+ * <b>Non-USB Library Components</b>
+ * - The Dataflash board driver stub file has changed, as dataflash functions previously located in the internal
+ * Dataflash driver of the library have now been moved to the individual board files. Existing drivers can
+ * copy-paste the new functions from the board Dataflash stub driver.
*
* <b>USB Core</b>
* - A new USB driver source file, Drivers/USB/LowLevel/Device.c now exists. This source file should be added to all project
- * makefiles using the USB driver of LUFA.

*
* <b>Device Mode</b>
* - The USB_Device_IsRemoteWakeupSent() macro has been removed, as the remote wakeup request is now fully handled by the
* enhanced \ref USB_Device_SendRemoteWakeup() function. Existing code may now discard any checks to USB_Device_IsRemoteWakeupSent().
* - The USB_Device_IsUSBSuspended() macro has been removed, as it is obsolete. Existing code should compare \ref USB_DeviceState
* to see if it the device is in the \ref DEVICE_STATE_Suspended state instead.
+ * - The \ref CDC_Device_ReceiveByte() function has changed, and now returns a signed 16-bit integer, with -1 indicating no data was
+ * received. This allows for more efficient coding, as a call to \ref CDC_Device_BytesReceived() is no longer needed if the exact
+ * number of queued bytes received is not needed.
+ *
+ * <b>Host Mode</b>
+ * - The \ref CDC_Host_ReceiveByte() function has changed, and now returns a signed 16-bit integer, with -1 indicating no data was
+ * received. This allows for more efficient coding, as a call to \ref CDC_Device_BytesReceived() is no longer needed if the exact
+ * number of queued bytes received is not needed.
+ * - The \ref CDC_Host_USBTask() now calls \ref CDC_Host_Flush() automatically, flushing any queued data to the attached device. Manual
+ * flushing of the interface is no longer needed if the flushes should be in sync with calls to \ref CDC_Host_USBTask().

* <b>Host Mode</b>
* - The MIDI Host Class driver send and receive routines now operate on packed events, where multiple MIDI events may be
* packed into a single USB packet. This means that the sending of MIDI events will now be delayed until the MIDI send
- * pipe bank is full. To override this new behavior and revert to the previous behavior, the user application may manually

* - The Pipe_IsEndpointBound() function now takes the endpoint's direction into account, by checking if the MSB of the endpoint's address
* is set to denote IN endpoints. If the previous functionality where the direction is to be discounted is required, mask the endpoint
