## What’s New

- **Integration of DRM License Cipher Solution**

  - Added support for the **DRM License Cipher**, a robust security enhancement that prevents unauthorized license requests initiated by key extraction tools and other malicious actors.

  - This feature helps ensure that DRM license responses are issued **only to authenticated clients** by encrypting the license challenge and verifying the integrity of the request on the server side.

- **Brand Transition to DOVERUNNER**

  - Updated the product branding from **‘PallyCon’** to **‘DOVERUNNER’**, reflecting the company’s new identity and unified service offerings across content security and application protection solutions.

  - The change includes updated namespaces, documentation, and logo assets.

  - Existing functionality remains fully compatible, with no breaking changes for current integrations.
