Server requirements

The app sends GET requests to the URL defined by the updater_server_url resource (or the dotfe.updater.uri system property) and expects as response a JSON with the following structure:

{
  "response":[
    {
      "datetime":1612459475,
      "filename":"update.zip",
      "id":"817af9b5b8eab6151c22456634c24dfe",

      "size":1666374431,
      "url":"https://url/update.zip",
