They are not "versions" or "branches" of the software development, the
hardware for each one is different.
+None of the old ones are actually supported as the core code may have changed

+(host/scialys_decode) used to decode data sent over UART.
Refer to the main README file (at the root of the core support git repository)
for more information about building and flashing.
