  This is a new major release of kustomize, so there are a few backwards-incompatible changes, most of which are rare use cases, bug fixes with side effects, or things that have been deprecated for multiple releases already:
  

    * To avoid that negative effect only use per pod metrics from pods that are:
    * - ready (so metrics about them should be valid), or
    * - unready but creation and last readiness change timestamps are apart more than 10s (pods that have formerly been ready and so metrics are in at least some cases (pod becoming unready because of overload) very useful).

* Pod priority and preemption is now enabled by default. Even if you don't plan to use this feature, you might need to take some action immediately after upgrading. In multi-tenant clusters where not all users are trusted, you are advised to create appropriate quotas for two default priority classes,...

- The following features are now GA, and the associated feature gates are deprecated and will be removed in v1.15:
  - `CustomPodDNS`
  - `HugePages`
  - `MountPropagation`
  - `PersistentLocalVolumes`
- CoreDNS: The following directives or keywords are deprecated and will be removed in v1.15:

* [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.

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.

- 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]

*   NetworkPolicy objects are now stored in etcd in v1 format. After you upgrade to version 1.9, make sure that all NetworkPolicy objects are migrated to v1. ([#51955](https://github.com/kubernetes/kubernetes/pull/51955), [@danwinship](https://github.com/danwinship))
