Changelogs

TSplus Remote Access 19.30.5.12 consolidates all improvements and fixes from prior releases, hardens security, and adds streamlined deployment options for the Virtual Printer.

The Virtual Printer is a major TSplus Remote Access feature that allow to print jobs from a remote session and redirects them to the local printers, eliminating physical printer dependencies in virtual environments. As a result, each local printer is mapped to a corresponding virtual printer in the RDP session.

This new MSI installer simplifies enterprise deployment by enabling silent installations via Group Policy, SCCM, or scripts, reducing administrative overhead and ensuring smooth Virtual Printer client rollout across multiple machines.

• To install: msiexec /i Setup-VirtualPrinter-Client.msi /qb-

• To uninstall: msiexec /x Setup-VirtualPrinter-Client.msi /qb-

Improvements

• Providing MSI installer for VirtualPrinter client (available in tsplus\UserDesktop\files\addons folder).

• Improved HTTPS redirection configuration: when the HTTPS port is changed, HTTP to HTTPS redirection will now update automatically to the correct port, preventing client connection errors after port modifications.

• Compatibility: TSplus is compatible with Windows 11 26H1 latest preview updates, maintaining seamless operation on cutting-edge OS builds.

• HTML5 (v8.89): It is now possible to disable old TLS protocols or ciphers by server instance (see FAQ: /software/html5/faq.html#answer_72), offering granular security control per deployment.

• HTML5 (v8.89): For forwarded RDP connections, the iterations of TLS detection can be limited by setting ssl_rdp_underflow_max_iterations parameter in settings.bin (default: 10), optimizing performance in high-latency scenarios.

• HTML5 (v8.89): Security improved by strengthening control over X-FORWARDED-FOR header misuse, mitigating potential proxy-based attacks.

• Fix vulnerability by updating the log4net dependency to version 3.3.1, addressing known security issues in the logging library.

Fixes

• Fixed regression with "All users" applications assignation, ensuring reliable group-based app distribution across sessions.

• Connection Client (v126): Hardened the update mechanism to avoid occasional update failures, ensuring reliable auto-updates for end-users.

• Admin Tool > Advanced: Changing a configuration from one custom value to another is now correctly handled, preventing data loss during tweaks.

• Admin Tool: Preventing exception when restarting Web Server, enabling smooth service restarts without crashes.

With this version, we have put a strong focus on performance, especially for large-scale systems.

As a reference, we always kept in mind the use case of “100 servers - 1000 applications”.

The goal is to ensure great performance under such conditions.

Now, for users who have 1000 applications assigned, opening a session is smooth.

Also, a fix has been implemented for Floating Panel and Application Panel, with adding scrollbars when assigned apps are too numerous to be all displayed in the form.

A new Performance section has been added under Advanced Settings:

• “Disable Per user services” and “Enable high FPS frame rate” are existing settings, moved from Sessions > Session Management settings

• ⁠"Prefer hardware GPU" is an existing advanced setting, originally in "Session" section

• “Enable Application Assignation cache” greatly improves performance for users with many assigned applications. The default value is “Let the system decide” (it enables caching automatically when more than 25 applications are used in Remote Access) but you can set it to “yes” or “no”

• Other settings may improve performance in certain cases, depending on how your servers are used. Please read each setting’s description carefully before modifying its values

Here is the full changelog from the last 2 versions (v19.4.9 and after)

Improvements:

• Connection client: added missing langs for translations

• Compatibility: TSplus is compatible with Windows 11 26H1 latest preview updates

Thank you for reading this changelog, and thank you for the feedback you regularly provide ; it makes our products better and gives you a better experience!

Improvements

Web Portal 2026 with SSO (beta)

Web Portal 2026 with SSO is now available as a beta feature. Try it now from AdminTool > Web > Web server, check “Enable Web Portal 2026 for SSO” option and click “Save ans Restart Web server” to apply the change. We are eager to hear your feedback!

Important: This feature is Beta and should not be deployed on production servers.

Compared with the previous Web Portal, this implementation provides higher reliability and better performance under load. Plus, it allows:

• Advanced SSO capabilities, supporting Windows Integrated Authentication (Negotiate / Kerberos / NTLM) and third-party identity provider integration (currently SAML)

• Stronger security controls, with built-in anti-forgery protections, endpoint rate limiting and modern authentication and cookie/session controls

Its architecture will allow us to easily address any potential security audit feedback. It is also a more accessible product through recommendations and improved contrast.

Printing experience improvements

We aim to deliver a better printing experience through our Remote Access solution. To that end, we are rolling out a series of targeted improvements designed to enhance the usability of both Universal Printer and Virtual Printer. Here are the first enhancements we are releasing:

• A dedicated advanced settings section for the Universal Printer

• The installed version of Virtual Printer is displayed on the AdminTool > Printer page

Thank you for your continued trust in TSplus Remote Access. We sincerely appreciate you taking the time to read this and keep pushing it forward with us!

Improvements

Web Credentials synchronization across infrastructures

The Web Credentials feature now includes automatic synchronization of local configuration files to a shared remote folder.

This enhancement is particularly useful for large organizations running multiple TSplus Remote Access farms. It ensures consistent user authentication configurations across all servers of the farms, eliminating manual file management and reducing configuration drift between environments.

Web Credentials let you simplify and secure remote access by allowing users to sign in with a business-specific identifier, such as their email address or a PIN code, instead of a Windows username and password.

This approach hides the underlying Windows account details, reducing exposure and simplifying the login process for end users.

See https://docs.tsplus.net/tsplus/web-credentials

Expanded Windows 11 compatibility

TSplus Remote Access is now fully compatible with the latest versions of Windows 11, including editions 26H1, 25H2, and 24H2 preview builds.

We are happy to announce the release of Remote Access v18.50.9.9.
The release includes a new important feature for your farm controller.

Indeed, you will now be able to easily publish "virtual" applications on your farm controller, which are not available locally (or simply installed) but on one or more of your configured applications servers.

Before you needed before adding the app to go fetch the application path by connecting to your application server farm (using rdp for example), which looses the icon, or copy the application file directly and recreate the directory structure in your farm controller.

Now you just need, in the "Add application" form, to click on the new "Search on application server files" button to open a new application server file browsing form. Then simply double click on your application server, navigate to your application folder and select your application. This will retrieve the path on your application server, as well as its icon.

Important: the file navigation on application servers using the form only works for application servers using the current latest version of Remote Access (so version >= 18.50.9.9)

We are happy to announce the release of the "Applications" section revamp of Remote Access!

In the new Applications section, you will now always have two panels:

• one on the left where you select items (such as applications)

• one on the right where you assign entities (such as users/groups) to the selected items by ticking checkboxes of these entities

The goal is to simplify the assignment process as much as possible, as well as improving its visualization. As a result, a "swap" button which allow you to change the "select panel" with the "assign panel" has been added. This means that you will be able to quickly:

• assign users/groups to applications (default view) or if you swap:

• assign applications to users/groups

Important : the new interface allow multi selection (no need to do assignation one user/application at a time anymore), meaning you can

• assign one or more applications to one or more users for example, by selecting all the applications the users needs on the left, and tick all their user name to the right

• assign multiple users/groups to one or more applications, by selecting all the users/groups you want on the left, and assign them all the applications they need by ticking the application names on the right

In order to make the assignation process more manageable when there is lots of published applications and/or assigned users/groups, on both panels have been added:

• a search box

• a sorting button

• a filtering button

Finally, lots of "natural" actions have also been implemented to try matching with the user experience you have on the Windows explorer, making one's life easier. Basically, you will now be able to:

• Rename application/folder with pressing F2 or clicking 2 times on an application icon

• Create new folder via the new button "create new folder" which will add an empty application folder that you can rename and use afterwards

• Delete multiple applications/folder, just select the applications/folders you want to delete and press "Del" or click on "Delete"

• Move one or more applications to a specific folder by drag/dropping it on the folder

• Reorganize applications/folders by using the new "Organize" button (previously it was a left and right arrow), once clicked, just select the applications/folders you want to reorganize and drag/drop them to the proper location in the list

• Drag/drop a file from the windows explorer to the AdminTool to add it as a new application
