Rename TOTAL_NUM_CONFIGURATIONS to FIXED_NUM_CONFIGURATIONS, to match the existing FIXED_CONTROL_ENDPOINT_SIZE compile time option. Add FIXED_NUM_CONFIGURATIONS to the descriptors of each project using the option.

Make both LowLevel and ClassDriver AudioOutput demos always output to board LEDs, regardless of output mode (removed AUDIO_OUT_LEDS compile time option from the demo). This allows for positive feedback to the user of audio activity regardless of output mode.

Removed interrupt disable/enable from the Device mode control request processing routines, as they can cause problems with user code and can cause infinite spinlocks under some circumstances.

Added new LUFA logo from EDIGMA.COM.

Fixed the ClassDriver GenericHID demo so that it echoes back reports as indicated in the demo overview.

Fix demos based on the device mode HID class driver, as well as the driver itself. Changed HID device class driver to require the user to give a buffer and size to hold the previously generated report, for comparison purposes, and altered the prototype of the CALLBACK_HID_Device_CreateHIDReport() function so that reports can be sent to the host even if there are no apparent changes (useful for relative movements in mice, etc.).

Renamed USB_Device_SetHighSpeed() to USB_Device_SetFullSpeed() so that the correct terminology is used (thanks to Brian Dickman).

Fix USB_PLL_Off() call in the series 4, 6 and 7 microcontroller disconnect interrupt handler code, which wasn't guarded by a test of USB_Options to check if the user has specified manual PLL control (thanks to Brian Dickman).

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.

Ensure that the previous HID reports in the HID device class driver are kept per-instance, rather than per-device.

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.

Extend the automatic serial number descriptor code to read out and send all 10 bytes (20 characters) of the internal serial number on supported AVRs, rather than just the first 6 bytes (12 characters).

Fixed report data alignment issues in the MouseHostWithParser demo when X and Y movement data size is not a multiple of 8 bits.

Fixed HID Report Descriptor Parser not correctly resetting internal states when a REPORT ID element is encountered.

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.

Better solution - change compile time token names to DEVICE_STATE_AS_GPIOR and HOST_STATE_AS_GPIOR and allow the user to set them to the index of the GPIOR register within the device to use.

Added HOST_STATE_AS_GPIOR1 and DEVICE_STATE_AS_GPIOR0 compile time options, the latter of which is used in the bootloaders, to reduce code size.

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.

Collapse configuration descriptor size retrieval and size testing into a single if statement within the new host mode class driver demos for clarity.

Change Host mode class driver Pipe configuration routines -- better to let the application fetch the configuration descriptors once, and then pass them to each class driver in turn.

Add new MouseHost Class Driver demo, unfinished, to allow for better testing of the new prototype Host Mode Class Driver framework. Flesh out start of a HID class Host mode class driver.

Completed host CDC class driver enumeration code.

Ensure new Benito Programmer project matches Don's established LED behaviour - flash LED while generating target /RESET pulse, ping-pong LEDs during enumeration.

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.

Changed USB_Init() and USB_Shutdown() so that they are no longer dependant on oneanother for possible code savings when the interface is never explicitly shut down.

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.
