Cendio are proud to present ThinLinc 4.21.0, with more than 100 enhancements and fixes. The most prominent changes are:

  • ThinLinc Web Access now supports the OpenID Connect authentication protocol. This enables organizations to delegate authentication to solutions like Keycloak or Microsoft Entra ID, allowing convenient single sign-on, and more flexibility in authentication methods and policy.

  • ThinLinc session logs are now in the system journal instead of in xinit.log in the ThinLinc session directories. This avoids multiple log locations for modern Linux systems, and gives more flexibility when analyzing logs.

  • It is now possible to configure the ThinLinc client with mandatory settings on managed endpoint devices. These settings will be forced and cannot be overridden by the user.

  • The Linux ThinLinc client now supports 64-bit ARM (ARM64), replacing the previous 32-bit ARM client. This improves compatibility with modern ARM hardware and operating systems.

  • The platform requirements for the ThinLinc client on macOS have been raised. It now requires macOS Ventura (version 13) or newer. Users on older versions of macOS will need to upgrade their operating system to use this version of the ThinLinc client.

Things to know before the upgrade

On the server side, ThinLinc 4.21.0 introduces two new restrictions that are worth keeping in mind before you upgrade:

  • The communication between ThinLinc nodes is now version checked. Before ThinLinc 4.21.0 it was possible to partially upgrade the nodes in a cluster. While such partial upgrades sometimes worked, they have been a source of hard-to-troubleshoot issues in the past. The recommended upgrade procedure is described here:

  • It is no longer possible to combine license files issued for different subscriptions in a single cluster. If you have combined licenses from different subscriptions up until today, contact support@cendio.com before upgrading and we will help you reconcile your subscriptions.

As always, we recommend reviewing the release notes before upgrading.

A detailed description of this release is available here:

The client and server software can be downloaded directly from our web page. The software is completely free for up to 10 concurrent users.
