## Known Issues

### `TopologyAwareHints` feature falls back to default behavior

- The `CSIMigrationAzureFile` feature gate (for the feature which graduated to GA in v1.26) is now unconditionally enabled and will be removed in v1.28. ([#114953](https://github.com/kubernetes/kubernetes/pull/114953), [@enj](https://github.com/enj))

- The `AdvancedAuditing` feature gate that graduated to GA in `v1.12` (and was unconditionally
  enabled) has been removed. ([#118763](https://github.com/kubernetes/kubernetes/pull/118763), [@Shubham82](https://github.com/Shubham82))

([#58574](https://github.com/kubernetes/kubernetes/pull/58574), [@yastij](https://github.com/yastij))

* New alpha feature limits the number of processes running in a pod. Cluster administrators will be able to place limits by using the new kubelet command line parameter --pod-max-pids. Note that since this is a alpha feature they will need to enable the "SupportPodPidsLimit" feature. By default, we do not set any maximum limit, If an administrator wants to enable this, they should enable SupportPodPidsLimit=true...

### SIG-instrumentation

No feature work, but a large refactoring of metrics-server as well as a number of bug fixes.

### SIG-node

SIG-node graduated the PodShareProcessNamespace feature from alpha to beta.  This feature allows a pod spec to request that all containers in a pod share a common process namespaces.

Two alpha features were also added in this release.

- The WatchBookmark feature is promoted to GA. With WatchBookmark feature, clients are able to request watch events with BOOKMARK type.

([#83195](https://github.com/kubernetes/kubernetes/pull/83195), [@wojtek-t](https://github.com/wojtek-t))

SIG Cluster Lifecycle has been focusing on improving kubeadm in order to bring it to GA in a future release, as well as developing the [Cluster API](https://github.com/kubernetes/kube-deploy/tree/master/cluster-api). For kubeadm, most new features, such as support for CoreDNS, IPv6 and Dynamic Kubelet Configuration, have gone in as alpha features. We expect to graduate these features to beta and beyond in the next release. The initial Cluster API spec and GCE sample implementation were...

  * The `--audit-policy-file` option is required if the `AdvancedAuditing` feature is not explicitly turned off (`--feature-gates=AdvancedAuditing=false`) on the API server.
  * The audit log file defaults to JSON encoding when using the advanced auditing feature gate.
  * An audit policy file without either an `apiVersion` or a `kind` field may be treated as invalid.
