### Support for cgroups v2 Graduates to Stable

- Removed `/sbin/apparmor_parser` requirement for the AppArmor host validation.
  This allows using AppArmor on distributions which ship the binary in a different path. ([#97968](https://github.com/kubernetes/kubernetes/pull/97968), [@saschagrunert](https://github.com/saschagrunert)) [SIG Node and Testing]

- Added a new (alpha) field, `trafficDistribution`, to the Service `spec` to express preferences for traffic distribution to endpoints. Enabled through the `ServiceTrafficDistribution` feature gate. ([#123487](https://github.com/kubernetes/kubernetes/pull/123487), [@gauravkghildiyal](https://github.com/gauravkghildiyal))

	// within the same node, rack, zone, or even region. Setting this value gives
	// implementations permission to make different tradeoffs, e.g. optimizing for
	// proximity rather than equal distribution of load. Users should not set this
	// value if such tradeoffs are not acceptable.
	ServiceTrafficDistributionPreferClose = "PreferClose"
)

// These are the valid conditions of a service.
const (

	allErrs = append(allErrs, validateServiceExternalTrafficPolicy(service)...)

	// internal traffic policy field
	allErrs = append(allErrs, validateServiceInternalTrafficFieldsValue(service)...)

	// traffic distribution field
	allErrs = append(allErrs, validateServiceTrafficDistribution(service)...)

	return allErrs
}

	// Platform in which Istio is deployed. Possible values are: "openshift" and "gcp"
	// An empty value means it is a vanilla Kubernetes distribution, therefore no special
	// treatment will be considered.
	Platform string `protobuf:"bytes,69,opt,name=platform,proto3" json:"platform,omitempty"`
