Increase timeout of Mass Storage and Still Image host commands to 10 seconds (up from 5) to account for slow-processing devices.

Added brace guards to macros with parameters to prevent unintended changed evaluation of the macro expression.

Minor code cleanups (remove redundant comments, fix spacing, etc.).

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).

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 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.

Fix doxygen documentation - doxygen was getting confused on the variable-length ATTR_NON_NULL_PTR_ARG() macro used on  function prototypes and was generating many return types for several functions in the documentation (thanks to David Lyons).

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.

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

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.

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

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.

Make HID device class driver ignore the previous HID report comparison buffer when the user sets it to NULL, disabling automatic report comparisons. Update HID device class driver documentation giving previous report buffer limitations.

Moved USBtoSerial demo the Projects directory, as it is simply an expanded CDC demo. Added const qualifier to Endpoint/Pipe stream write routines.

Fix AudioOutput and AudioInput class driver demos' descriptors -- incorrect value was being supplied in the audio descritors field giving the number of discrete audio formats the device supports.

Fix up demo documentation device compatibility list to be as general as possible to reduce changes required as Atmel releases more devices within the same USB AVR series.

Make MouseHost and KeyboardHost ClassDriver demos use the HID Class driver's structures for the boot protocol Mouse/Keyboard report data, rather than rolling their own.

Make unfinished device mode applications use the VID/PID reserved for LUFA development devices.

Simplify AudioOutput demos, to reduce the number of cycles needed to process each incomming sample.

Changed Audio Class driver sample read/write functions to be inline, to reduce the number of cycles needed to transfer samples to and from the device (allowing more time for processing and output).

Fixed ClassDriver AudioOutput demo not selecting an audio output mode.

Removed mostly useless "TestApp" demo, as it was mainly useful only for checking for sytax errors in the library.

MIDI device demos now receive MIDI events from the host and display note ON messages via the board LEDs.

Added beginnings of a MIDI class bootloader.

Add new error condition to the HID Report Parser for when a report is parsed but no unfiltered items are encountered (i.e. nothing of interest in the device report). Make all host HID "WithParser" demos print the new error condition.

Move Dataflash operational checking code out from SCSI.c into the DataflashManager.c in the Device mode Mass Storage demos.

Add new MouseHostWithParser and KeyboardHostWithParser Host Class driver demos.
