Installed Version

  • Version
    Here you can see the version number of JonDo.

  • Date
    This field shows the release timestamp of the currently installed version.

  • Type
    There are two possible versions: the stable version has been thoroughly tested. The beta version, also called developer version, includes all functions that are available at the moment, also those that are still undergoing testing. This is why the beta version is meant for experienced and curious users.

Latest Version

The information here does not refer to the software currently installed on your system, but rather it refers to the JonDo version that can currently be downloaded. Using the dropdown menu Type, you can choose whether it applies to the stable version or the beta version.


  • Anonymous update connection

    Only if direct connection is not possible makes JonDo connect to the update server through the currently active JonDonym service if the respective update server is not available through a direct connection. This could for example be the case if your ISP blocks access to the update server.

    Always (deny non-anonymous connection) will result in update servers being contacted only through JonDonym services. By setting this, you may under circumstances no longer be able to receive updates. But on the other side you are protected against direct manipulation of the software by the creator for your installation cannot be identified.

    Never (allow direct connection only) can make sense if you want to cut cost. For update data transmitted through premium JonDonym services will for compelling technical reasons be accounted for just like any other user data. This setting blocks any updates through the anonymous connection.

  • Show information window if a new JAP/JonDo version is available
    If this option is active, an information window will be shown from which you can update directly whenever a new version of JonDo is available. If it is deactivated, the status bar of the main window will display only a small reminder. JonDo checks for new versions at startup and every 12 hours from then.

  • Show information window when a new version of Java (JRE) is available
    JonDo checks for new JAVA versions at startup and every 12 hours thereafter. If this option is active, an information window will be shown. Upgrading the JRE has to be done manually. More...


This field displays information about the update's installation progress. Furthermore, it shows the results of checks for a new version.
