Qt WebEngine Licensing

The Qt specific parts of the Qt WebEngine module are dual-licensed under Commercial and GNU Lesser General Public License (LGPLv3). In addition, the module contains code licensed under LGPLv2.

The module includes a snapshot of Chromium. As such, users need to respect the licenses of Chromium, and third-party code included in Chromium. The arguably most restrictive license to be respected by all users is LGPLv2.1.

Third party licenses included in the sources are:
