- Added a new command line argument `--interactive` to kubectl. The new command line argument lets a user confirm deletion requests per resource interactively. ([#114530](https://github.com/kubernetes/kubernetes/pull/114530), [@ardaguclu](https://github.com/ardaguclu)) [SIG CLI and Testing]

    * clusters. When that var is set to true, the command line flag enabling kubelet
    * client certificate rotation will be added to the kubelet command line.
* Make sure that resources being updated are handled correctly by Quota system ([#52452](https://github.com/kubernetes/kubernetes/pull/52452), [@gnufied](https://github.com/gnufied))

- A kubelet parameter and config option has been added to change the CFS quota period from the default 100ms to some other value between 1µs and 1s. This was done to improve response latencies for workloads running in clusters with guaranteed and burstable QoS classes.

* [Breaking change, client-go]: The WaitFor function returns, probably an ErrWaitTimeout, when the done channel is closed, even if the `WaitFunc` doesn't handle the done channel. ([#72364](https://github.com/kubernetes/kubernetes/pull/72364), [@kdada](https://github.com/kdada))

- The `kube-proxy` command-line documentation was updated to clarify that
  `--bind-address` does not actually have anything to do with binding to an

- Modified command line errors (for example, `kubectl list` -> `unknown command`) that were printed as log message with escaped line breaks instead of a multi-line plain text, making the error hard to read.

That means that, for example, to apply authentication to all the *path operations* in a router it would end up being done in a different file, instead of keeping related logic together.

- YAML documents separators ("---") can now be followed by whitespace and comments ("# ....") on the same line. This fixes a bug where documents starting with a comment after the separator were ignored. Other types of content on the same line will result in an error.
