- Improved performance of `Endpoint` and `EndpointSlice` controllers when there are a large number of services in a single namespace by making pod-to-service lookup asynchronous.

2. Review and delete any PodSecurityPolicy objects you do not want all pod-creating users to be able to use (NOTE: Privileged users that were making use of those policies will also lose access to those policies). For example:
  * `kubectl delete podsecuritypolicies/my-privileged-policy`
3. After upgrading to 1.5.5, re-create the exported PodSecurityPolicy objects:

[Prevents deletion of Persistent Volume Claims that are used by a pod](https://github.com/kubernetes/enhancements/issues/498) and [Persistent Volumes that are bound to a Persistent Volume Claim](https://github.com/kubernetes/enhancements/issues/499), making it impossible to delete storage that is in use by a pod.

This release also includes [Topology Aware Volume Scheduling](https://github.com/kubernetes/enhancements/issues/490) for local persistent volumes, the stable release of [Detailed...

- PodTopologySpread plugin now excludes terminatingPods when making scheduling decisions. ([#87845](https://github.com/kubernetes/kubernetes/pull/87845), [@Huang-Wei](https://github.com/Huang-Wei)) [SIG Scheduling]

Multi-arch support (EXPERIMENTAL):
  - kubeadm now adds support for docker “schema 2” manifest lists. This is preliminary part of the process of making kubeadm based k8s deployments to support multiple architectures.
Deprecating features:
  - The Alpha feature-gates HighAvailability, SelfHosting, CertsInSecrets are now deprecated, and will be removed in k8s v1.13.0.

A few special functions convert between Go and C types
by making copies of the data. In pseudo-Go definitions:

	// Go string to C string
	// The C string is allocated in the C heap using malloc.
	// It is the caller's responsibility to arrange for it to be

    *   To verify if oneDNN optimizations are on, look for a message with *"oneDNN custom operations are on"* in the log. If the exact phrase is not there, it means they are off.

* Making the `tf.function` type system fully available:

    * `tf.types.experimental.TraceType` now allows custom tf.function inputs to declare Tensor decomposition and type casting support.
