VOID OS 1.0.152 includes software from other projects. Each part keeps its own licence; VOIDOSS does not claim ownership of it. The licence texts are shipped inside VOID OS (ABOUT VOID → LICENSES, runtime/qt/licenses, /usr/share/doc) and repeated here. The source code below is offered to all users at no charge, from the same server as VOID OS. The checksums of every file are in SHA256SUMS.

Notice under The Qt Company GPL Exception 1.0: VOID OS runs its interface with Qt’s QML runtime tool (runtime/qt/bin/qml), licensed under the GPL 3.0 with that exception. The entire source code of the tool is offered to all users on this page (Qt 6.11.1 source, below).
