openthinclient OS

Kernel update to 5.10 Update various hardware drivers to support new hardware. After package update or installation on the server, a prompt to restart appears on all thin clients. The boot server’s IP address is displayed on the thin client desktop. Associate the thin client hostname locally with the IP address obtained from DHCP. 127.0.0.1).

USB permissions

Increase minimum storage size to 8 GB (affects devices that are being reflashed)

Citrix

The Citrix client has been updated to the current version 2106 — Citrix Release Info Support for multiple autostart name patterns. Restore support for Grundig devices. Additional options now let administrators limit generic USB pass-through to specific devices. Added option to select USB serial ACM adapters.

Teams

The standalone Teams client has been updated to version 1.4.00.13653. Specify an HTTP proxy and any other command-line options.

Zoom

The standalone Zoom client has been updated to version 5.7.1. The language of the Zoom interface matches the language of the openthinclient OS.

Management Server

Simplify boot settings in the hardware type to "Fast and Secure". Fix: Assignments to user groups now work
Fix: When naming objects, the system now validates characters. / is now correctly displayed as an error. Improvements for ThinClient management:

The thin client overview list shows online status and MAC address. Filter the overview list by MAC and IP address. Use Wake-On-LAN for multiple thin clients in the overview list. The IP address of a thin client appears in the title bar; copy it to the clipboard with a mouse click. The title bar indicates whether the thin client is online or offline. Revise and improve display and storage of client logs.

Older log messages are now displayed Note for large installations: Up to 8 MB of log data per client is now stored in the Manager Home. Regularly delete old files:

Packages that have not been installed for more than 20 d are removed from the package cache. Delete error reports older than 20 d. Old logs are now reliably removed. Improved behavior for beta versions of client packages:

Beta packages appear under Available Packages only when Beta versions are selected. Beta packages are considered as updates only if the package in question is already a beta version (or if the management server itself is a beta version). Display a warning when installing beta packages. Improvements to the user interface, among other things:

The hostname and the optional description of the installation are displayed in the header. Display the specific type of an object in the title bar.
Improved display and positioning of the "Create New" button in overview views. When creating a new item, sort selection lists. All relevant assignments are displayed.

Known issues

openthinclient Manager

When renaming a hardware type used by a thin client, the save operation completes successfully, and the system displays an error message.

Active Directory integration

In the openthinclient Manager, the display names of the users are shown instead of the logon names. If the user ID for the login credentials for read access contains umlauts or special characters (non-ASCII), the thin client login requires a compatible character set.

Citrix

The Citrix Receiver provides a list of known issues from the manufacturer (Release Info).

FreeRDP

FreeRDP is under continuous development. The developers collect all known issues in the GitHub Issue Tracker.
When using Terminal Server ≤ 2008R2, use rdesktop instead of FreeRDP.
