Tosca Server patch notes for version 2026.1 LTS

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

Keep in mind that Tosca Server 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 Server version.

Installation

Tosca Server 2026.1 LTS patches support implicit installations and automatically transfer your configurations and settings to the patched version. The only exceptions to this are Exploratory Testing and Interactive Testing, where you need to back up and repopulate configuration files manually.

To install a Tosca Server patch, follow these steps:

  1. Download Tosca Server 2026.1.1 (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. If you use Exploratory Testing and/or Interactive Testing, back up their configuration files.

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

    • For attended installation, run the executable file.

    • For unattended installation, run the command "Tricentis Tosca Server 2026.1.1.exe" /s /qn.

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

  4. If you use Exploratory Testing and/or Interactive Testing, update the new version's configuration files.

  5. Open Tricentis Service Configuration and verify your settings. Then, select Save in any tab. This is an important step to finalize your patch.
