Tosca client patch notes for 2026.1 LTS

This topic is all about patches for the 2026.1 LTS version of the Tosca client.

Keep in mind that Tosca patches are cumulative: the latest patch always contains the latest fixes and those of previous patches. This means you only need to install the latest patch to get all fixes for this Tosca version.

Installation

To install the Tosca patch, follow these steps:

  1. Download Tosca 2026.1.2 (opens in new tab) from the Tricentis Support Hub. Please note that you must be signed in with your Tricentis Support Hub credentials to see the download.

  2. Unzip the download package. Then, trigger the patch process:

    • For attended installation, run the executable file.

    • For unattended installation, run the command "Tricentis Tosca 2026.1.2 LTS.exe" /s /qn.

    Depending on your system environment, you may need to run as an administrator.

  3. The patching process installs new versions of all .dll.config files, which means the patched version overwrites the settings of the previous installation.

    To restore the settings to your needs, perform these actions:

    • Go to %TRICENTIS_ALLUSERS_APPDATA%\ConfigBackup<timestamp>\ToscaCommander, where you'll find backups of the old files.

    • Manually update the new versions of the .dll.config files with the information from the backups.

Only use your backup files as a reference.

  • Don't replace any new version files with your backup files.

  • Don't paste the entire content from your backup files without checking for differences between settings in the new and the old version.

New features

This section lists new features that we've added.

Tosca MCP Server: Enabled by default (since patch 2)

The Tosca MCP Server Addin is now enabled by default. You no longer need to enable it manually before you connect your AI assistant.

Data Integrity Connection Manager: New AI access setting (since patch 2)

The new Allow AI queries option in the Connection Manager controls AI access to your Data Integrity connections. Turn it on for each connection where AI agents may read data. This way, you can protect sensitive data from AI agents.

Tosca Cloud integration: Extended upload functionality (since patch 2)

With patch 2, we've extended our upload functionality:

New ENV expression for environment variables (since patch 2)

The new {ENV[<variable name>]} expression reads an environment variable at runtime. For example, in a TBox Set Buffer step, {ENV[username]} returns the signed-in Windows user's name. Use the new expression instead of any workarounds to buffer environment variables. We plan to end support for these workarounds in a future release, so switch to the ENV expression now to keep your tests working.

API Engine 3.0: HTTP/2 support (since patch 2)

You can now use the HTTP/2 protocol for your API test cases' web service connections. HTTP/2 reduces latency because it sends multiple requests over a single connection.

Unattended Execution: Microsoft Entra ID authentication (since patch 2)

You can now use a Microsoft Entra ID account to authenticate Remote Desktop Protocol (RDP) sessions for Unattended Execution. Agent machines need additional group and security policies for this authentication method. Active Directory and local accounts continue to work as before.

Model Context Protocol integration: New functionality (since patch 1)

With patch 1, we're introducing the Model Context Protocol (MCP) integration. MCP  is an open standard that connects AI assistants to external systems. With the Tosca MCP Server, AI assistants can access your Tosca workspace and help you create, organize, update, use, and run test assets.

Tosca Cloud integration: Extended upload functionality (since patch 1)

You can now upload TestCase-Design assets, like TestSheets and TestCase Templates.
