### SIG Auth

- TokenRequest and TokenRequestProjection are now beta features. To enable these feature, the API server needs to be started with the `--service-account-issuer`, `--service-account-signing-key-file`, and `--service-account-api-audiences` flags.

#### Storage

* [stable] Mount options

  * The ability to specify mount options for volumes is moved from beta to stable.

  * A new `MountOptions` field in the `PersistentVolume` spec is available to specify mount options. This field replaces an annotation.

  * A new `MountOptions` field in the `StorageClass` spec allows configuration of mount options for dynamically provisioned volumes.

- Fix: Mount point may become local without calling NodePublishVolume after node rebooting. ([#119923](https://github.com/kubernetes/kubernetes/pull/119923), [@cvvz](https://github.com/cvvz)) [SIG Node and Storage]

MountPropagation feature is now beta. As a consequence, all volume mounts in containers are now `rslave` on Linux by default. To make this default work in all Linux environments the entire mount tree should be marked as shareable, e.g. via `mount --make-rshared /`. All Linux distributions that use systemd already have the root directory mounted as rshared and hence they need not do anything. In Linux environments without systemd we recommend running `mount --make-rshared /` during boot before docker is started,...

* Fixes issue where subpath readOnly mounts failed ([#63045](https://github.com/kubernetes/kubernetes/pull/63045), [@msau42](https://github.com/msau42))
* Fix stackdriver metrics for node memory using wrong metric type ([#63535](https://github.co/kubernetes/kubernetes/pull/63535), [@serathius](https://github.com/serathius))

resource belongs to. ([#43338](https://github.com/kubernetes/kubernetes/pull/43338), [@fabianofranz](https://github.com/fabianofranz))

* `--service-account-lookup` now defaults to true, requiring the Secret API object containing the token to exist in order for a service account token to be valid. This enables service account tokens to be revoked by deleting the Secret object containing the token. ([#44071](https://github.com/kubernetes/kubernetes/pull/44071), [@liggitt](https://github.com/liggitt))...

    *   Dynamic provisioning is not supported with this feature yet.
*   [alpha] Containerized mount utilities
    *   Allow mount utilities, used to mount volumes, to run inside a container instead of on the host.
*   Bug Fixes

* Add `container_state` label to `running_container_count` kubelet metrics, to get count of containers based on their state(running/exited/created/unknown) ([#81573](https://github.com/kubernetes/kubernetes/pull/81573),...

* An `automountServiceAccountToken` field was added to ServiceAccount and PodSpec objects. If set to `false` on a pod spec, no service account token is automounted in the pod. If set to `false` on a service account, no service account token is automounted for that service account unless explicitly overridden in the pod spec.
