TODO: This document was manually maintained so might be incomplete. The automation effort is tracked in kubernetes#234.

Changes in k8s.io/api and k8s.io/apimachinery are mentioned here because k8s.io/client-go depends on them.

v7.0.0

Breaking Changes:

  • Google Cloud Service Account email addresses can now be used in RBAC Role bindings since the default scopes now include the userinfo.email scope. This is a breaking change if the numeric uniqueIDs of the Google service accounts were being used in RBAC role bindings. The behavior can be overridden by explicitly specifying the scope values as comma-separated string in the users[*].config.scopes field in the KUBECONFIG file.

  • [k8s.io/api] The ConfigOK node condition has been renamed to KubeletConfigOk.

New Features:

  • Subresource support is added to the dynamic client.

  • A watch method is added to the Fake Client.

  • ListOptions can be modified when creating a ListWatch.

  • A /token subresource for ServiceAccount is added.

  • If an informer delivery fails, the particular notification is skipped and continued the next time.

  • Certificate manager will no longer wait until the initial rotation succeeds or fails before returning from Start().

  • [k8s.io/api] VolumeScheduling and LocalPersistentVolume features are beta and enabled by default. The PersistentVolume NodeAffinity alpha annotation is deprecated and will be removed in a future release.

  • [k8s.io/api] The PodSecurityPolicy API has been moved to the policy/v1beta1 API group. The PodSecurityPolicy API in the extensions/v1beta1 API group is deprecated and will be removed in a future release.

  • [k8s.io/api] ConfigMap objects now support binary data via a new binaryData field.

  • [k8s.io/api] Service account TokenRequest API is added.

  • [k8s.io/api] FSType is added in CSI volume source to specify filesystems.

  • [k8s.io/api] v1beta1 VolumeAttachment API is added.

  • [k8s.io/api] v1.Pod now has a field ShareProcessNamespace to configure whether a single process namespace should be shared between all containers in a pod. This feature is in alpha preview.

  • [k8s.io/api] Add NominatedNodeName field to PodStatus. This field is set when a pod preempts other pods on the node.

  • [k8s.io/api] Promote CSIPersistentVolumeSource to beta.

  • [k8s.io/api] Promote DNSPolicy and DNSConfig in PodSpec to beta.

  • [k8s.io/api] External metric types are added to the HPA API.

  • [k8s.io/apimachinery] The meta.k8s.io/v1alpha1 objects for retrieving tabular responses from the server (Table) or fetching just the ObjectMeta for an object (as PartialObjectMetadata) are now beta as part of meta.k8s.io/v1beta1. Clients may request alternate representations of normal Kubernetes objects by passing an Accept header like application/json;as=Table;g=meta.k8s.io;v=v1beta1 or application/json;as=PartialObjectMetadata;g=meta.k8s.io;v1=v1beta1. Older servers will ignore this representation or return an error if it is not available. Clients may request fallback to the normal object by adding a non-qualified mime-type to their Accept header like application/json - the server will then respond with either the alternate representation if it is supported or the fallback mime-type which is the normal object response.

Bug fixes and Improvements:

Bug fixes and Improvements:

v5.0.1

Bug fix: picked up a security fix kubernetes/kubernetes#53443 for PodSecurityPolicy.

v5.0.0

New features:

API changes:

Breaking changes:

  • Moved pkg/api and pkg/apis to k8s.io/api. Other kubernetes repositories also import types from there, so they are composable with client-go.

  • Removed helper functions in pkg/api and pkg/apis. They are planned to be exported in other repos. The issue is tracked here. During the transition, you'll have to copy the helper functions to your projects.

  • The discovery client now fetches the protobuf encoded OpenAPI schema and returns openapi_v2.Document

  • Enforced explicit references to API group client interfaces in clientsets to avoid ambiguity.

  • The generic RESTClient type (k8s.io/client-go/rest) no longer exposes LabelSelectorParam or FieldSelectorParam methods - use VersionedParams with metav1.ListOptions instead. The UintParam method has been removed. The timeout parameter will no longer cause an error when using Param().

v4.0.0

No significant changes since v4.0.0-beta.0.

v4.0.0-beta.0

New features:

Usability improvements:

  • Added several new examples and reorganized client-go/examples

API changes:

Breaking changes:

Bug fixes:

v3.0.0

Bug fixes:

  • Use OS-specific libs when computing client User-Agent in kubectl, etc. (kubernetes/kubernetes#44423)
  • kubectl commands run inside a pod using a kubeconfig file now use the namespace specified in the kubeconfig file, instead of using the pod namespace. If no kubeconfig file is used, or the kubeconfig does not specify a namespace, the pod namespace is still used as a fallback. (kubernetes/kubernetes#44570)
  • Restored the ability of kubectl running inside a pod to consume resource files specifying a different namespace than the one the pod is running in. (kubernetes/kubernetes#44862)

v3.0.0-beta.0

  • Added dependency on k8s.io/apimachinery. The impacts include changing import path of API objects like ListOptions from k8s.io/client-go/pkg/api/v1 to k8s.io/apimachinery/pkg/apis/meta/v1.
  • Added generated listers (listers/) and informers (informers/)
  • Kubernetes API changes:
    • Added client support for:
      • authentication/v1
      • authorization/v1
      • autoscaling/v2alpha1
      • rbac/v1beta1
      • settings/v1alpha1
      • storage/v1
    • Changed client support for:
      • certificates from v1alpha1 to v1beta1
      • policy from v1alpha1 to v1beta1
    • Deleted client support for:
      • extensions/v1beta1#Job
  • CHANGED: pass typed options to dynamic client (kubernetes/kubernetes#41887)

v2.0.0

  • Included bug fixes in k8s.io/kuberentes release-1.5 branch, up to commit bde8578d9675129b7a2aa08f1b825ec6cc0f3420

  • Kubernetes API changes
    • Apps API group graduated to v1beta1
    • Policy API group graduated to v1beta1
