- Projects which use k8s.io/code-generator and invoke `generate-groups` or `generate-internal-groups.sh` have a new, simpler script (`kube_codegen.sh`) they can use.  The old scripts are deprecated but remain intact. ([#117262](https://github.com/kubernetes/kubernetes/pull/117262), [@thockin](https://github.com/thockin)) [SIG API Machinery and Instrumentation]

* PodSpecs containing parent directory references such as `..` (for example, `../bar`) in hostPath volume path or in volumeMount subpaths must be changed to the simple absolute path. Backsteps `..` are no longer allowed.([#47290](https://github.com/kubernetes/kubernetes/pull/47290), [@jhorwit2](https://github.com/jhorwit2)).


### API Machinery

- DRA kubelet: recovery from mistakes like scheduling a pod onto a node with the required driver not running is a bit simpler now because the kubelet does not block pod deletion unnecessarily.

### SIG Storage

[SIG Storage][] is responsible for storage and volume plugin components.

For the 1.8 release, SIG Storage extended the Kubernetes storage API. In addition to providing simple
volume availability, the API now enables volume resizing and snapshotting. These features are in alpha.
The SIG also focused on providing more control over storage: the ability to set requests and

  Distributions or administrators of Kubernetes may want to control that new Service CIDRs added to the cluster does not overlap with other networks on the cluster, that only belong to a specific range of IPs or just simple retain the existing behavior of only having one ServiceCIDR per cluster.  An example of a Validation Admission Policy to achieve this is:
