The latest revision of those files can be found here.

- MAJOR versions in this context mean a breaking change to the external interface of the hardware like different connectors or functions. - MINOR versions contain changes to the hardware that only affect the inner workings of the circuit, but otherwise the performance is unaffected. - PATCH versions do not affect the schematics or invalidate older bill of materials. These changes may include updated…
