bind a service account token's validity to a named Node object, similar to Pod bound tokens.

- Added enforcement of an upper cost bound for DRA evaluations of CEL. The API server and scheduler now enforce an upper bound on the cost and runtime steps required for evaluating a CEL expression.

    * [event-exporter addon] Bump event-exporter to 0.2.3 to pick up security fixes.
* PVC may not be synced to controller local cache in time if PV is bound by external PV binder (e.g. kube-scheduler), double check if PVC is not found to prevent reclaiming PV wrongly. ([#67062](https://github.com/kubernetes/kubernetes/pull/67062), [@cofyc](https://github.com/cofyc))

- Fixed consolidate logs for `instance not found` error
  Fixed skip `not found` nodes when reconciling LB backend address pools ([#105188](https://github.com/kubernetes/kubernetes/pull/105188), [@nilo19](https://github.com/nilo19))

 - `kubeadm`: a separate "super-admin.conf" file is now deployed. The User in `admin.conf` is now bound to a new RBAC Group `kubeadm:cluster-admins` that has `cluster-admin` `ClusterRole` access. The User in `super-admin.conf` is now bound to the `system:masters` built-in super-powers / break-glass Group that can bypass RBAC. Before this change, the default `admin.conf` was bound to `system:masters` Group, which was undesired. Executing `kubeadm init phase kubeconfig all` or just `kubeadm...
