### Service Catalog
- **[alpha]** Adds a new API resource `PodPreset` and admission controller to enable defining cross-cutting injection of Volumes and Environment into Pods.

### Volumes
* **[stable]** StorageClass API is promoted to v1 (storage.k8s.io/v1).

beta, adding alpha support for a new CSI driver registry as well as for topology, and adding a number of alpha features to support the use of CSI for “local ephemeral volumes” (that is, volumes that exist for the lifecycle of a pod and contain some injected information, like a token or secret).

With Kubernetes v1.12, SIG Storage also introduced alpha support for [volume snapshotting](https://github.com/kubernetes/enhancements/issues/177). This feature introduces the ability to create/delete...

  - Clients should reload the token from disk periodically (once per minute is recommended) to ensure they continue to use a valid token. `k8s.io/client-go` version v11.0.0+ and v0.15.0+ reload tokens automatically.

    * Update debian-iptables image for CVEs.
    * Change chain name to IP-MASQ to be compatible with the pre-injected masquerade rules.

### Documentation

- Update Japanese translation for kubectl help ([#86837](https://github.com/kubernetes/kubernetes/pull/86837), [@inductor](https://github.com/inductor)) [SIG CLI and Docs]
- `kubectl plugin` now prints a note how to install krew ([#88577](https://github.com/kubernetes/kubernetes/pull/88577), [@corneliusweig](https://github.com/corneliusweig)) [SIG CLI]

    * - Update debian-iptables image for CVEs.
    * - Change chain name to IP-MASQ to be compatible with the
    * pre-injected masquerade rules.
* Fix VMWare VM freezing bug by reverting [#51066](https://github.com/kubernetes/kubernetes/pull/51066) ([#67825](https://github.com/kubernetes/kubernetes/pull/67825), [@nikopen](https://github.com/nikopen))

- client-go: The `rest.AnonymousClientConfig(*rest.Config) *rest.Config` helper method no longer copies custom `Transport` and `WrapTransport` fields, because those can be used to inject user credentials. ([#75771](https://github.com/kubernetes/kubernetes/pull/75771), [@liggitt](https://github.com/liggitt))

- The scheduler retries scheduling Pods rejected by PreFilterResult (PreFilter plugins) more appropriately; it now takes events registered in those rejector PreFilter plugins into consideration.
