- AWS cloud provider supports auto-discovering subnets without any `kubernetes.io/cluster/<clusterName>` tags. It also supports additional service annotation `service.beta.kubernetes.io/aws-load-balancer-subnets` to manually configure the subnets. ([#97431](https://github.com/kubernetes/kubernetes/pull/97431), [@kishorj](https://github.com/kishorj))

    * to specify the subnet on which the service's front end IP should be provisioned. The
    * annotation is service.beta.kubernetes.io/azure-load-balancer-internal-subnet and its
    * value is the subnet name (not the subnet ARM ID).  If omitted, the default is the
    * master subnet.  It is ignored if the service is not on Azure, if the type is not

### Action Required

* `kubectl create rolebinding` and `kubectl create clusterrolebinding` no longer allow specifying multiple subjects as comma-separated arguments. Use repeated `--user`, `--group`, or `--serviceaccount` arguments to specify multiple subjects.

### Other notable changes

    * API fields previously capable of storing and returning either `[]` and `null` via JSON API requests (for example, the Endpoints `subsets` field) can now store only `null` when created using the protobuf content-type or stored in etcd using protobuf serialization (the default in 1.6+). JSON API clients should tolerate `null` values for such fields, and treat `null` and `[]` as equivalent...

### Feature

- AWS cloudprovider supports auto-discovering subnets without any kubernetes.io/cluster/<clusterName> tags. It also supports additional service annotation service.beta.kubernetes.io/aws-load-balancer-subnets to manually configure the subnets.

- Avoid marking node as Ready until node has synced with API servers at least once ([#99034](https://github.com/kubernetes/kubernetes/pull/99034), [@ehashman](https://github.com/ehashman)) [SIG Node]
- Cleanup subnet in frontend IP configs to prevent huge subnet request bodies in some scenarios. ([#98290](https://github.com/kubernetes/kubernetes/pull/98290), [@nilo19](https://github.com/nilo19)) [SIG Cloud Provider]
