- Added a new alpha API: ClusterTrustBundle (`certificates.k8s.io/v1alpha1`).
  A ClusterTrustBundle may be used to distribute [X.509](https://www.itu.int/rec/T-REC-X.509) trust anchors to workloads within the cluster. ([#113218](https://github.com/kubernetes/kubernetes/pull/113218), [@ahmedtd](https://github.com/ahmedtd)) [SIG API Machinery, Auth and Testing]

- DRA drivers: the resource slice controller sometimes didn't react properly when kubelet or someone else deleted a recently created ResourceSlice. It incorrectly assumed that the ResourceSlice still exists and didn't recreate it. ([#132683](https://github.com/kubernetes/kubernetes/pull/132683), [@pohly](https://github.com/pohly))...

   - In version 1.8, enable this behavior by setting the
     `--horizontal-pod-autoscaler-use-rest-clients` flag to `true`.

   - In version 1.9, this behavior will be enabled by default, and must be explicitly
     disabled by setting the `--horizontal-pod-autoscaler-use-rest-clients` flag to `false`.

### Cluster Lifecycle

- the IP allocator in v1.17.0 can return errors such as `the cluster IP <ip> for service <service-name> is not within the service CIDR <cidr>; please recreate`...

- client-go: The `rest.AnonymousClientConfig(*rest.Config) *rest.Config` helper method no longer copies custom `Transport` and `WrapTransport` fields, because those can be used to inject user credentials. ([#75771](https://github.com/kubernetes/kubernetes/pull/75771), [@liggitt](https://github.com/liggitt))...

### Taints and Tolerations
* Add a manager to NodeController that is responsible for removing Pods from Nodes tainted with NoExecute Taints. This feature is beta (as the rest of taints) and enabled by default. It's gated by controller-manager enable-taint-manager flag. ([#40355](https://github.com/kubernetes/kubernetes/pull/40355), [@gmarek](https://github.com/gmarek))

* calico-node addon tolerates all NoExecute and NoSchedule taints by default. ([#57122](https://github.com/kubernetes/kubernetes/pull/57122), [@caseydavenport](https://github.com/caseydavenport))
* Allow kubernetes components to react to SIGTERM signal and shutdown gracefully. ([#57756](https://github.com/kubernetes/kubernetes/pull/57756), [@mborsz](https://github.com/mborsz))

* client-go: restores behavior of populating the BearerToken field in rest.Config objects constructed from kubeconfig files containing tokenFile config, or from in-cluster configuration. An additional BearerTokenFile field is now populated to enable constructed clients to periodically refresh tokens. ([#71713](https://gi...
