   *    of device configurations can be defined statically
   *  - Removed VBUS events, as they are already exposed to the user application via the regular device connection and disconnection events
   *  - Renamed and altered existing events to properly separate out Host and Device mode events
+  *  - All demos switched over from GNU99 standards mode to C99 standards mode, to reduce the dependancies on GCC-only language extensions
   *
   *  <b>Fixed:</b>
   *  - Changed bootloaders to use FLASHEND rather than the existence of RAMPZ to determine if far FLASH pointers are needed to fix
