Breaking Changes:

• Action required: client-go will no longer have bootstrap
  (k8s.io/client-go/tools/bootstrap) related code. Any reference to it will
  break. Please redirect all references to k8s.io/bootstrap instead.
  (#​67356)

• The methods NewSelfSignedCACert and NewSignedCert now use crypto.Signer
  interface instead of rsa.PrivateKey for certificate creation. This is done
  to allow different kind of private keys (for example: ecdsa).
  (#​69329)

• GetScale and UpdateScale methods have been added for apps/v1 clients
  and with this, no-verb scale clients have been removed.
  (#​70437)

• k8s.io/client-go/util/cert/triple package has been removed.
  (#​70966)

New Features:

• unfinished_work_microseconds is added to the workqueue metrics.
  It can be used to detect stuck worker threads (kube-controller-manager runs many workqueues.).
  (#​70884)

• A method GetPorts is added to expose the ports that were forwarded.
  This can be used to retrieve the locally-bound port in cases where the input was port 0.
  (#​67513)

• Dynamic listers and informers, that work with runtime.Unstructured objects,
  are added. These are useful for writing generic, non-generated controllers.
  (68748)

• The dynamic fake client now supports JSONPatch.
  (#​69330)

• The GetBinding method is added for pods in the fake client.
  (#​69412)

Bug fixes and Improvements:

• The apiVersion and action name values for fake evictions are now set.
  (#​69035)

• PEM files containing both TLS certificate and key can now be parsed in
  arbitrary order. Previously key was always required to be first.
  (#​69536)

• Go clients created from a kubeconfig that specifies a TokenFile now
  periodically reload the token from the specified file.
  (#​70606)

• It is now ensured that oversized data frames are not written to
  spdystreams in remotecommand.NewSPDYExecutor.
  (#​70999)

• A panic occuring on calling scheme.Convert is fixed by populating the fake
  dynamic client scheme. (#​69125)

• Add step to correctly setup permissions for the in-cluster-client-configuration example.
  (#​69232)

• The function Parallelize is deprecated. Use ParallelizeUntil instead.
  (#​68403)

• [k8s.io/apimachinery] Restrict redirect following from the apiserver to
  same-host redirects, and ignore redirects in some cases.
  (#​66516)

API changes

New Features:

• GlusterFS PersistentVolumes sources can now reference endpoints in any
  namespace using the spec.glusterfs.endpointsNamespace field.
  Ensure all kubelets are upgraded to 1.13+ before using this capability.
  (#​60195)

• The dynamic audit configuration
  API is added. (#​67547)

• A new field EnableServiceLinks is added to the PodSpec to indicate whether
  information about services should be injected into pod's environment variables.
  (#​68754)

• CSIPersistentVolume feature, i.e. PersistentVolumes with
  CSIPersistentVolumeSource, is GA. CSIPersistentVolume feature gate is now
  deprecated and will be removed according to deprecation policy.
  (#​69929)

• Raw block volume support is promoted to beta, and enabled by default.
  This is accessible via the volumeDevices container field in pod specs,
  and the volumeMode field in persistent volume and persistent volume claims definitions.
  (#​71167)

Bug fixes and Improvements:

• The default value of extensions/v1beta1 Deployment's RevisionHistoryLimit
  is set to MaxInt32. (#​66605)

• procMount field is no longer incorrectly marked as required in openapi schema.
  (#​69694)

• The caBundle and service fields in admission webhook API objects now correctly
  indicate they are optional. (#​70138)

v9.0.0

Compare Source

Breaking Changes:

• client-go now supports additional non-alpha-numeric characters in UserInfo
  "extra" data keys. It should be updated in order to properly support extra
  data containing "/" characters or other characters disallowed in HTTP headers.
  Old clients sending keys which were %-escaped by the user will have their
  values unescaped by new API servers.
  (#​65799)

• apimachinery/pkg/watch.Until has been moved to
  client-go/tools/watch.UntilWithoutRetry. While switching please consider
  using the new client-go/tools/watch.UntilWithSync or client-go/tools/watch.Until.
  (#​66906)

• [k8s.io/apimachinery] Unstructured metadata accessors now respect omitempty semantics
  i.e. a field having zero value will now be removed from the unstructured metadata map.
  (#​67635)

• [k8s.io/apimachinery] The ObjectConvertor interface is now changed such that
  ConvertFieldLabel func takes GroupVersionKind as an argument instead of just
  version and kind. (#​65780)

• [k8s.io/apimachinery] componentconfig ClientConnectionConfiguration is
  moved to k8s.io/apimachinery/pkg/apis/config.
  (#​66058)

• [k8s.io/apimachinery] Renamed KubeConfigFile to Kubeconfig in
  ClientConnectionConfiguration.
  (#​67149)

• [k8s.io/apimachinery] JSON patch no longer supports int.
  (#​63522)

New Features:

• Add ability to cancel leader election.
  This also proves useful in integration tests where the whole app is started and
  stopped in each test. (#​57932)

• An example showing how to use fake clients in tests is added.
  (#​65291)

• [k8s.io/apimachinery] Create and Update now support CreateOptions and UpdateOptions.
  (#​65105)

Bug fixes and Improvements:

• Decrease the amount of time it takes to modify kubeconfig
  files with large amounts of contexts.
  (#​67093)

• The leader election client now renews timeout.
  (#​65094)

• Switched certificate data replacement from REDACTED to DATA+OMITTED.
  (#​66023)

• Fix listing in the fake dynamic client.
  (#​66078)

• Fix discovery so that plural names are no longer ignored if a singular name is not specified.
  (#​66249)

• Fix kubelet startup failure when using ExecPlugin in kubeconfig.
  (#​66395)

• Fix panic in the fake SubjectAccessReview client when object is nil.
  (#​66837)

• Periodically reload InClusterConfig token.
  (#​67359)

• [k8s.io/apimachinery] Report parsing error in json serializer.
  (#​63668)

• [k8s.io/apimachinery] The metav1.ObjectMeta accessor does not deepcopy
  owner references anymore. In general, the accessor interface does not enforce
  deepcopy nor does it forbid it (e.g. for unstructured.Unstructured).
  (#​64915)

• [k8s.io/apimachinery] Utility functions SetTransportDefaults and DialerFor
  once again respect custom Dial functions set on transports.
  (#​65547)

• [k8s.io/apimachinery] Speed-up conversion function invocation by avoiding
  reflect.Call. Action required: regenerated conversion with conversion-gen.
  (#​65771)

• [k8s.io/apimachinery] Establish "406 Not Acceptable" response for
  unmarshable protobuf serialization error.
  (#​67041)

• [k8s.io/apimachinery] Immediately close the other side of the connection by
  exiting once one side closes when proxying.
  (#​67288)

API changes

Breaking Changes:

• Volume dynamic provisioning scheduling has been promoted to beta.
  ACTION REQUIRED: The DynamicProvisioningScheduling alpha feature gate has been removed.
  The VolumeScheduling beta feature gate is still required for this feature.
  (#​67432)

• The CSI file system type is no longer defaulted to ext4.
  All the production drivers listed under https://kubernetes-csi.github.io/docs/Drivers.html
  were inspected and should not be impacted after this change.
  If you are using a driver not in that list,
  please test the drivers on an updated test cluster first.
  (#​65499)

New Features:

• Support annotations for remote admission webhooks.
  (#​58679)

• Support both directory and block device for local volume
  plugin FileSystem VolumeMode.
  (#​63011)

• Introduce autoscaling/v2beta2 and custom_metrics/v1beta2,
  which implement metric selectors for Object and Pods metrics,
  as well as allowing AverageValue targets on Objects, similar to External metrics.
  (#​64097)

• Add Lease API in the coordination.k8s.io API group.
  (#​64246)

• ProcMount added to SecurityContext and AllowedProcMounts added to PodSecurityPolicy
  to allow paths in the container's /proc to not be masked.
  (#​64283)

• Add the AuditAnnotations field to ImageReviewStatus to allow the
  ImageReview backend to return annotations to be added to the created pod.
  (#​64597)

• SCTP is now supported as additional protocol (alpha) alongside TCP and UDP in
  Pod, Service, Endpoint, and NetworkPolicy.
  (#​64973)

• The PodShareProcessNamespace feature to configure PID namespace sharing
  within a pod has been promoted to beta.
  (#​66507)

• Add TTLSecondsAfterFinished to JobSpec for cleaning up Jobs after they finish.
  (#​66840)

• Add DataSource and TypedLocalObjectReference fields to support
  restoring a volume from a volume snapshot data source.
  (#​67087)

• RuntimeClass is a new API resource for defining different classes of runtimes
  that may be used to run containers in the cluster.
  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. (#​67737)

• 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.
  (#​66936)

Bug fixes and Improvements:

• The DisruptedPods field in PodDisruptionBudgetStatus is now optional.
  (#​63757)

• extensions/v1beta1 Deployment's ProgressDeadlineSeconds now defaults to MaxInt32.
  (#​66581)
