* Mechanism of adding `federation domain maps` to kube-dns deployment via `--federations` flag is superseded by adding/updating `federations` key in `kube-system/kube-dns` configmap. If user is using kubefed tool to join cluster federation, adding federation domain maps to kube-dns is already taken care by `kubefed join` and does not need further action.

### Scheduling

  - Opaque Integer Resources (OIRs) are deprecated and will be removed in
    version 1.9. Extended Resources (ERs) are a drop-in replacement for OIRs. You can use
    any domain name prefix outside of the `kubernetes.io/` domain instead of the
    `pod.alpha.kubernetes.io/opaque-int-resource-` prefix.

## Notable Features

### Workloads API (apps/v1beta2)

fetching of public verifying keys, by enabling the Alpha `ExternalServiceAccountTokenSigner` feature gate and specifying `--service-account-signing-endpoint`. The flag value can either be the location of a Unix domain socket on a filesystem, or be prefixed with an @ symbol and name a Unix domain socket in the abstract socket namespace.
