* - LUFA projects must now give the raw input clock frequency (before any prescaling) as a compile time constant \c F_CLOCK,
* defined in the project makefile and passed to the compiler via the -D switch.
* - The makefile EEPROM programming targets for FLIP and dfu-programmer no longer program in the FLASH data in addition to the
* EEPROM data into the device. If both are to be programmed, both the EEPROM and FLASH programming targets must be called.
* - As the avr-libc macro has been corrected in recent avr-libc distributions, the SetSystemClockPrescaler() macro has been removed.
* Include <avr/power.h> and call clock_prescale_set(clock_div_1); instead on recent avr-libc distributions.

*
* <b>Library Demos</b>
* - The USBtoSerial demo now discards all data when not connected to a host, rather than buffering it for later transmission.
* - Most demos, bootloaders and applications have had their control request handling code corrected, to properly send the status
* stage in all handled requests. If you are using code based off one of the library demos, bootloaders or applications, you should
* update to the latest revisions.
*
* <b>Non-USB Library Components</b>
* - The ATTR_ALWAYSINLINE function attribute macro has been renamed to ATTR_ALWAYS_INLINE.
* - Custom board Dataflash drivers now require the implementation of Dataflash_SelectChipFromPage() and Dataflash_SendAddressBytes().

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