     controllers: Windows-to-Windows and Windows-to-MacOS, on L5000 and L5110 controllers.

Known Issues
============
4926127 In this version the SW stack goes down when the last device is disconnected. However, 
        the system tray application will stay up if the last device is disconnected within a few
        seconds of the user changing the settings. 

4926352 When security level is "Secure Connect", after disconnecting and reconnecting devices while
        the PC is in sleep mode, the authorization window will not automatically open but the devices
        still need to be re-authorized.

4926783 When a Thunderbolt Networking session is connected, the SW can creates an icon on the desktop
        to ease the access to the peer shared folders. If non-ASCII characters are used in the remote 
        computer name this icon may not be created and/or not be displayed correctly in the application

4926928 Concurrent install/upgrade can lead the Thunderbolt Software to be partially installed if it is 
        run unattended while another MSI process is already running. In such a case the Thunderbolt
        software should be removed and re-installed.

4926173 When upgrading Thunderbolt software from version 3.0.x, the new driver is not properly installed
        if there is a Thunderbolt Networking already loaded during the upgrade. In such a case the 
        Thunderbolt SW driver in use will stay up and upgrade will not complete until the Thunderbolt
        controller is powered down (e.g. all devices and peers disconnected)


Limitations
============
   -  The Thunderbolt Networking implementation does not support Link aggregation (a.k.a. NIC teaming) 
      via the OS.
