    /*
     *  The value of k_format_version determines whether the existing
     *  eeprom data is considered valid. You should only change this
     *  value under the following circumstances:
     *
     *  1) the meaning of an existing eeprom parameter changes
     *
     *  2) the value of an existing k_param_* enum value changes
     *
     *  Adding a new parameter should _not_ require a change to
     *  k_format_version except under special circumstances. If you
     *  change it anyway then all ArduPlane users will need to reload all
     *  their parameters. We want that to be an extremely rare
     *  thing. Please do not just change it "just in case".
     *
     *  To determine if a k_param_* value has changed, use the rules of
     *  C++ enums to work out the value of the neighboring enum
     *  values. If you don't know the C++ enum rules then please ask for
     *  help.
