Release Notes

Browser content redirection proxy setting—If you use the browser content redirection proxy settings, enter a valid proxy
address and port number in the browser content redirection proxy configuration policy. Citrix Workspace app follows the server
fetch and client render mechanism. It fetches URL from VDA and redirects the browser content from the thin client.
For more information about Browser Content Redirection, see the Browser Content Redirection article at docs.citrix.com.
For more information about how to enable Browser Content Redirection on ThinOS, see the Dell Wyse ThinOS Version 9.0
Administrator's Guide at www.dell.com/support.
Citrix HDX Adaptive transport (EDT)
ThinOS supports Citrix HDX Adaptive transport for Citrix Virtual Apps and Desktops. HDX Adaptive transport enables the ICA
virtual channels to automatically adapt to varying LAN and WLAN connections and improves the data throughput.
For more information about Citrix HDX Adaptive transport, see the Citrix documentation at docs.citrix.com.
For information about how to enable HDX Adaptive Transport, see the Dell Wyse ThinOS Version 9.0 Administrator's Guide at

HDX Adaptive Display V2
ThinOS supports the selective use of a video codec (H.264) to compress graphics during video playback in an ICA session. This
feature combines the H.264 mode and Thinwire Compatible mode for a better user experience.
For more information about HDX Adaptive Display V2, see the Citrix documentation at docs.citrix.com.

Citrix two-factor authentication
ThinOS supports Citrix two-factor authentication that authenticates the identity of the user twice before granting access,
adding an extra level of security.
For local authentication, there must be a user profile that is created in the Citrix ADC database. For external authentication, the
username and password that is entered must be the same as registered in the authentication server. After a successful
validation of the username and password, the user is requested for another level of authentication.
ThinOS supports LDAP, RSA+LDAP, SMS Passcode, DUO, OKTA, and Azure MFA authentications by default. The user must only
provide the Citrix ADC gateway address.
To log in to NetScaler Gateway that uses LDAP with RSA authentication, you must select LDAP+RSA in the Wyse
Management Suite policy. You can also go to Admin Policy Tool and configure the NetScaler/ADC Authentication Method
option in the Citrix Broker Settings window.
For specific users who want to use Citrix ADC authentication methods, such as LDAP with MFA, it is recommended that you
configure the NetScaler/ADC Authentication Method with LDAP either using the Wyse Management Suite policy or the
Admin Policy tool.
Keyboard enhancements on Windows VDA
ThinOS supports the Unicode Keyboard Layout Mapping on Citrix Apps and Desktops. This feature enables you to use the
Unicode keyboard layout mapping for non-Windows Citrix Workspace app on the Windows VDA.
If you select a localized keyboard layout on the ThinOS local UI, the selected keyboard layout is not synchronized in the ICA
session. However, the client local keyboard layout is mapped to the existing language in the language bar of the session. For
example, if the existing language is English (United States) in the ICA session, and if you select German layout on the ThinOS
local UI, then the German language is not displayed on the session language bar. However, the English (United States) keyboard
in the ICA session works as a German keyboard layout.
NOTE:
When you select a localized keyboard such as German on the ThinOS local UI, you must not manually add the
language again in the ICA session. This is because the output of the manually added German keyboard can be disordered.
