Hi, I released additional message feature of DroidKaigi Session API!

The API returns message property, if a session has additional message.

{
  "sessions": [
    {
      "id": "12345",
      "title": "Ultra super very nice Android session",
      "description": "Every Android developers should see this session!",
      "startsAt": "2018-02-09T10:00:00",
