  Windows* 10  64-bit

Windows Update submission ID:
- RS3: 1152921504627122006


Supported Thunderbolt Controllers

  DSL6540/6340  Series - "Alpine Ridge"  
  JHL6540/6340  Series - "Alpine Ridge"  
  JHL6240       Series - "Alpine Ridge LP" 


Changes:
========
Version 17.2.71.250
  - Added support for Windows* 10 RS3 Native PCIe Enumeration ("Native Express" mode) and Selective Suspend (RTD3) state.
  - Added support to enable Firmware Update on host controller in USB only mode (Device ID 0x15DC, 0x15DD and 0x15DE).
  - Added support for firmware update on device based on TR-DD (JHL 7440) controller - Including SDK and sample update
  - System Tray application reports software & firmware component versions in a separate menu option that does not require Admin permission.
  - Added UEFI capsule update reference code for Host controller Firmware Update in SDK sample folder
  - Optimized Installer Package for Thunderbolt Software, reducing its size significantly (less than 10Mb)
  - Toast notification improvement, now based on the Action Center instead of persistent notification in the right bottom corner of the screen.
  - This package does not support the PRE-BOOT ACL feature introduced in previous software package 17.1.x
  - Thunderbolt Networking is now working properly with Microsoft Windows bridge functionality (Windows* 10 RS3 required)
  
Version 17.1.64.250
  - Initial support for Windows* 10 RS2 Native Enumeration (FWU SDK and samples updated accordingly as well).
  - Added support for PRE-BOOT ACL feature:
      Devices that can be used for boot or during pre-boot need to be pre-approved. 
      Pre-Boot ACL solution enables device pre boot approval by maintaining an access control list in the BIOS. 
      ACL is maintained by both the SW and the BIOS.
      Main “use case” flow:
        1. User adds one or some entries to the ACL through the TBT SW
        2. TBT SW downloads the ACL into BIOS
        3. On boot, BIOS communicates the ACL to TBT FW
        4. FW can identify connected devices and authorize them in Pre-boot stage
        5. At OS up, TBT SW gets indication on presence of  pre-boot authorized device
  - Added support for Apple* Boot Camp in Secure Connect mode (SL1)
  - Firmware Policy settings window has been removed
  - No more support for older Thunderbolt 1 and 2 host controllers
  - No more support for older version of Windows* 7 and 8.1  

Version 16.3.61.275
  - Added support for Windows* 10 RS2 64-bit.
  - Added check-box to each notification not to show it again. This could be reset through the Settings panel.
  - Added support for Titan Ridge (JHL7xxx series) devices (dock) firmware update through Alpine Ridge 
    (DSL6xxx/JHL6xxx series) host controllers.
  WARNING: 
  - This is the last software package supporting Thunderbolt 1 and 2 host controllers
  - This is the last software package supporting Windows* 7 and 8.1     

Version 16.3.59.250
  - PD information dependencies removed from SW UI, and replaced by additional support via 
    SDK & Samples. Refer to Thunderbolt_SDK_Guide.pdf for more information about new methods:

  - Added new method GetControllerInfo in SDK CMD sample to provide more information on a given
    Thunderbolt host controller
  - Added user notification when update needed for the Thunderbolt™3 port to function properly.
    This notification is triggered when NVM version is less than 16, and applicable to Alpine Ridge
    DSL6540/6340 controllers only 
  - Added support for NonAdmin mode through INF install mode.
    This option is not enabled by default and need customized INF/CAT files.

Fixed Issues
============
Version 17.1.64.250
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. 
        This issue is not relevant anymore since the FW Policy settings form is no more accessible.
        
Version 16.3.59.250
4927300 Thunderbolt Application crashes when clicking quickly multiple times on the Thunderbolt
        systray Application.

        "Thunderbolt(TM) Conditional Application starter" 

4927434 Service crash after entering Sx while device is being authorized.


Version 16.2.55.275
4927384a QoS warning appears on Alpine Ridge device when DP consumes all the link bandwidth.

4927384b QoS warning incorrectly reported when connecting two 4K monitors.

4927271 GUI tree is reported as empty after cold boot to OS while devices are connected.


Version 16.2.52.250
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.

4926536 Application GUI does not pop up on device hot-plug after initial package installation.

4926798 Thunderbolt.exe is managed code and will have impact on boot time even if the Systray 
        Application should not be running (e.g. no Thunderbolt device is connected).

4927148 Once a Thunderbolt networking session is established, restarting one peer may leave the 
        Connection Status of the remote peer to be reported incorrectly as well as the Thunderbolt 
        Networking menu being greyed out, even if the networking functionality is still working.

4927198 Once a Thunderbolt networking session is established, the GUI tree may be not showing the 
        remote peer after this one is restarted.

4927150 In some timing race conditions the Systray Application icon does not appear, and should 
        be launched manually.

4927167 Unable to access remote peer using the "Desktop Icon"/"My computer icon" when the name
        of the remote PC was changed.

4927180 Unable to access remote peer using the "Desktop Icon"/"My computer icon" when the Thunderbolt
        Service was restarted.

4927195 A device white listed in Security Level 1 (i.e. "User Authorization") will not be authorized
        when moving to Security Level 2 (i.e. "Secure Connect") until it is removed from the white list
        and reinserted.

4927199 When no Thunderbolt Controller is present, running manually the Thunderbolt Software may 
        report incorrectly a need for Firmware Update.

4927217 No authorization window appear for device approval after Sx resume when "Wake on Thunderbolt"
        is disabled in BIOS.

4927179 In some languages (ENU, JPN, PTB) the eGPU toast notification is truncated.

4927205 Systray Application does not start after restarting the PC with Thunderbolt Device connected.

4927227 After performing INF upgrade, the Thunderbolt SW is indeed not installed.

4926842 Upon Thunderbolt networking connection, it is possible to delete the peer icon located on the
        desktop, however it will be restored on desktop refresh (pressing F5)


Known Issues
============
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.

4927310 Connecting a Thunderbolt device in the middle of the Thunderbolt Software installation process
        may lead the software to miss the automatic launch when installation is done. 
        Disconnecting the device for at least 10sec and reconnecting it will trigger the software again.
        
Limitations
============
   -  The Thunderbolt Networking implementation does not support Link aggregation (a.k.a. NIC teaming) 
      via the OS.
