Add new HID_Device_MillisecondElapsed() function to the HID device Class driver, to move the burden of managing the Idle period of each instance to the library and not the user application.

Fix to HID device mode Class driver, so that new reports are compared against the old, and updated reports made within the idle period are sent immediately to the host.

Make all audio device Class Driver functions require a reference to the Audio class instance, so that the endpoint size can be checked (and to standardize the APIs).

Make LEDs more responsive in the AudioOutput device demos.

Set all CDC and MassStorage device mode demos (LowLevel and ClassDriver) to use the USE_INTERNAL_SERIAL feature, add compile time warnings for devices which do not have an internal serial.

Fix incorrect HWB button mask in the STK526 Buttons driver.

Fix redefinition warning when USB_DEVICE_ONLY is set on an AVR which does not support USB host mode.

Change project makefiles so that the current target settings and not just the board selection is printed during the build process.

Fix warning in AudioOutput demos when AUDIO_OUT_STEREO output mode is selected.

Make LowLevel AudioOutput demo work in the same way as the ClassDriver AudioOutput demo for LEDs output.

Changed AudioOutput demos to explicitly use timer 3 - the smaller USB AVRs where timer 1 was needed instead did not have the endpoint size neccesary for good audio throughput anyway.

Fix Benito documentation indicating erronously that the project used the HID USB class instead of the CDC class.

State information for class drivers is now zeroed out during enumeration (both in device and host mode) to ensure sane values after each enumeration. User code should no longer explicitly set state information as this is no longer preserved.

Added new Benito project, a simple modified USB-to-Serial bridge for the programming of AVRs using the official Arduino bootloader.

Ensure that the USB_DeviceState variable is properly set upon wakeup events, to the Addressed or Configured state as needed.

Add explicit support for the AT90USB646 to the Teensy bootloader now that PJRC have released the Teensy++ board.

Ensure unfinished SideShow demo uses an unallocated PID value within the LUFA range.

Added new Endpoint_ClearStatusStage() convenience function to assist with the status stages of control transfers.

Removed vague USB_IsConnected global - test USB_DeviceState or USB_HostState explicitly to gain previous functionality.

Removed USB_IsSuspended global - test USB_DeviceState against DEVICE_STATE_Suspended instead.

Fixed possible enumeration errors from spinloops which may fail to exit if the USB connection is severed before the exit condition becomes true.

Add extra tests to the MassStorage device demo and class driver for validating command blocks from the host.

Add explicit guards to all device mode tasks to ensure the device is connected and configured before running the task, to prevent any user tasks from locking up the main USB task if the device has not been properly configured.

Change Doxygen configuration files to not produce 4096 directories for the documentation files -- the LUFA components do not generate enough documentation files to justify the large performance hit of creating so many directories.

Fix missing Doxygen documentation in the Class Driver Mass Storage Device demo.

Fixed error in GenericHID descriptors preventing it from passing the USB-IF HID tests (thanks to Søren Greiner).

Added new TOTAL_NUM_CONFIGURATIONS option, removed USE_SINGLE_DEVICE_CONFIGURATION compile time option (but silently convert it to USE_SINGLE_DEVICE_CONFIGURATION internally for compatibility).

Added new USE_FLASH_DESCRIPTORS compile time option. By default, descriptors can now lie in mixed memory spaces (specified by a new parameter to the CALLBACK_USB_GetDescriptor() function) unless one of the USE_*_DESCRIPTORS compile time option is specified.

Fix HID class device driver -- if a SetIDle request is issued with the LSB of wValue set to zero, the idle period must be set for all HID interfaces.

Fix Keyboard and Mouse demos, Idle period is now multiplied by 4 as the period is read into and sent out of the device to ensure it is always stored as a multiple of 1ms. Fixes Keyboard demo using an initial Idle period of 2s rather than 500ms (thanks to Brian Dickman).

Move out the internal device serial descriptor reading routine into a seperate static function, rather than being part of USB_Device_GetDescriptor.

Added new EEPROM and FLASH buffer versions of the Endpoint and Pipe stream functions. Changed Endpoint.c and Pipe.c to use a templated system to build the seperate functions, rather than duplicating each function's code many times.

Documented FAST_STREAM_TRANSFERS compile time option.

Reduced the TCP window size for the RNDIS demos (Class and LowLevel) to make them compatible with the AT90USB64x.

Seperated out Lib components of the incomplete BluetoothHost demo application out into a seperate Lib subfolder.

Changed F_CLOCK entries in project makefiles to alias to F_CPU by default, as this is the most common case.

Dataflash_WaitWhileBusy() now always ensures that the dataflash is ready for the next command immediately after returning, no need to call Dataflash_ToggleSelectedChipCS() afterwards.

Added new DATAFLASH_CHIP_MASK() macro to the Dataflash driver, which returns the Dataflash select mask for the given chip index.

Updated MassStorage device block write routines to use ping-pong Dataflash buffering to increase throughput by around 30%.

Added parameter directions to function parameter documentation.

Added new experimental FAST_STREAM_FUNCTIONS compile time option to speed up stream transfers at the expense of a higher FLASH consumption (needs testing to verify improved throughput).

Fixed MassStorage demo not clearing the reset flag when a Mass Storage Reset is issued while not processing a command.

Added new USE_INTERNAL_SERIAL define for using the unique serial numbers in some AVR models as the USB device's serial number, added NO_INTERNAL_SERIAL compile time option to turn off new serial number reading code. Updated Mass Storage and CDC based demos to use the new device serial number if the device it is compiled for supports it.

Added USE_INTERNAL_SERIAL compile time option to automatically read out the internal unique serial number as the device's serial number descriptor on supported AVR models.

Fix makefiles -- the auto-addition of -D switches to each LUFA compile time option was faulty, due to GNUMake becomming confused by the spaces in the USE_STATIC_OPTIONS lines. Make user add in the switches explicitly instead.

Break device mode class driver interfaces into seperate config and state structs which are then combined, for clarity. Move device mode class driver interfaces back into the device mode class driver headers from the common class headers to make room for host class interfaces.
