...
If the MetadataVersion is too old to support controller heartbeats, and EndpointType was passed as "controllers," the controller will return UNSUPPORTED_ENDPOINT_TYPE . This reflects the fact that it doesn't have metadata about the controller endpoints in these older MetadataVersions.
ControllerRegistrationRequest / Response
There will be a new ControllerRegistrationRequest. All controllers will send this to the active controller.
...
The active controller will persist all registrations that are sent in with the correct permissions (CLUSTERACTION on CLUSTER). If the controller is not active, we'll send back a NOT_CONTROLLER error.
ApiVersionsResponse
The ZkMigrationReady field in ApiVersionsResponse is now deprecated, and won't be filled out.
