- Fixes using server-side apply with APIService resources (kubernetes/kubernetes#100713, @kevindelgado) [SIG API Machinery, Apps, Scheduling and Testing]
- Regenerate protobuf code to fix CVE-2021-3121 (kubernetes/kubernetes#100515, @joelsmith) [SIG API Machinery, Auth, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Node and Storage]

- A new alpha-level field,
SupportsFsGroup
, has been introduced for CSIDrivers to allow them to specify whether they support volume ownership and permission modifications. TheCSIVolumeSupportFSGroup
feature gate must be enabled to allow this field to be used. (kubernetes/kubernetes#92001, @huffmanca) [SIG API Machinery, CLI and Storage] - Added pod version skew strategy for seccomp profile to synchronize the deprecated annotations with the new API Server fields. Please see the corresponding section in the KEP for more detailed explanations. (kubernetes/kubernetes#91408, @saschagrunert) [SIG Apps, Auth, CLI and Node]

- a
status
field was added; this field defaults toTrue
, and may only be set toTrue
forApproved
,Denied
, andFailed
conditions - a
lastTransitionTime
field was added - a
Failed
condition type was added to allow signers to indicate permanent failure; this condition can be added via thecertificatesigningrequests/status
subresource. Approved

), storage can be provided by third-party storage vendors and all of the usual volume features work. Volumes don't need to be empt; for example, restoring from snapshot is supported.

CSIStorageCapacity
feature gate, only works for CSI drivers and depends on support for the feature in a CSI driver deployment) (kubernetes/kubernetes#92387, @pohly) [SIG API Machinery, Apps, Auth, Scheduling, Storage and Testing] - Seccomp support has graduated to GA. A new
seccompProfile
field is added to pod and container securityContext objects. Support forseccomp.security.alpha.kubernetes.io/pod
andcontainer.seccomp.security.alpha.kubernetes.io/...
annotations is deprecated, and will be removed in v1.22. (kubernetes/kubernetes#91381, @pjbgf) [SIG Apps, Auth, Node, Release, Scheduling and Testing] - ServiceAppProtocol feature gate is now beta and enabled by default, adding new AppProtocol field to Services and Endpoints. (kubernetes/kubernetes#90023, @robscott) [SIG Apps and Network]
- SetHostnameAsFQDN is a new field in PodSpec. When set to true, the fully qualified domain name (FQDN) of a Pod is set as hostname of its containers. In Linux containers, this means setting the FQDN in the hostname field of the kernel (the nodename field of struct utsname). In Windows containers, this means setting the this means setting the registry value of hostname for the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters to FQDN. If a pod does not have FQDN, this has no effect. (kubernetes/kubernetes#91699, @javidiaz) [SIG Apps, Network, Node and Testing]

Kubernetes API Version: 1.18.20
- Support for the dryRun parameter has been added to the dynamic client. (kubernetes-client/python-base#247, @gravesm)
- The

Kubernetes API Version: 1.18.20
Important Information:
- Python 2 had reached End of Life on January 1, 2020. The Kubernetes Python Client has dropped support for Python 2 from this release (v18.20.0b1) and will no longer provide support to older clients as per the Kubernetes support policy.
Kubernetes API Version: 1.18.17
Important Information:
- The Kubernetes Python client versioning scheme has changed. The version numbers used till Kubernetes Python Client v12.y.z lagged behind the actual Kubernetes minor version numbers. From this release, the client is moving a version format
vY.Z.P
whereY
andZ
are respectively from the Kubernetes versionv1.Y.Z
andP
would incremented due to changes on the Python client side itself. Ref: kubernetes-client#1244 - Python 2 had reached End of Life on January 1, 2020. The Kubernetes Python Client has dropped support for Python 2 from this release (v18.0.0) and will no longer provide support to older clients as per the Kubernetes support policy.

Kubernetes API Version: 1.17.14
Important Information:
- The Kubernetes Python client versioning scheme has changed. The version numbers used till Kubernetes Python Client v12.y.z lagged behind the actual Kubernetes minor version numbers. From this release, the client is moving a version format
vY.Z.P
whereY
andZ
are respectively from the Kubernetes versionv1.Y.Z
andP
would incremented due to changes on the Python client side itself. Ref: kubernetes-client#1244 - Python 2 had reached End of Life on January 1, 2020. The Kubernetes Python Client will drop support for Python 2 from the next release (v18.0.0) and will no longer provide support to older clients as per the Kubernetes support policy.

- Fix bug where sending a status update completely wipes managedFields for some types. (#90032, @apelisse) [SIG API Machinery and Testing]
- Fixes a regression with clients prior to 1.15 not being able to update podIP in pod status, or podCIDR in node spec, against >= 1.16 API servers (#88505, @liggitt) [SIG Apps and Network]
- CustomResourceDefinitions now validate documented API semantics of
x-kubernetes-list-type
andx-kubernetes-map-type
atomic to reject non-atomic sub-types. (#84722, @sttts) - Kube-apiserver: The
AdmissionConfiguration
type accepted by--admission-control-config-file
has been promoted toapiserver.config.k8s.io/v1
with no schema changes. (#85098, @liggitt) - Fixed EndpointSlice port name validation to match Endpoint port name validation (allowing port names longer than 15 characters) (#84481, @robscott)
- CustomResourceDefinitions introduce
x-kubernetes-map-type
annotation as a CRD API extension. Enables this particular validation for server-side apply. (#84113, @enxebre)

Pods can select a RunitmeClass to use via the RuntimeClassName field. This feature is in alpha, and the RuntimeClass feature gate must be enabled in order to use it kubernetes/kubernetes#67737
- The PodShareProcessNamespace feature to configure PID namespace sharing within a pod has been promoted to beta kubernetes/kubernetes#66507
- To address the possibility dry-run requests overwhelming admission webhooks that rely on side effects and a reconciliation mechanism, a new field is being added to admissionregistration.k8s.io/v1beta1.ValidatingWebhookConfiguration and admissionregistration.k8s.io/v1beta1.MutatingWebhookConfiguration so that webhooks can explicitly register as having dry-run support. If a dry-run request is made on a resource that triggers a non dry-run supporting webhook, the request will be completely rejected, with "400: Bad Request". Additionally, a new field is being added to the admission.k8s.io/v1beta1.AdmissionReview API object, exposing to webhooks whether or not the request being reviewed is a dry-run kubernetes/kubernetes#66936
- Add custom object status and scale api kubernetes-client/gen#72

- SchedulingV1beta1Api: Promote priority_class to beta kubernetes/kubernetes#63100
- PodSecurityPolicy now supports restricting hostPath volume mounts to be readOnly and under specific path prefixes kubernetes/kubernetes#58647
- The Sysctls experimental feature has been promoted to beta (enabled by default via the
