ThinOS 9.1.6108
Release date
February 2022
Release summary
Patches or Add-on releases are created to support existing platforms or software releases, correct defects, make enhancements, or add minor features.
Previous versions
Dell Wyse 3040, 5070, 5470, and 5470 All-in-One thin clients--ThinOS 9.1.5067 OptiPlex 3000 Thin Client--ThinOS 9.1.4097
Firmware upgrade
The following firmware upgrade scenarios are supported: ThinOS 8.6_807 > ThinOS 9.1.6108 ThinOS 9.1.3129 or later versions > ThinOS 9.1.6108
NOTE: If you are using earlier versions of ThinOS 8.6, you must first upgrade to ThinOS 8.6_807 and apply the latest BIOS updates before upgrading to ThinOS 9.1.6108. If you are using earlier versions of ThinOS 9.x, you must first upgrade to ThinOS 9.1.3129 or later versions before upgrading to ThinOS 9.1.6108.
NOTE: On thin clients that run ThinOS versions earlier than ThinOS 9.1.6108, you must upgrade the OS image first, and then upgrade the BIOS after the OS image is successfully upgraded. Do not upgrade the BIOS and the OS image together. If you upgrade the BIOS and the OS image together, the BIOS upgrade is ignored, and you cannot upgrade the BIOS to the ignored version anymore. You must upgrade the BIOS to another version. For more information, see the Dell Wyse ThinOS Version 9.1.4234, 9.1.5067, and 9.1.6108 Migration Guide at www.dell.com/ support. For the steps to access documents, see Resources and support.
Important notes
There are chances that after the upgrade the device displays a black screen. You may reboot the device to boot it up correctly.
If the thin client is registered in Wyse Management Suite group 1 and you set Wyse Management Suite group 2 token in group 1 policy, then the group 2 token is applied on GUI but the thin client will still be in group 1. You must reboot the thin client to change the thin client to Wyse Management Suite group 2. NOTE: Dell Technologies recommends that you set a new ThinOS application package or a ThinOS firmware package in Group 1, so that thin client installs the package, and automatically reboots, and changes to Group 2.
If the Live Update option is disabled, the thin client cannot download and install any firmware or package until the next reboot. However, the firmware or packages are downloaded in the following scenarios even when the Live Update option is disabled: When you register the thin client to Wyse Management Suite manually. When you power on the thin client from a power off state.

ThinOS 9.1.6108

When you change the Wyse Management Suite group. When you set a new firmware or an application package in Wyse Management Suite group 2 and then change the device
from group 1 to group 2 before upgrading, the following two notifications are displayed: Wyse Management Suite server or group is changed. System is going to reboot to load full configuration.
Press cancel in 60 seconds to prevent reboot. A new firmware or application is available, do you want to upgrade now or defer to the next reboot? The
changes will automatically be applied in 120 seconds.
On ThinOS 9.1.5067 and earlier versions, if you do not select an option, the thin client reboots after 60 seconds. After the reboot, the new application or firmware is installed and the thin client reboots again. The thin client will be in group 2 after the reboot.
From ThinOS 9.1.6108, a notification for new firmware or application is displayed first. If you do not select an option, the thin client downloads and installs the new application or firmware, and reboots. If you select Next Reboot, then the thin client prompts the WMS server or group change notification.
When a new firmware or an application notification is displayed on your thin client, clicking Next Reboot will: Displays a notification if you have changed the Wyse Management Suite group and if the files are downloaded from the new group. Not display any notification if the new firmware or application is downloaded in the same group, from ThinOS 9.1.6108. Installs the firmware or package after a reboot.
Prerequisites for firmware upgrade
Update the BIOS version of Wyse 5070 Thin Client to 1.3.1 or later before upgrading to ThinOS 9.1.6108. If you upgrade to ThinOS 9.1.6108 with earlier BIOS version and then upgrade the BIOS version to 1.3.1 or later, the device may fail to boot. If there is a boot failure, check if the PTT option is available under security in BIOS Setup. For Wyse 5070 Thin Clients with firmware TPM configuration, the PTT option is available after updating BIOS to 1.3.1 or later versions. You must disable the option and boot into ThinOS if you fail to boot after upgrade BIOS. For latest BIOS versions, see Tested BIOS version for ThinOS 9.1.6108.
Before you migrate from ThinOS 8.6_807 to ThinOS 9.1.6108 or upgrade from ThinOS 9.x to 9.1.6108, power on the system and disable the sleep mode. If the system has entered the sleep mode, you must send the Wakeup On LAN command through Wyse Management Suite before using any real-time commands. To use the Wakeup On LAN command, ensure that the Wakeup On LAN option is enabled in BIOS.
Upgrade from ThinOS 8.6 to ThinOS 9.1.6108 using Wyse Management Suite
If you are running any ThinOS 8.6 version, you must first install the ThinOS 8.6_807 image with the latest BIOS version, and then upgrade to ThinOS 9.1.6108. For the latest BIOS versions, see the Dell Wyse ThinOS Version 8.6_807 Release Notes at www.dell.com/support.
The device reboots after the ThinOS image is downloaded. Once the upgrade completes, the device is automatically registered to Wyse Management Suite. Dell Technologies recommends you to back up your device settings before you initiate the upgrade process. All device settings are erased after you upgrade from ThinOS 8.6 except the following settings:
Wyse Management Suite group token and server settings Static DNS Certificates IEEE802.1x wired authentication settings Wireless connections--The WEP/Sharekey security type is changed to Open as they are not supported in ThinOS 9.1 Proxy settings
NOTE: For more information about how to install the ThinOS 9.1.6108 image, see the Dell Wyse ThinOS Version 9.1.4234, 9.1.5067, and 9.1.6108 Migration Guide at www.dell.com/support.

ThinOS 9.1.6108

Upgrade from ThinOS 9.1.x to ThinOS 9.1.6108 using Wyse Management Suite
Prerequisites Ensure that you are running ThinOS 9.1.3129 or later version on you thin client. The thin client must be registered to Wyse Management Suite. Create a group in Wyse Management Suite with a group token. Download the ThinOS 9.1.6108 (DTOS_9.1.6108.pkg) firmware to upgrade.
Steps 1. Go to the Groups & Configs page and select a group. 2. From the Edit Policies drop-down menu, click ThinOS 9.x. The Configuration Control | ThinOS window is displayed. 3. In the left pane, click Standard. 4. From the Standard menu, expand Firmware, and click OS Firmware Updates.
NOTE: If you cannot locate the OS Firmware Updates option under the Standard tab, use the Advanced tab.
5. Click Browse and select the ThinOS 9.1.6108 firmware to upload. 6. From the Select the ThinOS Firmware to deploy drop-down menu, select the uploaded firmware. 7. Click Save & Publish.
The thin client downloads the firmware to install and restarts. The firmware version is upgraded. NOTE: There are chances that the upgrade might fail with event log stating Failed to install. In such an event, you may reboot the device and upgrade again.

New and enhanced features

Citrix Workspace app updates
Plug-and-play functionality for smart card reader enhancement--ThinOS does not allow to disable smart card plugand-play through Citrix Configuration Editor by modifying DriverName parameter due to ThinOS security concern. Hence, plug-and-play functionality for smart card reader is always enabled from this release.
Webcam redirection (HDX RealTime Webcam Video Compression) for 32-bit apps enhancement--Only 32-bit apps on the virtual desktop with HDX RealTime Webcam Video Compression are supported by ThinOS. Dell Technologies only qualified this feature using Citrix Workspace App 2109 package. With this feature, you can customize the camera resolution and frames per second from System Setup > Peripherals > Camera. You can also customize this feature using Admin Policy Tool or Wyse Management Suite policy settings. HDX RealTime Webcam Video Compression is compatible with most unified communications clients. The feature has been tested for compatibility with Cisco Webex Meetings, Cisco Webex Teams, Cisco Jabber, Microsoft Teams, Skype for Business 365, and Zoom. You can use a 32-bit browser such as Google Chrome or Mozilla Firefox to verify the webcam redirection online. External USB cameras or the integrated camera can be used with HDX RealTime Webcam Video Compression. Webcam bandwidth consumption can vary with webcam models. Different webcams offer different frame rates and resolution. Dell Technologies used the following webcams for initial feature validation:
Microsoft LifeCam HD-3000--Highest supported resolution with HDX RealTime Webcam Video Compression is 1920x800.
Logitech C920, C922, C930e--Highest supported resolution with HDX RealTime Webcam Video Compression is 1600x896.
Wyse 5470 and 5470 All-in-One thin clients with built-in camera.
For the steps to configure camera settings, see Dell Wyse ThinOS 9.1.4234, 9.1.5067, and 9.1.6108 Administrator's Guide at www.dell.com/support.
HDX RealTime Webcam Video Compression limitations
Camera with hardware encoding is not supported in ThinOS.
Since x264 library is not integrated into ThinOS, 64-bit apps with HDX RealTime Webcam Video Compression are not supported by Citrix Workspace App. Hence, only 32-bit apps with HDX RealTime Webcam Video Compression are supported in ThinOS.
Citrix Workspace App 2112 with HDX RealTime Webcam Video Compression works only with built-in camera. The issue is also reproduced in Linux Citrix Workspace app binary. Hence, from this ThinOS release, HDX RealTime Webcam Video Compression is only supported with Citrix Workspace app 2109.
Sometimes, the updated Camera Width, Camera Height and Camera FPS settings does not sync from Wyse Management Suite to the thin client. You must reboot the client for the changes to take effect.
HDX RealTime Webcam Video Compression in ThinOS supports only one webcam at a time. Citrix Workspace Linux binary can update the default webcam by modifying HDXWebCamDevice in $HOME/.ICAClient/wfclient.ini configuration file. For example, add HDXWebCamDevice=/dev/video2 to set the webcam mapped to /dev/video2 in a system. However, ThinOS does not allow to input the value /dev/video2 in VDI Configuration Editor due to security reasons.
If client camera is set to 2304x1296 or 2304x1536 video resolution, the HDX webcam redirection cannot be previewed in the session. This limitation is reproduced in CWA 2109 Linux binary as well.

ThinOS 9.1.6108

If client camera is set to 1920x1080 video resolution, the HDX webcam redirection falls back to 325x288 video resolution in the session. This limitation is reproduced in CWA 2109 Linux binary as well.
HDX webcam camera sometimes does not work on WebEx Meeting call. This limitation is reproduced in CWA 2109 Linux binary as well.
Zoom application video preview sometimes fails when you use Citrix HDX Webcam. This limitation is reproduced in CWA 2109 Linux binary as well.
WebEx application video fails to preview when you use Citrix HDX Webcam. This limitation is reproduced in CWA 2109 Linux binary as well.
External USB camera does not work with Citrix HDX Webcam in Citrix Workspace app 2112. Only the built-in camera works. This limitation is reproduced in CWA 2109 Linux binary as well.
Citrix Workspace app fixed issues Resolved the issue where the cursor color inverting feature does not work after you upgrade or downgrade the Citrix Workspace app package.
NOTE: You must install ThinOS 9.1.6108 firmware before you install Citrix_Workspace_App_21.12.0.18.3.pkg.
Resolved the issue where DriverName in smartcard settings under module.ini is changed from VDSCARDV2.DLL to VDSCARD.DLL.
Citrix Workspace app limitations Graphics issue while using YouTube with Browser Content Redirection (BCR) enabled. Zoom optimization does not support proxy using nonanonymous authentication. Mouse cursor displays a black block in Citrix HDX 3D desktop. Jabra Evolve 75, Jabra Engage 75, and Jabra PRO 9450 headsets do not support answering and disconnecting calls using headset buttons for RTME, Cisco JVDI, Zoom, Cisco WebEx teams VDI, Cisco WebEx Meeting VDI, and Microsoft Teams. Jabra Engage 75 headset supports RTME. Zoom window displays a shadow when you share screen.
Unified communication updates
Cisco Jabber application package is updated to version 14.0.3.406553.1.
NOTE: Answering and disconnecting calls using headset buttons is not supported in Cisco JVDI, Zoom, Cisco WebEx teams VDI, Cisco WebEx Meeting VDI, and Microsoft Teams.
ThinOS enhancements
You can register devices with the Wyse Management Suite using DHCP scope options 201 and 202. The following are the updates in the download and installation process of firmware, BIOS, and application packages files:
The pop-up window for new firmware or application package is prompted before downloading the file. After you click Install Now, the download is initiated.
Once a file is downloaded, it gets installed before the next file is downloaded. After the installation of the downloaded file is finished, the next download is initiated.
OS image is downloaded and installed first. The client reboots after the image is installed. After the reboot, the download and installation of other packages are initiated.
If you set a new firmware or an application package to update from group 2 when your device is in Wyse Management Suite group 1, and then change the device from group 1 to group 2, the notification window that is displayed to initiate the new firmware or application package upgrade is prompted first. After you click the Next Reboot button, the notification window of WMS server or group change is displayed.
If you change the Wyse Management Suite server or group in Central Configuration when there is a notification window with a new available firmware or application package upgrade, a pop-up window is displayed to notify that the upgrade will be terminated.
Added new wireless security type WPA3 Personal and Opportunistic Wireless Encryption (OWE). Wyse 3040 Thin Client does not support WPA3 Personal and OWE. Wyse 5070, 5470, 5470 All-in-One thin clients, and OptiPlex 3000 Thin Client with wireless chipset 9560 do not support OWE. OptiPlex 3000 Thin Client with wireless chipset AX210 supports both WPA3 Personal and OWE with WIFI 6/6e. NOTE: If you disable 11n from Wyse Management Suite policy settings or Admin Policy Tool, WPA3 Personal does not work with some wireless routers.
Added the Energy Star logo to the System Information window of OptiPlex 3000 Thin Clients.

ThinOS 9.1.6108

NOTE: The logo is present only in factory shipped OptiPlex 3000 thin clients.
Updated the battery icons that are displayed on Wyse 5470 Thin Client. When the manual override option is enabled, the audio devices that are manually selected in the Peripherals > Audio tab
take priority. Audio devices remain selected after you reboot the device. Supports configuring proxy for Secure MQTT using PAC/WPAD settings. Added Pulse secure and Global Protect in the VPN Protocol list. The default value is Cisco AnyConnect. You can
connect to VPN with Cisco Anyconnect, Pulse secure, or Global Protect. Added camera control options such as resolution and FPS. The feature currently works in Citrix only. For more information,
see Citrix Workspace app updates.
For more information about the updates, see the Dell Wyse ThinOS 9.1.4234, 9.1.5067, and 9.1.6108 Administrator's Guide and Dell Wyse ThinOS 9.1.4234, 9.1.5067, and 9.1.6108 Migration Guide at www.dell.com/support .

The following firmware upgrade scenarios are supported: ThinOS 8.6_807 > ThinOS 9.1.5067 ThinOS 9.1.3129 or 9.1.4234 > ThinOS 9.1.5067
NOTE: If you are using earlier versions of ThinOS 8.6, you must first upgrade to ThinOS 8.6_807 and apply the latest BIOS updates before upgrading to ThinOS 9.1.5067. If you are using earlier versions of ThinOS 9.x, you must first upgrade to ThinOS 9.1.3129 or later versions before upgrading to ThinOS 9.1.5067. For more information, see the Dell Wyse ThinOS Version 9.1.4234 and 9.1.5067 Migration Guide at www.dell.com/support. For the steps to access documents, see Resources and support.
Important notes
There are chances that after the upgrade the device displays a black screen. You may reboot the device to boot it up correctly.
If the thin client is registered in Wyse Management Suite group 1 and you set Wyse Management Suite group 2 token in group 1 policy, then the group 2 token is applied on GUI but the thin client will still be in group 1. You must reboot the thin client to change the thin client to Wyse Management Suite group 2. NOTE: Dell Technologies recommends that you set a new ThinOS application package or a ThinOS firmware package in Group 1, so that thin client installs the package, and automatically reboots, and changes to Group 2.
If the Live Update option is disabled, the thin client cannot download and install any firmware or package until the next reboot. However, the firmware or packages are downloaded in the following scenarios even when the Live Update option is disabled: When you register the thin client to Wyse Management Suite manually. When you power on the thin client from a power off state. When you change the Wyse Management Suite group.
When you set a new firmware or an application package in Wyse Management Suite group 2 and then change the device from group 1 to group 2 before upgrading, the following two notifications are displayed: Wyse Management Suite server or group is changed. System is going to reboot to load full configuration. Press cancel in 60 seconds to prevent reboot.

ThinOS 9.1.5067

A new firmware or application is available, do you want to upgrade now or defer to the next reboot? The changes will automatically be applied in 120 seconds.
If you do not select an option, the thin client reboots after 60 seconds. After the reboot, the new application or firmware is installed and the thin client reboots again. The thin client will be in group 2 after the reboot.
When a new firmware or an application notification is displayed on your thin client, clicking Next Reboot will: Displays a notification if you have changed the Wyse Management Suite group and if the files are downloaded from the new group. Not display any notification if the new firmware or application is downloaded in the same group. Installs the firmware or package after a reboot.
Prerequisites for firmware upgrade
Update the BIOS version of Wyse 5070 Thin Client to 1.3.1 or later before upgrading to ThinOS 9.1.5067. If you upgrade to ThinOS 9.1.5067 with earlier BIOS version and then upgrade the BIOS version to 1.3.1 or later, the device may fail to boot. If there is a boot failure, check if the PTT option is available under security in BIOS Setup. For Wyse 5070 Thin Clients with firmware TPM configuration, the PTT option is available after updating BIOS to 1.3.1 or later versions. You must disable the option and boot into ThinOS if you fail to boot after upgrade BIOS. For latest BIOS versions, see Tested BIOS version for ThinOS 9.1.5067.
Before you migrate from ThinOS 8.6_807 to ThinOS 9.1.5067 or upgrade from ThinOS 9.x to 9.1.5067, power on the system and disable the sleep mode. If the system has entered the sleep mode, you must send the Wakeup On LAN command through Wyse Management Suite before using any real-time commands. To use the Wakeup On LAN command, ensure that the Wakeup On LAN option is enabled in BIOS.
Upgrade from ThinOS 9.1.x to ThinOS 9.1.5067 using Wyse Management Suite
Prerequisites Ensure that you are running ThinOS 9.1.3129 or later version on you thin client. The thin client must be registered to Wyse Management Suite. Create a group in Wyse Management Suite with a group token. Download the ThinOS 9.1.5067 (DTOS_9.1.5067.pkg) firmware to upgrade.

New and enhanced features

Citrix Workspace app updates
Exporting Citrix Workspace app logs--Citrix Workspace app logs can only be exported from Troubleshooting > General > Export Logs on the ThinOS device.
For more information about how to export Citrix Workspace app logs, see the Dell Wyse ThinOS 9.1.4234 and 9.1.5067 Administrator's Guide at www.dell.com/support.
Keyboard Layout Server Default Mode enhancement--From Citrix Workspace App 2109 and ThinOS 9.1.5067 onwards, only the Server Default mode uses the Scancode. Other Keyboard layout modes such as Specific Keyboard, Client Setting, and Dynamic Sync use the default Unicode. There are no changes to the other keyboard layout modes in Citrix Workspace App 2109.
To configure, do the following:
1. Set the Keyboard Layout Mode to Server Default using Admin Policy Tool or Wyse Management Suite. 2. On Admin Policy Tool or Wyse Management Suite policy settings, go to Advanced tab > VDI Configuration Editor >
Citrix Configuration Editor. 3. In the Citrix INI settings section, click Add Row. 4. From the File drop-down list, select wfclient.ini. 5. From the Operation drop-down list, select Add or Update. 6. In the Section field, enter WFClient. 7. In the Key field, enter KeyboardEventMode. 8. In the Value field, enter Scancode. 9. Sign out or restart the device for settings to take effect.
NOTE: If you want to change the Server Default mode to other keyboard layout modes, you must remove the KeyboardEventMode with Scancode setting from Citrix Configuration Editor.
For more information about how to configure the VDI Configuration Editor, see the Dell Wyse ThinOS 9.1.4234 and 9.1.5067 Administrator's Guide at www.dell.com/support.
Citrix VDA policy setting update--In Citrix VDA 2109 and later versions, the Citrix VDA policy setting Virtual channel allow list is enabled by default. As a result, the non-Citrix virtual channels, such as Zoom, WebEx VDI, WebEx Meetings VDI, JVDI, Imprivata OneSign and HID do not work. You can disable the setting, or find the name of the third-party virtual channel and add it to the virtual channel allow list. For more information, see the Citrix documentation at docs.citrix.com.

ThinOS 9.1.5067

Limitations
After you enable the Citrix Workspace app log feature and join the Microsoft Teams meeting, the ICA session stops responding for a few seconds.
Citrix session gets disconnected if Adaptive Audio is enabled when you connect to a VDI desktop that runs on Citrix VDA 2109. You must disable Adaptive Audio function to connect to Citrix VDA 2109 desktop. This issue is observed in Linux Citrix Workspace app binary. If you are using Desktop Delivery Controller (DDC) version 2109, you can find the Adaptive Audio policy, and disable it using the policy settings. If you are using DDC version 1912, change the registry value of REG_DWORD EnableAdaptiveAudio to 0 in the following registry paths: Desktop VDA (Windows 10)--HKLM\Software\Citrix\Audio Server VDA (Server 2016\2019)--HKLM\Software\WOW6432Node\Citrix\Audio
The video resolution may be downgraded when you close and replay the Multimedia redirection (MMR) enabled video. This is observed when the thin client is connected to a VPN.
If you are using a low-bandwidth network connection, the 1080p MMR video stops playing with no audio output. This is observed in a Citrix ICA session.
Battery status does not appear on the session desktop when you launch a session on Wyse 5470 Thin Client. This issue is resolved in Citrix Workspace app 2111.
The published Skype For Business application cannot connect to RTME. During a Microsoft Teams meeting, echo is observed when you disconnect a headset from the device. Audio noise is observed when recording voice with an analog or USB headset in the VDI session. This issue is observed on
Wyse 5070 Thin Client. Microsoft Teams share screen function is disabled automatically when you switch the mouse to the client during the Teams
call. The Citrix desktop screen does not display correctly when the Citrix policy Use video codec for compression is configured
for the entire screen. The server VDA desktop stops responding when you are using a smart card to reconnect the session. Bluetooth device cannot be detected in the JVDI device list. If you open the camera in a session desktop, you cannot use the camera for other applications. You must log out of the
account and log in back to the desktop. Sometimes, Microsoft teams audio and camera change to None on the Settings Devices list.
Azure Virtual Desktop updates
Windows Virtual Desktop (WVD) is renamed to Azure Virtual Desktop (AVD). Supports camera redirection in an RDP session. Connect your camera to the thin client and launch the RDP session. The
camera is redirected automatically. NOTE: The direct show application feature does not work properly when using the camera redirection in an RDP session.
For more information, see the Dell Wyse ThinOS Version 9.1.4234 and 9.1.5067 Administrator's Guide at www.dell.com/support.
VMware Horizon Blast limitations
Headset Redirection--Dell sound bar SP3022/SB522A USB redirection is not supported on ThinOS. The Blast session stops responding when you use this device. This is a VMware limitation.
Session audio--Sometimes the session has no audio output when you hot plug a headset. As a workaround, you must switch the audio from the ThinOS local system to HD audio and then switch back to Headset.
CPU performance--If you do not sign off from the broker but only disconnects the blast session multiple times, there are a lot of mks processes in the system. This is a VMware limitation.
Webex VDI--Sometimes Webex VDI is not optimized in a Horizon session, As a workaround, you must reboot the device and relaunch the Webex VDI application.

ThinOS 9.1.5067

VDI Configuration Editor
ThinOS enables the IT administrator to configure the VDI-related settings by dynamically modifying the VDI configuration files of your ThinOS device. You can configure the Citrix settings, Horizon Blast settings, and Zoom plug-in settings either using Admin Policy Tool or Wyse Management Suite.
To use the VDI settings feature, you must first upgrade to Wyse Management Suite v3.5.866 using the Configuration UI package v1.5 300 or later. If you are using Wyse Management Suite public cloud, the Configuration UI package is updated automatically by Dell.
NOTE: Ensure that you read the disclaimer that is highlighted on the VDI Configuration Editor page before configuring the options. Improper configuration may lead to VDI applications not work properly. You must also read the Citrix, VMware, and Zoom official documentation from their respective websites to set the relevant VDI settings. All settings are case-sensitive.
To access the configuration page, go to Advanced > VDI Configuration Editor on Wyse Management Suite policy settings or Admin Policy Tool. For more information about how to configure the VDI dynamic settings, see the Dell Wyse ThinOS 9.1.4097, 9.1.4234, 9.1.5067, and 9.1.6108 Administrator's Guide at www.dell.com/support.
NOTE: VDI settings will dynamically write into the VDI configuration files of the device. For settings to take effect, you must log out and log in to the broker again, or configure the settings before logging into the broker.

Citrix Configuration Editor

Added the Resolutions From DDC Table Only option under Peripheral Management > Monitor. When enabled, the display resolution list on the device only shows resolutions from the DDC table.
Added the Ignore Server Certificate Check option under Privacy & Security > SCEP.

This option is disabled by default. You must install a CA certificate first and then request a SCEP certificate by using the administrator URL. When using the administrator URL, you must FQDN with prefix HTTPS. Do not use the IP address in the URL.

If this option is enabled, there is no need to install the CA certificate on the client. You can directly request for a SCEP certificate by using the administrator URL with prefix HTTPS.

NOTE: If you are using earlier versions of ThinOS and if you have used the IP address in the administrator URL with the Ignore Server Certificate Check option disabled, you must change the URL to FQDN. If the Ignore Server Certificate Check option is enabled, there is no need to change the IP address in the administrator URL. The application name WVD is changed to AVD in the Proxy Application List field under Network Configuration > Proxy Settings.
NOTE: If you have already configured WVD as the application name, the proxy functionality still works.

Added the option Show Applications with KEYWORDS:Mandatory under Session Settings > Citrix Session Settings. When this option is enabled and you log in with classic mode or modern mode, only the applications that are configured with KEYWORDS:Mandatory are displayed on the ThinOS desktop.
Added the Login Expire Time option under Broker Settings > Citrix Virtual Apps and Desktops Settings. Use this option to set a timer after you log in to a Citrix session. After the countdown timer expires, you must enter the user credentials again to launch any new desktop or application. After you enter the credentials, the countdown timer starts again. Desktop or applications that you launch before the expiry of the countdown timer remains open and are not affected by this setting.
The On Desktop=None option under Session Settings > Global Session Settings is not applicable to Modern desktop.
Values of Keyboard Layout and Screen Saver Timeout from the client are displayed under System Information on the Devices Details page on Wyse Management Suite.

ThinOS 9.1.5067

ThinOS enhancements
Supports device registration to Wyse Management Suite using secure DNS record fields. You can register ThinOS-based devices to Wyse Management Suite 3.5 or later versions by using secure DNS record fields. If you have not registered your ThinOS client to Wyse Management Suite and if you have set the DNS server with records, the device will automatically register to Wyse Management Suite. NOTE: If both secure DNS records and legacy DNS records are set in the DNS server, the secure DNS records take priority.
Registering devices to Wyse Management Suite using secure DHCP scope options 201 and 202 is not supported. Supports NTFS USB drive mapping.
You can import files or export logs to a USB drive with NTFS format from ThinOS local UI. You can map the USB drive with NTFS format to a Citrix or RDP session. Supports multiple DNS domain suffixes. Each value must be separated by a semicolon (;). Ability to save a new password specified in the prompt window when the current WPA & WPA2 personal wireless connection password is incorrect. Supports authentication to domain controller (NTLM) using the None broker. To set the Authentication to domain controller option, go to Login Experience > Login Settings > Login Type on Wyse Management Suite policy settings or Admin Policy Tool.
If you set the Broker type as None with authentication to domain controller selected, a login window is displayed after you restart the system. Only users in the Active Directory group that are set in Wyse Management Suite can log in to the device. Any policy that is configured in the user policy group is applied to ThinOS.
Displays a message on the First Boot Wizard screen when you reset the device to factory default settings without a network connection.
The application name WVD is changed to AVD for the Apply proxy server on field. Supports the display resolution of about 16000 pixels for a single window in a multidisplay setup. Do not exceed this
resolution.

ThinOS 9.1.4234
Release date
October 2021
Downgrading the ThinOS firmware
If you are downgrading ThinOS 9.1.4234 to ThinOS 8.6, ThinOS 9.0, or ThinOS 9.1 versions that are older than 9.1.3129, you must use the Dell Wyse USB Imaging Tool to install the ThinOS 8.x or 9.x Merlin image that is posted to www.dell.com/support. Before you downgrade, ensure that you disable the secure boot option. If you want to downgrade to ThinOS 9.0, you must also clear Trusted Platform Module (TPM) or Platform Trust Technology (PTT) in BIOS. Else, ThinOS resets to factory settings after each reboot. You can downgrade from ThinOS 9.1.4234 to ThinOS 9.1.3129 using Wyse Management Suite.
Firmware upgrade
The following firmware upgrade scenarios are supported: ThinOS 8.6_807 > ThinOS 9.1.4234 ThinOS 9.1.3129 > ThinOS 9.1.4234
NOTE: If you are using earlier versions of ThinOS 8.6, you must first upgrade to ThinOS 8.6_807 and apply the latest BIOS updates before upgrading to ThinOS 9.1.4234. If you are using ThinOS 9.0, or any version of ThinOS 9.1 that is older than 9.1.3129, you must first upgrade to ThinOS 9.1.3129 before upgrading to ThinOS 9.1.4234.
For more information, see the Dell Wyse ThinOS Version 9.1.4234 Migration Guide at www.dell.com/support. For the steps to access documents, see Resources and support.
Important notes
In Wyse Management Suite 3.5, the device group key is case sensitive. If the existing ThinOS 8.6 device uses a group key with a different case on the previous version of Wyse Management Suite server, the client cannot check in to the Wyse Management Suite server after you upgrade the server to Wyse Management Suite 3.5 and the device to ThinOS 9.1. For more information, see the Dell Wyse Management Suite 3.5 Release Notes and Dell Wyse Management Suite 3.5 Administrator's Guide at www.dell.com/support.
Installation can fail even though the image download is complete. This issue is observed when the package settings are changed in the device group before the device is checked in to Wyse Management Suite from shutdown state.
There are chances that after the upgrade the device displays a black screen. You may reboot the device to boot it up correctly.
If the thin client is registered in Wyse Management Suite group 1 and you set Wyse Management Suite group 2 token in group 1 policy, then the group 2 token is applied on GUI but the thin client will still be in group 1. You must reboot the thin client to change the thin client to Wyse Management Suite group 2. NOTE: Dell Technologies recommends that you set a new 9.1.4234 application package or a 9.1.4234 OS firmware package in Group 1, so that thin client installs the package, and automatically reboots, and changes to Group 2.
If the Live Update option is disabled, the thin client cannot download and install any firmware or package until the next reboot. However, the firmware or packages are downloaded in the following scenarios even when the Live Update option is disabled: When you register the thin client to Wyse Management Suite manually. When you power on the thin client from a power off state. When you change the Wyse Management Suite group.

ThinOS 9.1.4234

When you set a new firmware or an application package in Wyse Management Suite group 2 and then change the device from group 1 to group 2 before upgrading, the following two notifications are displayed: Wyse Management Suite server or group is changed. System is going to reboot to load full configuration. Press cancel in 60 seconds to prevent reboot. A new firmware or application is available, do you want to upgrade now or defer to the next reboot? The changes will automatically be applied in 120 seconds.
If you do not select an option, the thin client reboots after 60 seconds. After the reboot, the new application or firmware is installed and the thin client reboots again. The thin client will be in group 2 after the reboot.
When a new firmware or an application notification is displayed on your thin client, clicking Next Reboot will: Displays a notification if you have changed the Wyse Management Suite group and if the files are downloaded from the new group. Not display any notification if the new firmware or application is downloaded in the same group. Installs the firmware or package after a reboot.
ThinOS 9.1.4234 does not apply OS firmware application package and BIOS firmware in child Select group.
Prerequisites for firmware upgrade
Update the BIOS version of Wyse 5070 Thin Client to 1.3.1 or later before upgrading to ThinOS 9.1.4234. If you upgrade to ThinOS 9.1.4234 with earlier BIOS version and then upgrade the BIOS version to 1.3.1 or later, the device may fail to boot. For latest BIOS versions, see Tested BIOS version for ThinOS 9.1.4234.
Before you migrate from ThinOS 8.6_807 to ThinOS 9.1.4234 or upgrade from ThinOS 9.1.3129 to 9.1.4234, power on the system and disable the sleep mode. If the system has entered the sleep mode, you must send the WOL command through Wyse Management Suite before using any real-time commands. To use the WOL command, ensure that the Wake-On-LAN (WOL) option is enabled in BIOS.
Upgrade from ThinOS 8.6 to ThinOS 9.1.4234 using Wyse Management Suite
If you are running any ThinOS 8.6 version, you must first install the ThinOS 8.6_807 image with the latest BIOS version, and then upgrade to ThinOS 9.1.4234. For the latest BIOS versions, see Tested BIOS version for ThinOS 9.1.4234.
The device reboots after the ThinOS image is downloaded. Once the upgrade completes, the device is automatically registered to Wyse Management Suite. Dell Technologies recommends you to back up your device settings before you initiate the upgrade process. All device settings are erased after you upgrade from ThinOS 8.6 except the following settings:
Wyse Management Suite group token and server settings Static DNS Certificates IEEE802.1x wired authentication settings Wireless connections--The WEP/Sharekey security type is changed to Open as they are not supported in ThinOS
9.1.4234 Proxy settings
NOTE: For more information about how to install the ThinOS 9.1.4234 image, see the Dell Wyse ThinOS Version 9.1.4234 Migration Guide at www.dell.com/support.

If you are using ThinOS version 9.0, upgrade to ThinOS 9.1.3129. If you are using a ThinOS 9.1 version that is older than 9.1.3129, upgrade to ThinOS 9.1.3129. The thin client must be registered to Wyse Management Suite. Download the ThinOS 9.1.4234 (DTOS_9.1.4234.pkg) firmware to upgrade.

ThinOS 9.1.4234

Steps 1. Go to the Groups & Configs page and select a group. 2. From the Edit Policies drop-down menu, click ThinOS 9.x. The Configuration Control | ThinOS window is displayed. 3. In the left pane, click Standard. 4. From the Standard menu, expand Firmware, and click OS Firmware Updates.
NOTE: If you cannot locate the OS Firmware Updates option under the Standard tab, use the Advanced tab.
5. Click Browse and select the ThinOS 9.1.4234 OS firmware to upload. 6. From the Select the ThinOS Firmware to deploy drop-down menu, select the uploaded firmware. 7. Click Save & Publish.
The thin client downloads the firmware to install and restarts. The firmware version is upgraded.
Important notes for upgrading from ThinOS 9.1.3129 to ThinOS 9.1.4234
There are chances that the upgrade might fail with event log stating Failed to install. In such an event, you may reboot the device and upgrade again.
After you upgrade, if Zoom is not launching or Zoom optimization is not working in Blast or Citrix session, remove the zoom package and reinstall it.

New and enhanced features

Citrix Workspace app updates
Browser content redirection (BCR) enhancements--BCR with Chromium Embedded Framework (CEF) is enabled by default. ThinOS does not provide the configuration to change BCR with WebKitGKT+.
Zoom optimization enhancements--Added the HTTP proxy support for anonymous authentication in Zoom optimization. Configure HTTP Proxy server and Proxy Application List as ZOOM in Admin Policy Tool or Wyse Management Suite to make Zoom optimization function through the proxy server. The following are the Zoom limitations: HTTPS proxy server is not supported for Zoom optimization in ThinOS. HTTP proxy server with nonanonymous authentication is not supported in ThinOS.
NetScaler/ADC enhancements--Added NetScaler/ADC Authentication Method. Dell Technologies recommends that you configure the NetScaler/ADC Authentication Method with RSA+LDAP either from the Wyse Management Suite policy or the Admin Policy tool for users who want to use Citrix ADC authentication methods, such as RSA+LDAP with MFA. This setting is supported from Wyse Management Suite 3.5 and later versions.
For more information, see the Dell Wyse ThinOS 9.1.4234 Administrator's Guide at www.dell.com/support.
VMware Horizon Blast updates

Smartphone sync
You can sync your iPhone or Android smartphone into a Blast session. NOTE: Among the Android smartphones, only Huawei phones are tested.
For more information, see the Dell Wyse ThinOS Version 9.1.4234 Administrator's Guide at www.dell.com/support.
Bloomberg keyboard STB 100 mapping
You can connect the keyboard using either single or dual USB cables. No setting changes or redirection is required. All the function keys work without any redirection. For steps to disable redirection, see the Dell Wyse ThinOS Version 9.1.4234 Administrator's Guide at www.dell.com/support.
High Efficiency Video Coding (HEVC) or H.265
In ThinOS 9.1.4234, VMware Blast Extreme supports High Efficiency Video Coding (HEVC). HEVC is also known as H.265. This feature is disabled by default. To use this feature, select the Allow High Efficiency Video Decoding (HEVC) check box from

ThinOS 9.1.4234

Connection Manager > Global Connection Settings > Horizon. You can go to the VMware Horizon Performance tracker and see Encoder Name to verify whether HEVC is working. If the name contains HEVC, the feature is working. HEVC in Blast Extreme requires both the ESXi hosts that support the virtual desktops, and RDSH servers to have NVIDIA Tesla or newer graphics cards to offload the encoding. HEVC does not work with only ESXi CPU encoding. If there are no supported graphics cards present, the H.264 or JPEG/PNG encoding is used. For more information, see the VMware Blast Extreme Optimization Guide at techzone.vmware.com.
NOTE: HEVC requires hardware support including the graphics card, on both the client and the agent side. If either the client or the agent cannot support HEVC, the session falls back to H.264.
Limitations
If you launch a session that has been launched from another device, the HEVC feature does not work. The server uses H.264 in this scenario. To use HEVC, sign off other sessions before connecting to the session from the ThinOS client.
You must upgrade Wyse Management Suite to version 3.5 or later to support the HEVC feature.
Microsoft Teams optimization
VMware Horizon 2106 for the client side includes Microsoft Teams media optimization by default. Media optimization for Microsoft Teams that is installed by default in Horizon Agent, is controlled by a group policy object (GPO). GPO is not enabled by default. You can enable the optimization by using a Group Policy Editor.
For the steps on enabling the optimization using a Group Policy Editor, see the Dell Wyse ThinOS Version 9.1.4234 Administrator's Guide at www.dell.com/support.
NOTE: Install the Horizon Agent before you install Microsoft Teams.
To check whether Microsoft Teams is launched in optimized mode, click the three dots next to your profile picture, and go to About > Version. A banner that says VMware Media Optimized is displayed, indicating that Microsoft Teams has launched in optimized mode. Alternatively, you can click the three dots next to your profile picture, and go to Settings > Devices > Audio devices. . Check whether the local headset names are displayed in the Speakers and Microphone drop-down lists, instead of Virtual DevTap or VDI.
NOTE: This feature is not supported on Wyse 3040 Thin Client.

Microsoft Teams optimization limitations and known issues
Depending on your network bandwidth latency, the audio quality may fluctuate. To avoid this issue, ensure that your network bandwidth is adequate for audio or video call. Dell Technologies recommends 200 KBps or higher network speed for a single client.
Audio is still played through the first headset when you switch to the second headset during the call. This issue is observed when you have installed the JVDI package on the thin client. Workaround is that if you are using Microsoft Teams (or Zoom), do not install the Cisco JVDI package. This issue is due to Cisco limitation.
When using a headset, you cannot answer or end the call through headset buttons. This issue is due to a limitation of Microsoft Teams.
Sharing screen when Microsoft Teams is published as an application is not supported. This issue is due to a limitation of VMware Horizon.
There maybe inconsistency on how the video is displayed during video calls. The issue fixes by itself after 5 minutes. Microsoft Teams optimization is not supported through proxy. Audio may be inconsistent during video calls. Try the following:
Sometimes audio is distorted during a call. Workaround is to change the headset. Sometimes there can be network issues. Ensure that your network bandwidth is adequate for audio and video calls. Dell
Technologies recommends 200 KBps or higher network speed for a single client.
Zoom optimization enhancements
Added the HTTP proxy support for anonymous authentication in Zoom optimization. Configure HTTP Proxy server and Proxy Application List as ZOOM in Admin Policy Tool or Wyse Management Suite to make Zoom optimization function through the proxy server. The following are the Zoom limitations:
HTTPS proxy server is not supported for Zoom optimization in ThinOS. HTTP proxy server with nonanonymous authentication is not supported in ThinOS.

Setting the display resolution higher than 1920x1080 results in a black screen. By default the display audio is disabled. You must enable the display audio in Wyse Management Suite and reboot the
client. Display audio does not update real time. If you change the monitor or the DP port, you must reboot the client to update
the display audio option. Wyse 3040 Thin Client supports only one display audio. If one DP port is working with display audio, then the other DP
port does not work with display audio.

New and enhanced features

Wireless chipset support and limitation for OptiPlex 3000 Thin Client
Intel WiFi 6E AX210 and Intel 9560 are the two wireless chipsets that are supported on OptiPlex 3000 Thin Client. All wireless and Bluetooth software features remain the same. ThinOS 9.1.4097 does not support WiFi 6/6E.
VMware Horizon Blast updates

Bloomberg keyboard STB 100 mapping
You can connect the keyboard using either single or dual USB cables. No setting changes or redirection is required. All the function keys work without any redirection. For steps to disable redirection, see the Dell Wyse ThinOS 9.1.4097, 9.1.4234, and later versions Administrator's Guide at www.dell.com/support.

ThinOS 9.1.4097 123

Microsoft Teams optimization
VMware Horizon 2106 package for the client side includes Microsoft Teams media optimization by default. Media optimization for Microsoft Teams that is installed by default in Horizon Agent, is controlled by a group policy object (GPO). GPO is not enabled by default. You can enable the optimization by using a Group Policy Editor.
For the steps on enabling the optimization using a Group Policy Editor, see the Dell Wyse ThinOS 9.1.4097, , 9.1.4234, and later versions Administrator's Guide at www.dell.com/support.
NOTE: Install the Horizon Agent before you install Microsoft Teams.
To check whether Microsoft Teams is launched in optimized mode, click the three dots next to your profile picture, and go to About > Version. A banner that says VMware Media Optimized is displayed, indicating that Microsoft Teams has launched in optimized mode. Alternatively, you can click the three dots next to your profile picture, and go to Settings > Devices > Audio devices. . Check whether the local headset names are displayed in the Speakers and Microphone drop-down lists, instead of Virtual DevTap or VDI.

Microsoft Teams optimization limitations and known issues
Depending on your network bandwidth latency, the audio quality may fluctuate. To avoid this issue, ensure that your network bandwidth is adequate for audio or video call. Dell Technologies recommends 200 KBps or higher network speed for a single client.
Audio is still played through the first headset when you switch to the second headset during the call. This issue is observed when you have installed the JVDI package on the thin client. Workaround is that if you are using Microsoft Teams (or Zoom), do not install the Cisco JVDI package. This issue is due to Cisco limitation.
When using a headset, you cannot answer or end the call through headset buttons. This issue is due to a limitation of Microsoft Teams.
Sharing screen when Microsoft Teams is published as an application is not supported. This issue is due to a limitation of VMware Horizon.
There maybe inconsistency on how the video is displayed during video calls. The issue fixes by itself after 5 minutes. Audio may be inconsistent during video calls. Try the following:
Sometimes audio is distorted during a call. Workaround is to change the headset. Sometimes there can be network issues. Ensure that your network bandwidth is adequate for audio and video calls. Dell
Technologies recommends 200 KBps or higher network speed for a single client.
Teradici PCoIP update
Updated the Teradici PCoIP package version to 21.03.1_10. No new features are added.
Microsoft Windows Virtual Desktop update
The following peripherals are supported from Microsoft Windows Virtual Desktop version 1.3_1196: Camera--Connect the camera to client, and then launch the RDP session. You must disable the Remote Gateway option for
the camera to work. Printer--RDP session supports LPT, LPD and SMB printers.

New and enhanced features

Citrix Workspace app updates
Citrix Workspace app package is updated to version 21.12.0.18.2. This package is intended for users who want to install the Citrix Workspace app version 2112 on ThinOS.
Invert cursor color
From Citrix Workspace app 2112 and ThinOS 9.1.5067, the cursor color can be inverted based on the background color of a text. As a result, you can easily locate the position of the cursor in between texts. By default, this feature is disabled. To enable cursor color inverting feature, do the following:
Steps 1. On Admin Policy Tool or Wyse Management Suite policy settings, go to Advanced > VDI Configuration Editor > Citrix
Configuration Editor. 2. In the Citrix INI Settings, click Add Row. 3. From the File drop-down list, select wfclient.ini. 4. From the Operation drop-down list, select Add or Update. 5. In the Section field, enter Thinwire3.0. 6. In the Key field, enter InvertCursorEnabled. 7. In the Value field, enter True. 8. Sign out or restart the device for the settings to take effect.
NOTE: If you have enabled the cursor color inverting feature, the Cursor Pattern setting from Advanced > Session Settings > Citrix Session Settings in the Admin Policy Tool or Wyse Management Suite policy settings is deprecated.

Limitations for inverting cursor color
Sometimes the cursor color inverting feature does not work after you upgrade or downgrade the Citrix Workspace app package. Workaround is to remove the cursor setting from Advanced > VDI Configuration Editor > Citrix Configuration Editor and then configure the cursor pattern setting from Advanced > Session Settings > Citrix Session Settings in Admin Policy Tool or Wyse Management Suite policy settings. This issue is planned to be resolved in a future release.
Adaptive audio enhancement
From Citrix Workspace app 2112 and ThinOS 9.1.5067, Adaptive audio works while using User Datagram Protocol (UDP) audio delivery. Adaptive audio is enabled by default. This feature requires VDA version 2112 or later versions. For more information, see the Citrix Virtual Apps and Desktops product documentation at www.docs.citrix.com.

Citrix Workspace app 2112, VMware Horizon 2111, Cisco WebEx Meetings VDI 41.12, Cisco WebEx VDI 41.12, and Zoom 151 5.8.4 application packages for ThinOS

UDP audio through Citrix Gateway
From Citrix Workspace app 2112 and ThinOS 9.1.5067, Citrix Workspace app supports Datagram Transport Layer Security (DTLS) protocol for UDP audio. As a result, you can access the UDP audio through Citrix Gateway. By default, this feature is disabled.

Prerequisites Ensure that UDP audio is enabled in ThinOS. To configure the settings, do the following: 1. On Admin Policy Tool or Wyse Management Suite policy settings, go to Advanced > Session Settings > Citrix Session
Settings. 2. Select the Enable UDP audio check box. 3. Select Audio quality as Medium. Ensure that Citrix Audio quality policy is High or Medium in Citrix Studio. 4. Sign off from the session and the broker for the changes to take effect.
Steps 1. On Admin Policy Tool or Wyse Management Suite policy settings, go to Advanced > VDI Configuration Editor > Citrix
Configuration Editor. 2. In the Citrix INI Settings, click Add Row. 3. From the File drop-down list, select module.ini. 4. From the Operation drop-down list, select Add or Update. 5. In the Section field, enter WFClient. 6. In the Key field, enter EnableUDPThroughGateway. 7. In the Value field, enter True. 8. Sign out or restart the device for the settings to take effect.
Disable UDP audio through Citrix Gateway feature
Steps 1. On Admin Policy Tool or Wyse Management Suite policy settings, go to Advanced > Session Settings > Citrix Session
Settings. 2. Clear the Enable UDP audio check box. 3. On Admin Policy Tool or Wyse Management Suite policy settings, go to Advanced > VDI Configuration Editor > Citrix
Configuration Editor. 4. Remove the EnableUDPThroughGateway setting. 5. Sign out or restart the device for the settings to take effect.
Smart card reader enhancement
From Citrix Workspace app 2112 and ThinOS 9.1.5067, Citrix Workspace app supports plug and play functionality for smart card reader. When you insert a smart card, the smart card reader detects the smart card in the server and the client. You can plug and play multiple cards simultaneously, and all these cards are detected. This feature is enabled by default.
Disable smart card plug and play
Steps 1. On Admin Policy Tool or Wyse Management Suite policy settings, go to Advanced > VDI Configuration Editor > Citrix
Configuration Editor. 2. In the Citrix INI Settings, click Add Row. 3. From the File drop-down list, select module.ini. 4. From the Operation drop-down list, select Add or Update.

5. In the Section field, enter SmartCard. 6. In the Key field, enter DriverName. 7. In the Value field, enter VDSCARD.DLL. 8. Sign out or restart the device for the settings to take effect.
Smart card reader limitations
This feature is sometimes disabled after you upgrade or downgrade the Citrix Workspace app package. DriverName in smartcard settings under module.ini is changed from VDSCARDV2.DLL to VDSCARD.DLL. This issue is planned to be resolved in a future release. As a workaround, do the following: 1. On Admin Policy Tool or Wyse Management Suite policy settings, go to Advanced > VDI Configuration Editor > Citrix
Configuration Editor. 2. In the Citrix INI Settings, click Add Row. 3. From the File drop-down list, select module.ini. 4. From the Operation drop-down list, select Add or Update. 5.

If you are using Desktop Delivery Controller (DDC) version 2109, you can find the Adaptive Audio policy, and disable it using the policy settings. If you are using DDC version 1912, change the registry value of REG_DWORD EnableAdaptiveAudio to 0 in the following registry paths: Desktop VDA (Windows 10)--HKLM\Software\Citrix\Audio Server VDA (Server 2016\2019)--HKLM\Software\WOW6432Node\Citrix\Audio
Users are not able to share screen while using Microsoft Teams in Citrix VDA 2109 with Citrix Workspace app 2106 for Linux. The following new features from Citrix Workspace app 2108 and Citrix Workspace app 2109 are not supported:
Enhancement to logging--ThinOS does not provide the collectlog.py tool that lets you collect the log files from different folders.
Service continuity Support for Service continuity with Citrix Workspace Web Extension for Google Chrome Storebrowse enhancement for service continuity Global App Config Service (Public Technical Preview) Creating custom useragent strings in network request Feature flag management App protection--App protection component is not installed during Citrix Workspace app package installation in ThinOS.
Hence, the App protection feature is not supported in ThinOS. If you continue to enable App protection for Citrix delivery group, you cannot see the published resources in thin client. This limitation is a known issue in ThinOS. In Citrix Workspace app for Linux, the published resources can be seen, however, if you try to launch protected resources, the client displays a warning message.

Cisco WebEx Meetings optimization for VMware Horizon limitations
If you hot-plug the thin client, the thin client may stop responding during meetings. If you use the integrated microphone on the Wyse 5470 and Wyse 5470 All-in-One thin clients, there can be echo. The EagleEye mini camera does not work in WebEx Meetings.
HID fingerprint reader updates
HID Fingerprint Reader package is updated to 210217.11. This package resolves the issue where the ICA session does not launch after you upgrade Citrix Workspace app version 2106 to version 2109 or if you uninstall and reinstall Citrix Workspace app version 2109.
NOTE: Dell Technologies recommends that you disable Enable HID Fingerprint Reader before you upgrade the HID fingerprint reader package, and then enable it again after you upgrade the package. The HID fingerprint reader does not work in the ICA session without first disabling the Enable HID Fingerprint Reader option before you upgrade HID fingerprint reader package. If the HID fingerprint reader does not work in the ICA session, disable Enable HID Fingerprint Reader from Advanced > Session Settings > Global Session Settings in the Admin Policy Tool or Wyse Management Suite policy settings, and save the setting changes. Enable the Enable HID Fingerprint Reader option again, before you log in to the Citrix server.
Cisco WebEx VDI update
Cisco WebEx VDI package version is updated to 41.10.0.20213.1.
