Added new doxygen_upgrade and doxygen_create targets to the DOXYGEN build system module. Clean up CORE build system module.

Fixed missing Win-32bit compatibility sections in the LUFA INF driver files (thanks to Christan Beharrell).

Fixed inverted LED driving code for the Arduino Leonardo board. Fixed inverted LEDs_GetLEDs() function implementation for the Benito, Minimus and Arduino UNO boards.

Added support for the Arduino Leonardo board. Swap Olimex 32U4 RX/TX LED masks so that it lines up with the Arduino boards.

Added workaround for broken VBUS detection on AVR8 devices when a bootloader starts the application via a software jump without first turning off the OTG pad (thanks to Simon Inns)

Fixed endianess issues in the RNDIS host class driver for UC3 devices (thanks to Andrew Chu). Fix broken build for UC3 devices when ORDERED_EP_CONFIG compile time option is set.

Fixed incorrect Micropendous board LED driver LEDs_SetAllLEDs() and LEDs_ChangeLEDs() function implementations (thanks to MitchJS).

Fixed CDC and DFU bootloaders API page erase and write function failures (thanks to Martin Lambert).

Fixed invalid configuration descriptor in the low level KeyboardMouse device demo (thanks to Jun Wako).

Added new JTAG_ENABLE() macro for the AVR8 architecture. Fixed the JTAG_DISABLE() macro clearing all other bits in MCUSR when called.

Moved the XPLAIN board specific bootloader entry condition code to the Application_Jump_Check() function of the DFU bootloader, added support for the original XPLAIN board to the CDC class bootloader.

Fixed swapped Little Endian/Big Endian endpoint and pipe write code for the UC3 devices (thanks to Andrew Chu).

Added new RESET_TOGGLES_LIBUSB_COMPAT compile time option to the AVRISP-MKII clone programmer project (thanks to Robert Spitzenpfeil).

Fixed compile error with the unreleased ATMEGA32U6 device.

Add branch for the conversion of demos to use standard C header files for configuration, rather than makefile defined macros.

Changed board LED driver implementations of LEDs_ToggleLEDs() for the AVR8 architecture to use the fast PIN register toggle alternative function for speed.

Fixed broken MIDI host driver MIDI_Host_ReceiveEventPacket() function due to not unfreezing the MIDI data IN pipe before use (thanks to Michael Brown).

Increased endpoint polling interval for all demos and projects to 5ms, as 1ms was causing some enumeration issues on some machines (thanks to Riku Salminen).

Fixed possible deadlock in the CDC device driver if the USB connection is dropped while the CDC_REQ_SetLineEncoding control request is being processed by the stack (thanks to Jonathan Hudgins).

Fixed incorrect DFU version number reported to the host in the  DFU bootloader descriptors. Fixed incorrect version hundredths value encoding in VERSION_BCD() macro (thanks to Georg Glock).

The library bootloaders will now correctly start the user application after a watchdog-based application start, even if the /HWB line is held low externally during the reset phase.

Changed MIDI event structure MIDI_EventPacket_t to use a single field for the combined virtual cable index and command ID, to prevent bitfield packing issues on some architectures (thanks to Darren Gibbs).

Fixed AVRISP-MKII programmer project reset line polarity inverted when the generated EEP file is loaded into the USB AVR's EEPROM and avr-dude is used.

Fixed incorrect reponse to GET STATUS requests in device mode if NO_DEVICE_SELF_POWER or NO_DEVICE_REMOTE_WAKEUP tokens are defined (thanks to Georg Glock).

Fixed CDC and DFU bootloaders failing to compile when the bootloader section size is 8KB or more (thanks to Georg Glock).

Removed the old pseudo-scheduler from the library as it was unused and deprecated since the 090810 release.

Reverted AVRISP-MKII clone project watchdog based command timeout patch in favour of a hardware timer, to allow for use in devices with WDTRST fuse programmed.

Removed variable axis support from the HID_DESCRIPTOR_JOYSTICK() macro due to OS incompatibilities, replaced with fixed 3-axis joystick report structure.
