admission controller. This facilitates creation of dedicated nodes with extended resources. If operators want to create dedicated nodes with extended resources (such as GPUs, FPGAs, and so on), they are expected to taint the node with extended resource name as the key. This admission controller, if enabled, automatically adds tolerations for such taints to pods requesting extended resources, so users don't have to manually add these tolerations.

## Changelog since v1.8.10

### Action Required

  The API Server will no longer proxy non-101 responses for upgrade requests. This could break proxied backends (such as an extension API server) that respond to upgrade requests with a non-101 response code.

### SIG CLI

* You can now use a security context with Windows containers

There is also a new way to run bleeding edge Windows features from scratch by compiling the windows kubelet and kube-proxy, then using them along with daily builds of other Kubernetes components.
