* - Added new PROGMEM variant send functions to the CDC class host driver
*
* <b>Changed:</b>
+ * - Core:
+ * - The TWI peripheral driver's TWI_WritePacket() and TWI_ReadPacket() functions now takes a 16-bit Length rather than an 8-bit
+ * length, for longer transfers
* - Library Applications:
* - The CDC, DFU, Mass Storage and Printer class bootloaders will no longer run the user application if the application reset
* vector is blank (thanks to Alex Kazik)
