- Kubernetes v1.13 moves support for Container Storage Interface to GA. As part of this move Kubernetes now supports CSI v1.0.0 and deprecates support for CSI 0.3 and older releases. Older CSI drivers must be updated to CSI 1.0 and moved to the new kubelet plugin registration directory in order to work with Kubernetes 1.15+. ([#71020](https://github.com/kubernetes/kubernetes/pull/71020), [@saad-ali](https://github.com/saad-ali))

    * Fixes volume detach from shutdown nodes.
* Enable insertId generation, and update Stackdriver Logging Agent image to 0.5-1.5.36-1-k8s. This help reduce log duplication and guarantee log order. ([#68920](https://github.com/kubernetes/kubernetes/pull/68920), [@qingling128](https://github.com/qingling128))

Please see the [Releases Page](https://github.com/kubernetes/kubernetes/releases) for older releases.

Release notes of older releases can be found in:
- [CHANGELOG-1.2.md](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.2.md)

        * At Request audit level or higher, an annotation with key "patch.webhook.admission.k8s.io/round_{round idx}_index_{order idx}" get logged with the JSON payload logging the patch sent by a webhook for given request.

- Kubeadm: do not check if the `/etc/kubernetes/manifests` folder is empty on joining worker nodes during preflight ([#104942](https://github.com/kubernetes/kubernetes/pull/104942), [@SataQiu](https://github.com/SataQiu))

however, kubectl v1.21 and older do not support the new API for ephemeral containers.

- The AnyVolumeDataSource feature is now beta, and the feature gate is enabled by default. In order to provide user feedback on PVCs with data sources, deployers must install the VolumePopulators CRD and the data-source-validator controller.
