This version of libDaisy and greater will be compatible with any version of the Daisy bootloader, meaning you won't have to update the bootloader on your product if you want the latest changes to libDaisy.
However, for newer versions of the bootloader, you must use a compatible version of libDaisy.
- Daisy bootloader v6.0 and up will only be compatible with libDaisy v5.3 and up.
