+# Kubernetes 1.24
+
+**Authors**: [Kubernetes 1.24 Release Team](https://github.com/kubernetes/sig-release/blob/master/releases/release-1.24/release-team.md)
+
+We are excited to announce the release of Kubernetes 1.24, the first release of 2022!
+
+This release consists of 46 enhancements: fourteen enhancements have graduated to stable, 
+fifteen enhancements are moving to beta, and thirteen enhancements are entering alpha. 
+Also, two features have been deprecated, and two features have been removed.     
+
+## Major Themes
+
+### Dockershim Removed from kubelet
+
+After its deprecation in v1.20, the dockershim component has been removed from the kubelet in Kubernetes v1.24.
+From v1.24 onwards, you will need to either use one of the other [supported runtimes](/docs/setup/production-environment/container-runtimes/) (such as containerd or CRI-O) 
+or use cri-dockerd if you are relying on Docker Engine as your container runtime. 
+For more information about ensuring your cluster is ready for this removal, please 
+see [this guide](/blog/2022/03/31/ready-for-dockershim-removal/). 
+
+### Beta APIs Off by Default 
+
+[New beta APIs will not be enabled in clusters by default](https://github.com/kubernetes/enhancements/issues/3136). 
+Existing beta APIs and new versions of existing beta APIs will continue to be enabled by default.
+
+### Signing Release Artifacts
+
+Release artifacts are [signed](https://github.com/kubernetes/enhancements/issues/3031) using [cosign](https://github.com/sigstore/cosign) 
+signatures,
+and there is experimental support for [verifying image signatures](/docs/tasks/administer-cluster/verify-signed-images/). 
+Signing and verification of release artifacts is part of [increasing software supply chain security for the Kubernetes release process](https://github.com/kubernetes/enhancements/issues/3027). 
+
+### OpenAPI v3
+
+Kubernetes 1.24 offers beta support for publishing its APIs in the [OpenAPI v3 format](https://github.com/kubernetes/enhancements/issues/2896). 
+
+### Storage Capacity and Volume Expansion Are Generally Available
+
+[Storage capacity tracking](https://github.com/kubernetes/enhancements/issues/1472) 
+supports exposing currently available storage capacity via [CSIStorageCapacity objects](/docs/concepts/storage/storage-capacity/#api) 
+and enhances scheduling of pods that use CSI volumes with late binding.
+
+[Volume expansion](https://github.com/kubernetes/enhancements/issues/284) adds support 
+for resizing existing persistent volumes. 
+
+### NonPreemptingPriority to Stable
+
+This feature adds [a new option to PriorityClasses](https://github.com/kubernetes/enhancements/issues/902), 
+which can enable or disable pod preemption. 
+
+### Storage Plugin Migration
+
+Work is underway to [migrate the internals of in-tree storage plugins](https://github.com/kubernetes/enhancements/issues/625) to call out to CSI Plugins
+while maintaining the original API.
+The [Azure Disk](https://github.com/kubernetes/enhancements/issues/1490)
+and [OpenStack Cinder](https://github.com/kubernetes/enhancements/issues/1489) plugins
+have both been migrated.
+
+### gRPC Probes Graduate to Beta
+
+With Kubernetes 1.24, the [gRPC probes functionality](https://github.com/kubernetes/enhancements/issues/2727) 
+has entered beta and is available by default. You can now [configure startup, liveness, and readiness probes](/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/#configure-probes) for your gRPC app 
+natively within Kubernetes without exposing an HTTP endpoint or
+using an extra executable.
+
+### Kubelet Credential Provider Graduates to Beta
+
+Originally released as Alpha in Kubernetes 1.20, the kubelet's support for
+[image credential providers](/docs/tasks/kubelet-credential-provider/kubelet-credential-provider/)
+has now graduated to Beta.
+This allows the kubelet to dynamically retrieve credentials for a container image registry
+using exec plugins rather than storing credentials on the node's filesystem.
+
+### Contextual Logging in Alpha
+
+Kubernetes 1.24 has introduced [contextual logging](https://github.com/kubernetes/enhancements/issues/3077) 
+that enables the caller of a function to control all aspects of logging (output formatting, verbosity, additional values, and names).
+
+### Avoiding Collisions in IP allocation to Services
+
+Kubernetes 1.24 introduces a new opt-in feature that allows you to
+[soft-reserve a range for static IP address assignments](/docs/concepts/services-networking/service/#service-ip-static-sub-range)
+to Services.
+With the manual enablement of this feature, the cluster will prefer automatic assignment from 
+the pool of Service IP addresses, thereby reducing the risk of collision. 
+
+A Service `ClusterIP` can be assigned:
+
+* dynamically, which means the cluster will automatically pick a free IP within the configured Service IP range.
+* statically, which means the user will set one IP within the configured Service IP range.
+
+Service `ClusterIP` are unique; hence, trying to create a Service with a `ClusterIP` that has already been allocated will return an error.
+
+### Dynamic Kubelet Configuration is Removed from the Kubelet
+
+After being deprecated in Kubernetes 1.22, Dynamic Kubelet Configuration has been removed from the kubelet. The feature will be removed from the API server in Kubernetes 1.26.
+
+## CNI Version-Related Breaking Change
+
+Before you upgrade to Kubernetes 1.24, please verify that you are using/upgrading to a container 
+runtime that has been tested to work correctly with this release.
+
+For example, the following container runtimes are being prepared, or have already been prepared, for Kubernetes:
+
+* containerd v1.6.4 and later, v1.5.11 and later
+* CRI-O 1.24 and later
+
+Service issues exist for pod CNI network setup and tear down in containerd
+v1.6.0–v1.6.3 when the CNI plugins have not been upgraded and/or the CNI config
+version is not declared in the CNI config files. The containerd team reports, "these issues are resolved in containerd v1.6.4."
+
+With containerd v1.6.0–v1.6.3, if you do not upgrade the CNI plugins and/or
+declare the CNI config version, you might encounter the following "Incompatible
+CNI versions" or "Failed to destroy network for sandbox" error conditions.
+
+## Other Updates
+

+
+### Release Team
+
+This release would not have been possible without the combined efforts of committed individuals 
+comprising the Kubernetes 1.24 release team. This team came together to deliver all of the components 
+that go into each Kubernetes release, including code, documentation, release notes, and more. 
+
+Special thanks to James Laverack, our release lead, for guiding us through a successful release cycle, 
+and to all of the release team members for the time and effort they put in to deliver the v1.24 
+release for the Kubernetes community. 
+
+### Release Theme and Logo 
+
+**Kubernetes 1.24: Stargazer**
+
+{{< figure src="/images/blog/2022-05-03-kubernetes-release-1.24/kubernetes-1.24.png" alt="" class="release-logo" >}}
+
+The theme for Kubernetes 1.24 is _Stargazer_.
+
+Generations of people have looked to the stars in awe and wonder, from ancient astronomers to the 
+scientists who built the James Webb Space Telescope. The stars have inspired us, set our imagination 
+alight, and guided us through long nights on difficult seas.
+
+With this release we gaze upwards, to what is possible when our community comes together. Kubernetes 
+is the work of hundreds of contributors across the globe and thousands of end-users supporting 
+applications that serve millions. Every one is a star in our sky, helping us chart our course.
+
+The release logo is made by [Britnee Laverack](https://www.instagram.com/artsyfie/), and depicts a telescope set upon starry skies and the 
+[Pleiades](https://en.wikipedia.org/wiki/Pleiades), often known in mythology as the “Seven Sisters”. The number seven is especially auspicious 
+for the Kubernetes project, and is a reference back to our original “Project Seven” name.
+
+This release of Kubernetes is named for those that would look towards the night sky and wonder — for 
+all the stargazers out there. ✨
+
