- Updated LVGL from 8.3 to 9.0 (removed example/docs/demo folders) - Updated esp_lvgl_port to current status of the `lvgl9` branch on `esp-bsp`: https://github.com/espressif/esp-bsp/tree/lvgl9 - Updated all boards and drivers - Removed `libs/lv_drivers` subproject as SDL is now supported by LVGL directly (although keyboard input seems broken) - Updated `libs/lv_screenshot` - Fixed the way `tt_statusbar` widget works due to behaviour change in LVGL - Updated other lvgl code
