- CL-32 features added: - Hardware revision detection - v0.3 and v0.4 keyboard - v0.4 power supply - Inlined epd library (was a module) and made changes to the device definition (don't do full update after 5 small updates) - Statusbar: add support for inverted colors - e-paper driver improvements and warning fixes - Implemented gpio_controller_get_level() - Keyboard support improvements (unicode for tca drivers)
