+ *      defined in the project makefile and passed to the compiler via the -D switch.\r
+ *    - The makefile EEPROM programming targets for FLIP and dfu-programmer no longer program in the FLASH data in addition to the\r
+ *      EEPROM data into the device. If both are to be programmed, both the EEPROM and FLASH programming targets must be called.\r
+ *    - As the avr-libc macro has been corrected in recent avr-libc distributions, the SetSystemClockPrescaler() macro has been removed.\r

+ *    - The NO_CLEARSET_FEATURE_REQUEST compile time token has been renamed to FEATURELESS_CONTROL_ONLY_DEVICE, and its function expanded\r
