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:

- 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. ([#88689](https://github.com/kubernetes/kubernetes/pull/88689), [@Elias481](https://github.com/Elias481)) [SIG Cloud Provider]

- 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]

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).

- Fixing issue with Winkernel Proxier - ClusterIP Loadbalancers are missing if the ExternalTrafficPolicy is set to Local and the available endpoints are all remoteEndpoints. ([#116000](https://github.com/kubernetes/kubernetes/pull/116000), [@princepereira](https://github.com/princepereira)) [SIG Network]

now `beta` and enabled by default. When enabled, legacy auto-generated service account token secrets are auto-labeled with a `kubernetes.io/legacy-token-invalid-since` label if the credentials have not been used in the time specified by `--legacy-service-account-token-clean-up-period` (defaulting to one year), **and** are referenced from the `.secrets` list of a ServiceAccount object, **and**  are not referenced from pods. This label causes the authentication layer to reject use of the credentials....

Troubleshoot on a node by creating a container running in the host namespaces and with access to the host’s filesystem.
Note that as a new builtin command, `kubectl debug` takes priority over any `kubectl` plugin named “debug”. You will need to rename the affected plugin.
