Dormouse turned out, and, by the time they had settled down
again, the cook had disappeared.

  `Never mind!' said the King, with an air of great relief.
`Call the next witness.'  And he added in an undertone to the
Queen, `Really, my dear, YOU must cross-examine the next witness.
It quite makes my forehead ache!'

- Fixed a bug in the JSON frame reader that could cause it to retain a reference to the underlying array of the byte slice passed to read. ([#123620](https://github.com/kubernetes/kubernetes/pull/123620), [@benluddy](https://github.com/benluddy))

- kubeadm no longer dumps backtrace if it fails to remove the running containers on reset. ([#73951](https://github.com/kubernetes/kubernetes/pull/73951), [@rosti](https://github.com/rosti))

* [alpha] Volume resizing

  * You can now increase the size of a volume by calling the Kubernetes API.

  * For alpha, this feature increases only the size of the underlying volume. It does not support resizing the file system.

  * For alpha, volume resizing supports only Gluster volumes.

* [alpha] Provide capacity isolation and resource management for local ephemeral storage

resourceVersion from the watch cache by default, as in <1.27 (disabling the change in #115096 by default). This mitigates the impact of an etcd watch bug (https://github.com/etcd-io/etcd/pull/17555). If the 1.27 change in #115096 to serve these requests from underlying storage is still desired despite the impact on watch stability, it can be re-enabled with a `WatchFromStorageWithoutResourceVersion` feature gate.

## Changelog since v1.19.0

## What's New (Major Themes)

### Dockershim deprecation

Docker as an underlying runtime is being deprecated. Docker-produced images will continue to work in your cluster with all runtimes, as they always have.

- Fixed CSIDriver API object to allow missing fields. ([#69331](https://github.com/kubernetes/kubernetes/pull/69331), [@jsafrane](https://github.com/jsafrane))
