To access these commands on older clients either continue to use a pre-0.8
version of the CLI, or upgrade all clients to 0.8.
### CLI Command Changes
Nomad 0.8 has changed the organization of CLI commands to be based on
subcommands. An example of this change is the change from `nomad alloc-status`
to `nomad alloc status`. All commands have been made to be backwards compatible,
but operators should update any usage of the old style commands to the new style

The behavior of the [advertised RPC
address](/docs/agent/configuration/index.html#rpc-1) has changed to be only used
to advertise the RPC address of servers to client nodes. Server to server
communication is done using the advertised Serf address. Existing cluster's
should not be effected but the advertised RPC address may need to be updated to
allow connecting client's over a NAT.
