TODO: This document was manually maintained so might be incomplete. The automation effort is tracked in https://github.com/kubernetes/client-go/issues/234. # HEAD (changes that will go into v5) ** Breaking changes** pkg/api and pkg/apis are moved to [k8s.io/api](https://github.com/kubernetes/api). Other kubernetes repositories also import types from there, so they are composable with client-go. Helper functions in pkg/api and pkg/apis are also removed. They are planned to be exported in other repos. The issue is tracked [here](https://github.com/kubernetes/kubernetes/issues/48209#issuecomment-314537745). During the transition, you'll have to copy the helper functions to your projects. # v4.0.0 No significant changes since v4.0.0-beta.0. # v4.0.0-beta.0 **New features:** * Added OpenAPISchema support in the discovery client * [https://github.com/kubernetes/kubernetes/pull/44531](https://github.com/kubernetes/kubernetes/pull/44531) * Added mutation cache filter: MutationCache is able to take the result of update operations and stores them in an LRU that can be used to provide a more current view of a requested object. * [https://github.com/kubernetes/kubernetes/pull/45838](https://github.com/kubernetes/kubernetes/pull/45838/commits/f88c7725b4f9446c652d160bdcfab7c6201bddea) * Moved the remotecommand package (used by `kubectl exec/attach`) to client-go * [https://github.com/kubernetes/kubernetes/pull/41331](https://github.com/kubernetes/kubernetes/pull/41331) * Added support for following redirects to the SpdyRoundTripper * [https://github.com/kubernetes/kubernetes/pull/44451](https://github.com/kubernetes/kubernetes/pull/44451) * Added Azure Active Directory plugin * [https://github.com/kubernetes/kubernetes/pull/43987](https://github.com/kubernetes/kubernetes/pull/43987) **Usability improvements:** * Added several new examples and reorganized client-go/examples * [Related PRs](https://github.com/kubernetes/kubernetes/commits/release-1.7/staging/src/k8s.io/client-go/examples) **API changes:** * Added networking.k8s.io/v1 API * [https://github.com/kubernetes/kubernetes/pull/39164](https://github.com/kubernetes/kubernetes/pull/39164) * ControllerRevision type added for StatefulSet and DaemonSet history. * [https://github.com/kubernetes/kubernetes/pull/45867](https://github.com/kubernetes/kubernetes/pull/45867) * Added support for initializers * [https://github.com/kubernetes/kubernetes/pull/38058](https://github.com/kubernetes/kubernetes/pull/38058) * Added admissionregistration.k8s.io/v1alpha1 API * [https://github.com/kubernetes/kubernetes/pull/46294](https://github.com/kubernetes/kubernetes/pull/46294) **Breaking changes:** * Moved client-go/util/clock to apimachinery/pkg/util/clock * [https://github.com/kubernetes/kubernetes/pull/45933](https://github.com/kubernetes/kubernetes/pull/45933/commits/8013212db54e95050c622675c6706cce5de42b45) * Some [API helpers](https://github.com/kubernetes/client-go/blob/release-3.0/pkg/api/helpers.go) were removed. * Dynamic client takes GetOptions as an input parameter * [https://github.com/kubernetes/kubernetes/pull/47251](https://github.com/kubernetes/kubernetes/pull/47251) **Bug fixes:** * PortForwarder: don't log an error if net.Listen fails.

(https://github.com/kubernetes/kubernetes/pull/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.
