[SIG Multi-cluster]: https://github.com/kubernetes/community/tree/master/sig-federation

### SIG Node

[SIG Node][] is responsible for the components that support the controlled
interactions between pods and host resources, and manage the lifecycle
of pods scheduled on a node.

For the 1.8 release, SIG Node continued to focus
on a broad set of workload types, including hardware and performance

- Added the `access_mode` label to `volume_manager_selinux_*` metrics. ([#123667](https://github.com/kubernetes/kubernetes/pull/123667), [@jsafrane](https://github.com/jsafrane))
- Enhanced cloud provider integrations to support optional, per-Node custom labels that can be supplied and applied to Nodes by the node controller. These extra labels will only be applied where the cloud provider integration supports this feature.

iteration values from 0 up to <code>len(a)-1</code> and does not index into the array
or slice itself. For a <code>nil</code> slice, the number of iterations is 0.
</li>

<li>
For a string value, the "range" clause iterates over the Unicode code points
in the string starting at byte index 0.  On successive iterations, the index value will be the
index of the first byte of successive UTF-8-encoded code points in the string,

### SIG AWS

In v1.13 we worked on tighter integrations of Kubernetes API objects with AWS services. These include three out-of-tree alpha feature releases:

1) Alpha for AWS ALB (Application Load Balancer) integration to Kubernetes Ingress resources.

- Introduce CSI Cluster Registration mechanism to ease CSI plugin discovery and allow CSI drivers to customize Kubernetes' interaction with them. ([#67803](https://github.com/kubernetes/kubernetes/pull/67803), [@saad-ali](https://github.com/saad-ali))

(`k8s.gcr.io`) will continue to be supported for the foreseeable future, but the new name should perform better because it frontends equivalent mirrors in other clouds.  Please point your clusters to the new registry going forward. \n\nAdmission/Policy integrations that have an allowlist of registries need to include `registry.k8s.io` alongside `k8s.gcr.io`.\nAir-gapped environments and image garbage-collection configurations will need to update to pre-pull and preserve required images under `registry.k8s.io`...

- [KCCM] service controller: change the cloud controller manager to make `providerID` a predicate when synchronizing nodes. This change allows load balancer integrations to ensure that  the `providerID` is set when configuring

  * The bootstrap token system now allows token management and expiration
* The [`kubefed` federation bootstrap tool](https://kubernetes.io/docs/tutorials/federation/set-up-cluster-federation-kubefed/) has also graduated to beta.
* Interaction with container runtimes is now through the CRI interface, enabling easier integration of runtimes with the kubelet. Docker remains the default runtime via Docker-CRI (which moves to beta).

* Deprecate auto detecting cloud providers in kubelet. Auto detecting cloud providers go against the initiative for out-of-tree cloud providers as we'll now depend on cAdvisor integrations with cloud providers instead of the core repo. In the near future, `--cloud-provider` for kubelet will either be an empty string or `external`.

  - Support allocatable resources overrides via VMSS tags
  - Add missing stable labels in template nodes
  - Proactively set instance status to deleting on node deletions
  
  ### Cluster API
  - Migrate interaction with the API from using internal types to using Unstructured
  - Improve tests to work better with constrained resources
  - Add support for node autodiscovery
  - Add support for `--cloud-config`
