I couldn’t stand the idea of not having functional SD card this year, so there goes Owlsy v24.0
- SD card support, finally! Please see SD usage info for explanation about reading files from SD card.
- SD card browser menu
- Option to reboot device added to system menu
Bootloader additions:
- Extra checks for making sure that hardware used for bootloader and firmware match
- Additional code for breaking reboot cycle in case of boot failure
Naturally both Daisy Patch and KXMX bluemchen 
are supported.
