Fixes & Enhancements
- Changed the default DNS IP version to prioritize the IPv4 address.
- Supports WMS auto discovery using the IPv6 DHCP option.
- Supports the FIDO2 Security Key Management.
- Added support to display the firmware version of an external monitor.
Important Information
- From ThinOS 2408, ThinOS is updated to completely follow WMS Security Policy > TLS Security Level (default = 1). If your network environment requires a legacy OpenSSL version, then must change the TLS security level to 0, when updating to 2411. Otherwise, the device can lose its network.
- From ThinOS 2408, the VMware Horizon Session SDK package is no longer supported. It is recommended to upgrade ThinOS clients in the environment to the VMware Horizon Client SDK package to avoid issues.
- Do not power off your thin client until the installation is complete.
- If you are using ThinOS 8.6 or earlier versions of ThinOS 9.x, you must first upgrade to ThinOS 9.1.3129 or later versions before upgrading to ThinOS 2411.
- Before upgrading from ThinOS 9.x to later versions, ensure that your system is powered on, and the sleep mode is disabled on the system. If the system has entered the sleep mode, you must send the Wake-on-LAN command through Wyse Management Suite before using any real-time commands. To use the Wake-on-LAN command, ensure that the Wake-on-LAN option is enabled in the BIOS.
- You cannot boot into ThinOS 2411 (9.5.4070) or later versions when you perform the following operations:
1. Disable the onboard Network Interface Card (NIC), Trusted Platform Module (TPM), or Platform Trust Technology (PTT).
2. Clear TPM or PTT.
3. Reset BIOS to factory default settings.
- The upgrade may fail if the event log fails to install. In such an event, reboot the device and upgrade again.
- After upgrading to ThinOS 2411, all application packages that are released before 2205, Microsoft AVD package that is released before 2311, Zoom AVD, Zoom Citrix, and Zoom Horizon packages are removed automatically and cannot be installed again. You must install the latest application packages.
