  *
+ *  <b>All</b>
+ *    - LUFA projects must now give the raw input clock frequency (before any prescaling) as a compile time constant "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().
+ *
+ *  <b>Device Mode</b>
+ *    - The NO_CLEARSET_FEATURE_REQUEST compile time token has been renamed to NO_FEATURELESS_CONTROL_ONLY_DEVICE, and its function expanded
+ *      to also remove parts of the Get Status chapter 9 request to further reduce code usage. On all applications currently using the 
+ *      NO_CLEARSET_FEATURE_REQUEST compile time token, it can be replaced with the NO_FEATURELESS_CONTROL_ONLY_DEVICE token with no further
+ *      modifications required.
