New alpha features include:
* Online volume resizing will increase the filesystem size of a resized volume without requiring a Pod restart.

- Added `kubelet_container_log_size_bytes` metric representing the log file size of a container. ([#70749](https://github.com/kubernetes/kubernetes/pull/70749), [@brancz](https://github.com/brancz))

  1. When configuring a dual-stack cluster, the user must specify both `--node-cidr-mask-size-ipv4` and `--node-cidr-mask-size-ipv6` to set the per-node IP mask sizes, instead of the previous `--node-cidr-mask-size` flag.
  2. The `--node-cidr-mask-size` flag is mutually exclusive with `--node-cidr-mask-size-ipv4` and `--node-cidr-mask-size-ipv6`.

- The new flag `--chunk-size=SIZE` for `kubectl drain` has been promoted to beta, and enabled by default. This flag  may be used to alter the number of items or disable this feature when `0` is passed. ([#100148](https://github.com/kubernetes/kubernetes/pull/100148), [@KnVerey](https://github.com/KnVerey))

- Added metric `apiserver_watch_events_sizes` that can be used to estimate sizes of watch events in the system. ([#80477](https://github.com/kubernetes/kubernetes/pull/80477), [@mborsz](https://github.com/mborsz))

    
- Kubeadm: improve the validation of serviceSubnet and podSubnet.
  ServiceSubnet has to be limited in size, due to implementation details, and the mask can not allocate more than 20 bits.
  PodSubnet validates against the corresponding cluster "--node-cidr-mask-size" of the kube-controller-manager, it fail if the values are not compatible.

- Fix a bug that caused the wrong result length when using --chunk-size and --selector together ([#110735](https://github.com/kubernetes/kubernetes/pull/110735), [@Abirdcfly](https://github.com/Abirdcfly)) [SIG API Machinery and Testing]

- Update kube-apiserver's priority & fairness work estimator such that 'max seats' is MIN(0.15 x nominalCL, nominalCL / handSize)
  
  This fixes a bug where clients with requests using hand size x max seats greater than the nominal concurrency limit can starve other requests in the same priority level. ([#118601](https://github.com/kubernetes/kubernetes/pull/118601), [@andrewsykim](https://github.com/andrewsykim)) [SIG API Machinery]
