Add new HID_DESCRIPTOR_VENDOR() macro, change over all projects and Device ClassDriver demos to use it.

Fix reversed byte ordering of multi-byte HID data.

Added support to the HID parser for extended USAGE items that contain the usage page as well as the usage index.

Removed the HID_IOF_NON_VOLATILE and HID_IOF_VOLATILE flags from HID INPUT items where the flag is invalid. Changed over HID OUTPUT items to use HID_IOF_NON_VOLATILE.

Change over MagStripe project to use HID_DESCRIPTOR_KEYBOARD() for its HID report. Change over MouseHostDevice demo to use HID_DESCRIPTOR_MOUSE() for its HID report.

Changed AVRISP-MKII project to use the Watchdog interrupt for command timeouts, to reduce CPU usage and free timer 0 for other uses in the future.

Abuse the the C preprocessor so that the HID macros can automatically encode data into the array from the HID macros automagically, by specifying the bit-width of the data, and the data itself as a single integer value of that width.

New HID report item macros (with HID_RI_ prefix) to allow for easy creation and editing of HID report descriptors.

Changed over all project and demo HID report descriptors to use the new HID report item macros.

Moved the HIDParser.c source file to the LUFA/Drivers/USB/Class/Common/ directory from the LUFA/Drivers/USB/Class/Host/.

Added new high level TWI packet read/write commands, altered behaviour of the TWI_StartTransmission() function.

Spell check source code files.

Oops - The DS1307 contains an unused "DayOfWeek" register that must be accounted for in the new unified DS1307 Time/Day read and write routines.

Changed TempDataLogger project's DS1307 driver to simplify the function interface and prevent a possible race condition.

Altered all endpoint/pipe stream transfers so that the new BytesProcessed parameter now points to a location where the number of bytes in the transfer that have been completed can be stored (or NULL if entire transaction should be performed in one chunk).

Added new Endpoint_Null_Stream() and Pipe_Null_stream() functions.

Removed the NO_STREAM_CALLBACKS compile time option due to the new partial stream transfer feature replacing it.

Fixed errors in the incomplete Test and Measurement device demo preventing proper operation (thanks to Pavel Plotnikov).

The FAST_STREAM_TRANSFERS compile time option has been removed due to lack of use and low cost/benefit ratio.

Add GCC_FORCE_POINTER_ACCESS() macro use to the RingBuffer library header, to attempt to force GCC into producing more efficient code for manipulating the buffers.

Rename RingBuffer header functions and typedefs from RingBuff_* to RingBuffer_* so that it matches the header name.

Documentation improvements - put driver example code into its own section, fix incorrect and missing section names.

Made the USARTStream global public and documented in the SerialStream module, allowing for the serial USART stream to be accessed via its handle rather than via the implicit stdout and stdin streams.

Make a new general RingBuffer.h misc library driver, instead of the per-application LightweightRingBuff.h ring buffers. Change over projects to use the new driver.

Add ORDERED_EP_CONFIG to the device Projects (only) that use only a single class driver, or where the endpoint ordering is fixed, to save on compiled binary size.

Added new GCC_FORCE_POINTER_ACCESS() macro to correct GCC's mishandling of struct pointers.

Combined page and word ISP programming mode code in the AVRISP-MKII clone project to reduce compiled size and  increase maintainability of the code.

Fixed possible programming problem in the AVRISP-MKII clone project when programming specific patterns into a target memory space that is only byte (not page) addressable.

Add DEVICE_STATE_AS_GPIOR=0 compile time option to the library projects, to reduce compiled binary size.

Fixed incorrect definition of the HID_KEYBOARD_SC_D constant in the HID class driver (thanks to Opendous Inc.).

Add extra comments to the ISPTarget.c source file in the AVRISP-MKII clone project.

Fixed possible lost data in the XPLAINBridge, USBtoSerial and Benito projects when the host exceeds the packet timeout period on received packets as set by USB_STREAM_TIMEOUT_MS (thanks to Justin Rajewski).

Changed the XPLAINBridge software UART to use the regular CTC mode instead of the alternative CTC mode via the Input Capture register, to reduce user confusion.

Make the incomplete MIDIToneGenerator project work with up to three notes, using a LRU (Least Recently Used) algorithm to discard the oldest set note when the note table becomes full.

Readd incomplete MIDIToneGenerator project, which can now correctly generate up to three simultaneous notes from MIDI channel 0.

Fixed Benito project discarding incoming data from the USB virtual serial port when the USART is busy.

Minor documentation improvements.

Lower bulk endpoint polling rate in the descriptors to the lowest possible value to give maximum throughput.

Oops - reduce size of each ring buffer in the USBtoSerial and Benito projects so that the RAM is not overflowed on the smaller USB AVR targets (thanks to Andrei from Microsin.ru).

Rename incorrectly named XPROGTarget_SendBreak() function to XPROGTarget_SendIdle(), as it is sending idle bits and not break bits.

Fixed AVRISP-MKII clone project not starting the target's program automatically after exiting TPI programming mode.

Slow AVRISP-MKII clone PDI/TPI programming speed back to 250KHz due to issues with the XPLAINBridge when PDI programming at faster rates.

Speed up XMEGANVM_WaitWhileNVMControllerBusy() by preloading the status register address into the pointer register of the target's NVM controller and then reading via a faster indirect load command.

Added new XCK_RESCUE_CLOCK_ENABLE compile time option to the AVRISP-MKII clone programmer project (thanks to Tom Light).
