- Fixed crash when returning to Setup app (from any of the steps) - Fixed crash when returning to TimeDateSettings app (after locale selection) - Fixed GuiService inconsistent behaviour: now always perform operations async (e.g. to show/hide apps). This fixes crashes in some onHide() calls where onHide() might be called before onShow() was called. - Fix for incorrect WebServService path - Remove CYD-4848S040C SD card functionality, but added a GPIO fix for releasing 3-wire SPI pin sharing. - Fix for saving/loading settings for various apps
