+ *  <b>Device Mode</b>
+ *    - The definition of the Audio class \ref USB_Audio_Descriptor_Format_t has been altered, to remove the fixed singular
+ *      audio sample rate in the descriptor definition, and to rename the \c SampleFrequencyType to the more appropriate
+ *      \c TotalDiscreteSampleRates. Existing applications will need to add an array of \ref USB_Audio_SampleFreq_t elements
+ *      immediately following any \ref USB_Audio_Descriptor_Format_t descriptors, and insert the appropriate sampling rates
+ *      supported by the device, as well as rename the descriptor elements to match the updated element names.
+ *    - The device mode Audio class driver now requires a new user application callback, \ref CALLBACK_Audio_Device_GetSetEndpointProperty().
+ *      Existing applications must implement this new callback, however if multiple sample rates or pitch control is not used,
+ *      this function may be hard-coded to always return false for previous behaviour to be retained.

+ *  <b>Non-USB Library Components</b>
+ *    - The TWI driver \ref TWI_StartTransmission() function return type has now changed, so that the function returns an
+ *      error code from the \ref TWI_ErrorCodes_t enum instead of a boolean success flag. Existing code must now check
+ *      against the \ref TWI_ERROR_NoError return value for success instead of a boolean \c true value, or it will not function
+ *      correctly.
+ *    - The Serial Stream driver has been removed, and its functionality rolled into the regular serial driver. Existing code
+ *      should remove references to the \c LUFA_SRC_SERIALSTREAM module in their makefiles, include the regular Serial driver
+ *      header instead and call the regular \ref Serial_Init() function followed by the new \ref Serial_CreateStream() function
+ *      with a \c NULL parameter.
+ *    - The \ref Serial_ReceiveByte() function has changed, and now returns a signed 16-bit integer, with -1 indicating no data was
+ *      received.
+ *    - The TWI driver \ref TWI_Init() function now expects additional prescaler and bitlength parameters. See the function
+ *      documentation for more details.
+ *    - The name postfix on all driver modules to turn off and disable that module has been changed from *_ShutDown() to *_Disable().
+ *      Rename all references to these functions to use the new function names.

+ *  <b>USB Core</b>
+ *    - By default, unordered Endpoint and Pipe configuration is now allowed once again, via the previous workaround of
+ *      reconfiguring all Endpoints/Pipes in order each time a new Endpoint/Pipe is created. To minimize the compiled program
+ *      size, the new \c ORDERED_EP_CONFIG compile time option may be defined in the project makefile to restrict the ordering
+ *      in exchange for a smaller compiled binary size.
+ *    - The previous F_CLOCK symbol, required in the project makefile, has been renamed to F_USB. This is due to the previous name
+ *      being far too generic for use in future architecture ports, where multiple clock domains are used.
+ *
+ *  <b>Device Mode</b>
+ *    - The Endpoint stream functions now all require a \c BytesProcessed parameter instead of the previous callback parameter.
+ *      This should be set to \c NULL to retain previous behaviour of the functions, or point to a location where the number of bytes
+ *      processed in the current transaction can be stored. If the \c BytesProcessed parameter is non \c NULL, each time the endpoint
+ *      bank becomes full and the packet is sent, the routine will exit with the new \ref ENDPOINT_RWSTREAM_IncompleteTransfer
+ *      error code to allow the user application to determine when to send the next chunk of data.
+ *    - The \ref CDC_Device_SendString() function now expects a null terminated string instead of an explicit length. Existing code
+ *      should use the new \ref CDC_Device_SendData() function, or remove the length parameter from the function call.
+ *    - The Endpoint_ResetFIFO() function has been renamed to \ref Endpoint_ResetEndpoint(), to make the API function names more
+ *      consistent. Existing applications using the old function name should simply replace it with a call to the new function name.
+ *    - The Endpoint_*_Byte() functions have been renamed Endpoint_*_8() to ensure they are correct across all architectures. Existing
+ *      code using these functions should replace the previous function names with the new function names.
+ *    - The Endpoint_*_Word() functions have been renamed Endpoint_*_16() to ensure they are correct across all architectures. Existing
+ *      code using these functions should replace the previous function names with the new function names.
+ *    - The Endpoint_*_DWord() functions have been renamed Endpoint_*_32() to ensure they are correct across all architectures. Existing
+ *      code using these functions should replace the previous function names with the new function names.
+ *    - The Device mode RNDIS class driver no longer stores the incoming and outgoing packets in the class driver instance; the user is
+ *      now expected to manually define a storage location for the packet data. Packets must now be sent and received manually via a call
+ *      to \ref RNDIS_Device_ReadPacket() and/or \ref RNDIS_Device_SendPacket().
+ *
+ *  <b>Host Mode</b>
+ *    - The Pipe stream functions now all require a \c BytesProcessed parameter instead of the previous callback parameter.
+ *      This should be set to \c NULL to retain previous behaviour of the functions, or point to a location where the number of bytes
+ *      processed in the current transaction can be stored. If the BytesProcessed parameter is non \c NULL, each time the pipe

+ *      error code to allow the user application to determine when to send the next chunk of data.
+ *    - The \ref PRNT_Host_SendString() and \ref CDC_Host_SendString() functions now expect a null terminated string instead of an explicit
+ *      length. Existing code should use the new \ref PRNT_Host_SendData() and \ref CDC_Host_SendData() functions, or remove the
+ *      length parameter from the function call.
+ *    - The Pipe_ClearErrorFlags() function has been removed, as the pipe error flags are now automatically cleared when the
+ *      \ref Pipe_ClearError() function is called.
+ *    - The Pipe_*_Byte() functions have been renamed Pipe_*_8() to ensure they are correct across all architectures. Existing code using
+ *      these functions should replace the previous function names with the new function names.

+ *    - A new USB driver source file, \c Drivers/USB/HighLevel/EndpointStream.c now exists. This source file should be added
+ *      to all project makefiles using the USB driver of LUFA, or the makefile should be updated to use the new module source
+ *      variables.
+ *    - A new USB driver source file, \c Drivers/USB/HighLevel/PipeStream.c now exists. This source file should be added to all
+ *      project makefiles using the USB driver of LUFA, or the makefile should be updated to use the new module source variables.
+ *    - The \c EVENT_USB_InitFailure() event has been removed, as the \ref USB_Init() function will no longer fail; if not USB mode is
+ *      specified, the controller will default to UID selection mode.
+ *    - The USB mode specifier constants have been moved into a new enum and renamed. Existing projects should use the equivalent
+ *      value in the new \ref USB_Modes_t enum.
+ *    - All class driver headers are now included as part of the standard \c LUFA/Drivers/USB/USB.h master dispatch header, and should
+ *      no longer be included separately. Class driver module source files must still be added as a separate module in the project's
+ *      makefile if used.
+ *
+ *  <b>Device Mode</b>
+ *    - Endpoints MUST be allocated in ascending order to ensure that bank corruption does not occur. Ensure that your user application
+ *      allocated endpoints in ascending order - or if your application uses the USB device mode class drivers, ensure that each instance's
+ *      endpoint indexes are not overlapped with other interface's endpoints.
+ *    - The signature for the \ref CALLBACK_USB_GetDescriptor() callback has changed, the \c void** \c const \c DescriptorAddress parameter is
+ *      now \c const \c void** \c const \c DescriptorAddress. Existing applications should update their callback signatures to match this, and
+ *      eliminate any casting of descriptor pointers to a non \c const pointer.
+ *    - The names of the class specific descriptor type defines in the USB Class drivers have changed - refer to the driver documentation
+ *      for each class driver for the new class specific descriptor type names.
+ *    - The \c ENDPOINT_DOUBLEBANK_SUPPORTED() macro is has been renamed \ref ENDPOINT_BANKS_SUPPORTED() and now returns the total number of
+ *      banks supported by the given endpoint. Existing code should switch to the new naming scheme, and test that the return value of the
+ *      macro is equal to or greater than 2 to regain the previous functionality.
+ *    - The \c EVENT_USB_Device_UnhandledControlRequest() event is now named \ref EVENT_USB_Device_ControlRequest() and fires before (not after)
+ *      the internal library event handlers. Existing code should rename the event handlers in the user application to match the new event
+ *      name, and should ensure that the new execution order does not affect the application's operation.
+ *
+ *  <b>Host Mode</b>
+ *    - Pipes MUST be allocated in ascending order to ensure that bank corruption does not occur. Ensure that your user application
+ *      allocated pipes in ascending order - or if your application uses the USB host mode class drivers, ensure that each instance's
+ *      pipe indexes are not overlapped with other interface's pipes.
+ *    - The \c PRNT_Host_SendData() function has been renamed to \ref PRNT_Host_SendString(). Existing applications should simply
+ *      replace all references to the obsolete function name with the new function name.
+ *    - The names of the class specific descriptor type defines in the USB Class drivers have changed - refer to the driver documentation
+ *      for each class driver for the new class specific descriptor type names.
+ *    - The Still Image Host class' function prefix has been changed from \c SImage_ to  \c SI_, to remain consistent with the rest of the
+ *      driver's enums, type defines and constants.

+ *
+ *  <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, \c Drivers/USB/LowLevel/Device.c now exists. This source file should be added to all project
+ *      makefiles using the USB driver of LUFA, or the makefile should be updated to use the new module source variables.
+ *    - The \c Drivers/USB/LowLevel/DevChapter9.c source file has moved to \c Drivers/USB/HighLevel/DeviceStandardReq.c - this should
+ *      be updated in all project makefiles, or the makefile should be updated to use the new module source variables.

+ *
+ *  <b>Device Mode</b>
+ *    - The \c 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 \c USB_Device_IsRemoteWakeupSent().
+ *    - The \c 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_Host_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().
