## 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](https://www.telerik.com/account/your-licenses/license-keys) a new license key file called `telerik-license.txt`.

4. If using [environment variables](https://www.telerik.com/kendo-angular-ui/components/licensing/ci-services) or secrets:
   * Create a new environment variable called `TELERIK_LICENSE`.
   * 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.
