Handling License Key File Name and Environment Variable Name Changes in the 2025 Q1 Release

Environment

Product	Progress® Kendo UI® for jQuery
Version	2025.1.212

Description

Starting with the 2025 Q1 release, the following changes will apply to the license key file name and the environment variable used to store the license key:

• The name of the downloaded file with the license key changes from kendo-ui-license.txt to telerik-license.txt. This file is now used for the licensing of the entire Telerik and Kendo products portfolio.

• The name of the environment variable used to store the license key changes from KENDO_UI_LICENSE to TELERIK_LICENSE.

These are not breaking changes:

• Applications and CI/CD tools using the existing kendo-ui-license.txt file and KENDO_UI_LICENSE environment variable will remain fully functional.
• If a system or environment has both the new and the old license keys file and environment variables, the licensing mechanism will use the new ones.

Solution

Although the introduced changes are not breaking changes, the Kendo team recommends applying the following changes to avoid confusion caused by the different naming:

1. Update the @progress/kendo-licensing package to the latest version.
2. Remove the legacy license key file and environment variable (if using environment variables to store the license key):
   • kendo-ui-license.txt
   • KENDO_UI_LICENSE
3. Download a new license key file called telerik-license.txt.
4. If using environment variables or secrets:
   1. Create a new environment variable called TELERIK_LICENSE.
   2. Add the newly downloaded license key as a variable value.

Alternatively, only if you have an existing application or CI/CD environment where you cannot update the @progress/kendo-licensing package to the latest version: rename the downloaded telerik-license.txt file to kendo-ui-license.txt or copy its contents to the KENDO_UI_LICENSE environment variable.
