EmberJs deprecate component lifecycle hook didReceiveAttrs

For the Ember version 2.16,they have removed the arguments passed to the, didReceiveAttrs component lifecycle hooks. Now previously I was getting arguments in the form of object.

newAttrs:

EmptyObject: 
{
  dataTestId: "test-object"
  items: MutableCell {__MUTABLE_CELL__       [id=__ember1555539649631463096066386]: true, __REF__ [id=__ember1555539649631670217952659]: RootPropertyReference, value: Array(27)}
  prompt: SafeString {string: "Select an Initiator Group"}
  required: true
  selected: MutableCell {__MUTABLE_CELL__ [id=__ember1555539649631463096066386]: true, __REF__ [id=__ember1555539649631670217952659]: RootPropertyReference, value: undefined}
  __proto__: Object
}

After deprecation how to get such object in the didReceiveAttrs?
