# 6.14.2

This Version has improved the licensing system, including support for calculating machine fingerprints using only the MAC addresses of network interfaces.

```
{
  "key":"XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX,
  "type":"NODE_ONLINE",
  "addr" : ["74:04:F1:60:EE:A7", "9C:2D:CD:E8:2A:E5", "00:50:56:C0:00:08"]  
}
```

### Added

* Support for licensing via MAC address.

### Fixed

* `selphid-license-activator` does not show the licensing log.
