 * may be added together with the corresponding uinterface version bump.
 * Backward incompatible changes are done by bumping the version number in
 * the protocol and uinterface names and resetting the interface version.
 * Once the protocol is to be declared stable, the 'z' prefix and the
 * version number in the protocol and interface names are removed and the
