Add double banking property to LUFA powered projects in the Projects directory. Add guards to macro parameters to ensure that formulas passed as parameters don't mess up the internal macro structure.

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.

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.

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.

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.

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.

Added new HID_HOST_BOOT_PROTOCOL_ONLY compile time token to reduce the size of the HID Host Class driver when Report protocol is not needed.

Fixed issue in the HID Host class driver's HID_Host_SendReportByID() routine using the incorrect mode (control/pipe) to send report to the attached device.

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.

Fixed PrinterHost demo returning invalid Device ID data when the attached device does not have a device ID (thanks to Andrei Krainev).

Doxygen fixes to \param directives to give data direction in all projects. Make HID item filtering routines clearer in the HID WithParser demos.

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.

Add new attributes to the HID Report Parser and HID Host Mode Class driver to keep track of the largest report the device can send for buffer allocation purposes. Change MouseHostWithParser and KeyboardHostWithParser demos to only allocate the needed number of bytes.

Add new MouseHostWithParser and KeyboardHostWithParser Host Class driver demos.

Fix KeyboardHost ClassDriver demo; boot protocol keyboard report structure in the Host Mode HID Class driver uses the full keycode array from the attached device.

Finish Class Driver MouseHost demo. Update HID Host Class driver; boot protocol now works, still need to finish and test report protocol mode.

Added new USB_GetHIDReportSize() function to the HID report parser to retrieve the size of a given report by its ID.

More additions to the unfinished HID Host Class Driver.

Added support for the officially recommended layout of the external peripherals connected to the BUMBLEB board.

Added flag to the HID Host Class driver to indicate the currently selected reporting protocol.

Fix Mass Storage Host Class driver GetMaxLUN command - incorrect function return codes used in comparison to check for success.

Add HID Host Class driver functions to set the report protocol, add more class driver documentation.

Fixed MIDI Device Class driver not sending/receiving MIDI packets of the correct size (thanks to Thomas Bleeker).

Prevent the CDC Device Class driver from sending empty IN packets on every service task call - only send termination packets when data is in the endpoint.

Remove USE_NONSTANDARD_DESCRIPTOR_NAMES compile time token, split out standard descriptors into seperate USB_Descriptor_* and USB_StdDescriptor_* structures so that both can be used within the one project.

Add guard to the HID Host Class driver SetProtocol command, to ensure that the device supports boot protocol mode before issuing the request.

Change HID report parser so that it can calculate and record the sizes (IN, OUT and FEATURE) of each report within the device, by report ID. This will be required in host mode, so that the host can determine how many bytes of data must be read in for each report.

Add to MouseHostWithParser and KeyboardHostWithParser demos to print out the report sizes when a valid device is connected.

Corrected incorrect signature bytes for the AT90USB82 and added support for the ATMEGAXX2 variant AVRs to the DFU bootloader.

Added warning to the EVENT_USB_Device_Connect() and EVENT_USB_Device_Disconnect() events that they may be fired multiple times during device enumeration on the series 2 AVRs.
