- Fixes a 1.30.0 regression in openapi descriptions of imagePullSecrets and hostAliases fields to mark the fields used as keys in those lists as either defaulted or required. ([#124694](https://github.com/kubernetes/kubernetes/pull/124694), [@pmalek](http...

  // Defaults to false.
  // +optional
  optional bool stdin = 1;

  // Stdout if true indicates that stdout is to be redirected for the attach call.
  // Defaults to true.
  // +optional
  optional bool stdout = 2;

  // Stderr if true indicates that stderr is to be redirected for the attach call.
  // Defaults to true.

  optional bool stderr = 3;

	"stdin":     "Stdin if true, redirects the standard input stream of the pod for this call. Defaults to false.",

  - The command `kubeadm config print-defaults` is deprecated in favor of `kubeadm config print init-defaults` and `kubeadm config print join-defaults` ([#69617](https://github.com/kubernetes/kubernetes/pull/69617), [@rosti](https://github.com/rosti))

  - `failurePolicy` default changed from `Ignore` to `Fail` for v1
  - `matchPolicy` default changed from `Exact` to `Equivalent` for v1
  - `timeout` default changed from `30s` to `10s` for v1
  - `sideEffects` default value is removed, and the field made required, and only `None` and `NoneOnDryRun` are permitted for v1

                  back-compatibility, if the protocol is not specified, it defaults
                  to "tcp". If a CIDR is not specified, it will allow traffic from
                  all addresses. To disable all inbound host ports, use the value
                  none. The default value allows ssh access and DHCP. [Default: tcp:22,
                  udp:68, tcp:179, tcp:2379, tcp:2380, tcp:6443, tcp:6666, tcp:6667]'
