* Tensorflow will continue to support NumPy 1.26 until 2025, aligning with community standard deprecation timeline [here](https://scientific-python.org/specs/spec-0000/).

* Hermetic CUDA support is added.

* Changes secret, configMap, downwardAPI and projected volumes to mount read-only, instead of allowing applications to write data and then reverting it automatically. Until version 1.11, setting the feature gate ReadOnlyAPIDataVolumes=false will preserve the old behavior.

## Changelog since v1.20.0

## What's New (Major Themes)

### Deprecation of PodSecurityPolicy

- Finalizer Protection for Service LoadBalancers is now in GA (enabled by default). This feature ensures the Service resource is not fully deleted until the correlating load balancer resources are deleted. ([#85023](https://github.com/kubernetes/kubernetes/pull/85023), [@MrHohn](https://github.com/MrHohn))

  - build: Use go-runner:buster-v2.0.1 (built using go1.15.1)
  - bazel: Replace --features with Starlark build settings flag
  - hack/lib/util.sh: some bash cleanups
    
    - switched one spot to use kube::logging
    - make kube::util::find-binary return an error when it doesn't find
      anything so that hack scripts fail fast instead of with "binary not
      found errors".

* Correct env var name in configure-helper ([#33848](https://github.com/kubernetes/kubernetes/pull/33848), [@mtaufen](https://github.com/mtaufen))
* wait until the pods are deleted completely ([#34778](https://github.com/kubernetes/kubernetes/pull/34778), [@ymqytw](https://github.com/ymqytw))

   ([#109251](https://github.com/kubernetes/kubernetes/pull/109251), [@krmayankk](https://github.com/krmayankk))
- The `gcp` and `azure` auth plugins have been restored to client-go and kubectl until https://issue.k8s.io/111911 is resolved in supported kubectl minor versions. ([#111918](https://github.com/kubernetes/kubernetes/pull/111918), [@liggitt](https://github.com/liggitt))

      endpoint now gets broken when that endpoint becomes non-ready
      (rather than continuing until the endpoint is fully deleted).
  
    - Traffic to a service IP now starts getting rejected (as opposed to
      merely dropped) as soon as there are no longer any *usable*
      endpoints, rather than waiting until all of the terminating
      endpoints have terminated even when those terminating endpoints
