    **Added** experimental support for the `cluster.local` host behavior as defined by
9
    the Kubernetes Multi-Cluster Services (MCS) spec. This feature is off by default,
10
    but can be enabled by setting the following flags in Istio:
11
    `ENABLE_MCS_CLUSTER_LOCAL`, `ENABLE_MCS_HOST` and `ENABLE_MCS_SERVICE_DISCOVERY`.
12
    When enabled, requests to the `cluster.local` host will be routed to only those
13
    endpoints residing within the same cluster as the client.
