This release contains fixes/updates by @editicalu
- Use CMake instead of QMake as it is phased out.
- Update to Qt6, removing deprecated code.
- Use newer SVG images from the KDE project
Note: The packages for Linux and Mac do not contain the necessary Qt libraries in this release. They need to be installed separately. If that doesn't work, you can try one of the older versions or try to build from source for now.
