This release:
- substantially improves fast loading of tapes on the Commodore Plus 4;
- improves the internal naming of options that became slightly opaque when exposed on the SDL command line — e.g. 'quickload' becomes 'accelerate-media-loading';
- corrects transitory framing errors when starting the ZX Spectrum; and
- moves from Qt 5 to Qt 6, correcting an OpenGL-related crash on the way.
