This is a change, that requires updates on the clients.....

I only see it being addressed in the -web client:
https://github.com/aerogear/aerogear-aerodoc-web/blob/6160ae204aa04b64d4504c7e28b6e1cedf04f54d/scripts/services/notifierService.js#L56

Note.... Android and iOS are _not_ subscribing to that newly introduced category.... hence they do not receive the message....
