Added CDC_Host_Flush() function to the CDC Host Class driver to flush sent data to the attached device.

Simplified the USB.h master include file's target validity checks.

Better checking of whether a packet is received in the RNDISEthernetHost Class driver demo - show busy LED status while packets are being printed out.

Make the RNDISEthernetHost Class driver demo print out incomming packets from the attached RNDIS device.

Make MIDI device demos also turn off the on board LEDs if MIDI Note On messages are sent with a velocity of zero, which some devices use instead of Note Off messages (thanks to Robin Green).

Fix RNDIS Device Class driver - RNDISConstants.h has moved out to the Common Class driver directory.

Fixed all Class drivers to ensure they have appropriate guards on each function to ensure the device is enumerated before running, fixed error codes on all guards to return "DeviceDisconnected" where possble.

Renamed HOST_SENDCONTROL_DeviceDisconnect enum value to HOST_SENDCONTROL_DeviceDisconnected to be in line with the rest of the library enum error codes.

Added new RNDISHost Host LowLevel demo. Fixed misnamed Pipe_SetPipeToken() macro for setting a pipe's direction. Fixed CDCHost failing on devices with bidirectional endpoints.

Fixed host state machine not enabling Auto VBUS mode when HOST_DEVICE_SETTLE_DELAY_MS is set to zero.

Fixed broken USB_GetNextDescriptor() function causing the descriptor to jump ahead double the expected amount.

Fixed Pipe_IsEndpointBound() not masking the given Endpoint Address against PIPE_EPNUM_MASK.

Added new ReportType parameter to the HID Device Class driver CALLBACK_HID_Device_CreateHIDReport() callback to indicate the report type to generate.

Fixed incorrect values for REPORT_ITEM_TYPE_* enum values causing corrupt data in the HID Host Parser.

The incomplete StandaloneProgrammer project now uses Host and Device Mass storage classes, so that program data can either be loaded onto the device's Dataflash storage, or read off an attached USB memory stick.

The USB target family and allowable USB mode tokens are now public and documented (USB_CAN_BE_*, USB_SERIES_*_AVR).

The SCSI_Request_Sense_Response_t and SCSI_Inquiry_Response_t type defines are now part of the Mass Storage Class driver common defines, rather than being defined in the Host mode Class driver section only.

The USB_MODE_HOST token is now defined even when host mode is not available.

Added missing CDC_Host_CreateBlockingStream() function code to the CDC Host Class driver.

Removed code to zero reports between two keyboard reports with differing number of pressed keys, as this relied on non-standard OS behaviour.

Fixed Endpoint_Write_Control_Stream_* functions not sending a terminating IN when the given data length is zero.

Fixed LowLevel Keyboard demo not saving the issued report only after it has been written to the endpoint.

Added support for multiple keyboard keycodes in a single report to the LowLevel and ClassDriver Keyboard demos.

Add new (incomplete) StandaloneProgrammer project, using the ELM Petite FAT library to read files stored on the board's dataflash by the host.

Change device demos which use the joystick to use the natural UP, DOWN, LEFT, RIGHT ordering in all demos when checking the joystick's position.

Corrected the name of the misnamed USB_GetDeviceConfigDescriptor() function to USB_Host_GetDeviceConfigDescriptor().

Update CDC Class Driver character stream functions to use the correct avr-libc return codes for errors and EOF.

Fix pointer arithmetic on void byte buffers by explicitly typecasting the buffer pointers to uint8_t* before altering them.

Added new stream creation function to the CDC Class drivers, to easily make standard streams from CDC Class driver instances.

Make Mass Storage device Class driver accept resets at any time, rather than just after a command block has been processed.

Remove the HID device parser from the boot protocol Keyboard/Mouse demos.

Remove dependancies from the LowLevel demos to the ClassDriver demos, since the use of ClassDriver headers now outputs an error when NO_STREAM_CALLBACKS is used.

Make Low Level host demos use void pointers for the configuration descriptor, to prevent warnings when passed to the altered configuration descriptor parsing routines.

Added preprocessor checks to give a human readable error when the class drivers are used when the incompatible NO_STREAM_CALLBACKS compile time option is used.

Add optional double-banking support to the Device mode Class Drivers, on a per-endpoint, per-interface level.

Added new Printer Host mode ClassDriver demo.

Added table of supported classes and modes to the main USB Class Driver documentation.

Fixed HID report parser collection paths invalid due to misplaced semicolon in the free path item search loop. Increased the default number of collection paths allowable by the parser.

Add some missing documentation to some of the library demos.

Update DevChapter9.c - use the Endpoint_ClearStatusStage() function where possible to reduce code size and (potentially) allow for centralized status stage timeouts.

Fix Joystick device demo HID descriptors - buttons should be placed outside the Pointer collection.

Add new manual pages detailing the advantages of LUFA over the official Atmel USB AVR stack, and reasons why LUFA should be used over a built-from-scratch USB stack.
