- Add: Support for gauge element direction flipping (gslc_ElemXGaugeSetFlip) and improved redraw.
- Add: Support for GUIslice with LINUX mouse support in DRV_DISP_SDL* (eg. Raspberry Pi with HDMI display) using DRV_SDL_MOUSE_SHOW. Note that mouse dragging is not yet supported.
- Update: Configuration (GUIslice_config.h) updated to use more consistent notation with #define. Added GUIslice config guide (docs/GUIslice_config_guide.xlsx) to demonstrate example CPU / board / display configuration settings.
- Fix: Fixed error in DRV_TOUCH_SDL mode
- Migration Notes (from 0.8.3):
  - The following #define should now use an explicit value (1 to enable, 0 to disable): ADAGFX_SPI_HW, ADATOUCH_I2C_HW, ADATOUCH_SPI_HW, ADATOUCH_SPI_SW, DRV_SDL_FIX_START.
