* [GCP kube-up.sh] Variables that were part of kube-env that were only used for kubelet flags are no longer being set, and are being replaced by the more portable mechanism of the kubelet configuration file. The individual variables in the kube-env metadata entry were never meant to be a stable interface and this release note only applies if you are depending on them.

The main themes of this release are:

- **Custom resources:** CRDs are in widespread use as a way to extend Kubernetes to persist and serve new resource types, and have been available in beta since the 1.7 release. The 1.16 release marks the graduation of CRDs to general availability (GA).

With Kubernetes 1.15 as beta, OpenAPI schemas are also published for CRDs, as long as their schemas are structural.

These changes are reflected in the following Kubernetes enhancements:

- Pod Affinity/AntiAffinity label selectors are now validated in the pod affinity score plugin ([#93758](https://github.com/kubernetes/kubernetes/pull/93758), [@damemi](https://github.com/damemi)) [SIG Scheduling]

- Fixing issue with Winkernel Proxier - ClusterIP Loadbalancers are missing if the ExternalTrafficPolicy is set to Local and the available endpoints are all remoteEndpoints. ([#115999](https://github.com/kubernetes/kubernetes/pull/115999), [@princepereira](https://github.com/princepereira)) [SIG Network]

A security issue was discovered in Kubernetes where a user that can create pods and persistent volumes on Windows nodes may be able to escalate to admin privileges on those nodes. Kubernetes clusters are only affected if they are using an in-tree storage plugin for Windows nodes.

**Affected Versions**:
  - kubelet >= v1.8.0

**Fixed Versions**:
  - kubelet v1.28.4
  - kubelet v1.27.8
  - kubelet v1.26.11

- Fix handling of aws-load-balancer-security-groups annotation. Security-Groups assigned with this annotation are no longer modified by kubernetes which is the expected behaviour of most users. Also no unnecessary Security-Groups are created anymore if this annotation is used.
