This release is mostly for stability, with almost no UI changes. They'll come eventually.
- Adds full support for version 3.0 of the repository spec. This allows list updating to be done more efficiently, though the improvements are likely not noticeable to humans
- Properly scans all appropriate directories for PNDs, including pandora/mmenu
- Ctrl+Q shortcut closes the GUI
- Will fail gracefully when encountering network connectivity errors, rather than acting like it's working
