Dell ThinOS 2211, 2208, and 2205 Release Notes

Upgrade from ThinOS 9.1.x to later versions using Wyse Management Suite

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 new version of the 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.

   NOTE:To optimize security, application performance, and stability, a design change has been made in ThinOS 2205 when installing third-party applications, like Citrix Workspace App, VMware Horizon, and Microsoft AVD. Third-party applications released as part of ThinOS 2205 use a different shared library search path than older third-party package versions. Because of this optimization, third-party packages that are released before ThinOS 2205 are no longer supported with ThinOS 2205 or later versions. Install the latest version of the required third-party application after you upgrade to ThinOS 2205 or later versions.

   NOTE:There are chances that the ThinOS background might be in blue color and some features may not work. In this case, you have to reboot the device.
