  • Zoom App Approval!
    Blackthorn is officially approved on the Zoom Marketplace. Zoom can now be properly used as a part of our Integration with Zoom.
  • We've added an EU server!
    Due to privacy differences between countries, we've added a new server in the EU. If we detect that the request is being made from within the EU, the data will be processed by our European Heroku instance. This will be enabled for all attendees by default.
