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.

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

Minor documentation improvements.

Organise the current version changelog better to group core and non-core changes together.

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).

Fixed PDI/TPI programming speed of ~250KHz in the AVRISP-MKII Clone project, instead of the desired 500KHz.

Fixed incorrect PollingIntervalMS values in the demo/project/bootloader endpoint descriptors (thanks to MCS Electronics).

Fixed calculation of timer register reload values derived from F_CPU; must subtract one from the division result for the compare value to be correct.

Change AVRISP-MKII rescue clock speed to 4MHz to ensure that a 125KHz ISP speed works regardless of the target's fuses (i.e. DIV8 set).

Renamed the EVENT_USB_Device_UnhandledControlRequest() event to EVENT_USB_Device_ControlRequest() as it is now fired before the library request handlers, not afterwards.

Fixed USBtoSerial and XPLAINBridge demos discarding data from the PC if the send buffer becomes full.

Fixed MIDI class driver send routines silently discarding packets if the endpoint or pipe is busy (thanks to Robin Green).

Rescue clock of the AVRISP-MKII moved to the AVR's OCR1A pin, so that the clock can be generated at all times when 125KHz ISP programming mode is selected.

Rename new CDC class bootloader NO_LOCK_BYTE_SUPPORT compile time option to NO_LOCK_BYTE_WRITE_SUPPORT as reads are still permitted.

Clean up CDC bootloader command processing code.

Added new NO_BLOCK_SUPPORT, NO_EEPROM_BYTE_SUPPORT, NO_FLASH_BYTE_SUPPORT and NO_LOCK_BYTE_SUPPORT compile time options to the CDC class bootloader.

Added new NO_CLASS_DRIVER_AUTOFLUSH compile time option to disable automatic flushing of interfaces when the USB management tasks for each driver is called.

The MIDI class drivers now automatically flushes the MIDI interface when the MIDI class driver's USBTask() function is called.

Changed AudioInput and AudioOutput demos to reload the next sample via an interrupt rather than polling the sample timer.

All USB class drivers are now automatically included when LUFA/Drivers/USB.h is included, and no longer need to be seperately included.

All LowLevel demos changed to use the constants and types defined in the USB class drivers.

Renamed ENDPOINT_DOUBLEBANK_SUPPORTED() to ENDPOINT_BANKS_SUPPORTED() and changed it to return the maximum number of supported banks for the given endpoint.

Fixed MIDI_Host_Flush() not aborting early when the specified MIDI host interface was not configured.

Small documentation improvements to explicitly reference tokens in Doxygen, to ensure that they are converted to cross-reference links in the output files.

Moved the USB device selection logic for ENDPOINT_TOTAL_ENDPOINTS further up in Endpoint.h to where the endpoint bank capabilities are determined, to reduce the total number of device-specific logic.

Change USB_Host_WaitMS() to test and disable the HSOFI interrupt before resuming the bus, so that it does not fire before the delay loop has run.

Add missing const qualifier to the parameter of USB_Host_ClearPipeStall().

Fixed random enumeration failure while in device mode due to interrupts causing the Set Address request to exceed maximum timings.

Added SVN eol-style property to the library driver files that are missing it.

Cache the USB_DeviceState variable internally in the library core when multiple checks are required in a single loop iteration, to reduce compiled code size.

Revert change to the AVRISP-MKII project for fuse byte programming via the CMDEX bit - this appears to be an error in the XMEGA manual external memory programming table.
