Version 20 released
Version 20 of the program is now available for download. The most significant new feature is the option Block the internet on connection failure. It is an easy way to protect anonymity by blocking access to the internet in case the connection to Mullvad is broken. The traffic destined for the tunnel will be blocked until Disconnect or Quit is selected from the menu or until the connection is reestablished.
