- E2e test for PodFsGroupChangePolicy ([#96247](https://github.com/kubernetes/kubernetes/pull/96247), [@saikat-royc](https://github.com/saikat-royc)) [SIG Storage and Testing]

- Updated `kube-openapi` to remove invalid defaults: OpenAPI spec no longer includes default of `{}` for certain fields where it did not make sense. ([#120757](https://github.com/kubernetes/kubernetes/pull/120757), [@alexzielenski](https://github.com/alexzielenski))

### Cluster-wide seccomp defaults

A new alpha feature gate `SeccompDefault` has been added to the kubelet, together with a corresponding command line flag `--seccomp-default` and kubelet configuration. If both are enabled, then the kubelet's behavior changes for pods that don't explicitly set a seccomp profile.

  * Fix problems with >2 security groups
* GCP:
  * Enable using gcr.io as a Docker registry mirror.
  * Make bigger master root disks in GCE for large clusters.
  * Change default clusterCIDRs from /16 to /14 allowing 1000 Node clusters by default.
  * Allow Debian Jessie on GCE.
  * Node problem detector addon pod detects and reports kernel deadlocks.
* OpenStack
  * Provider added.
* VSphere:
  * Provider updated.

In 1.23, the `PodSecurity` feature gate is enabled by default.

### Container Runtime Interface (CRI) v1 is default

The Kubelet now supports the CRI `v1` API, which is now the project-wide default.
If a container runtime does not support the `v1` API, Kubernetes will fall back to the `v1alpha2` implementation.

### Bug or Regression

- Disabled a previously on-by-default optimization for the API server where each **watch** response used a dedicated goroutine. The `APIServingWithRoutine` feature gate has been demoted from beta to alpha, and is now off by default.

## Changelog since v1.31.0

## Changes by Kind

### Deprecation

  - `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

- Graduated seccomp profile defaulting to GA.
  
  Set the kubelet `--seccomp-default` flag or `seccompDefault` kubelet configuration field to `true` to make pods on that node default to using the `RuntimeDefault` seccomp profile.
  

There are no urgent upgrade notes for the v1.32 release.
