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.

Remove internal USB_Device_NibbleToASCII() function in favour of manually inlined code to prevent compilation errors in -O0 optimisation level.

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).

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

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).

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.

Loop in the ClassDriver MIDI device/host demos until there are no more incomming events to process. Only clear the endpoint/pipe bank in the LowLevel MIDI device/host demos when the endpoint is empty after an event read.

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).

Fix XPLAINBridge code broken during the changes to the Rescue Clock generation in the AVRISP-MKII clone project.

Change over all low level host mode project's descriptor comparator routines to perform the descriptor casting in a temp variable to make the code clearer and easier to modify (despite being more verbose).

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.

Add logical grouping of related #define values for better Doxygen documentation.

Changed over www.fourwalledcubicle.com links to the new www.lufa-lib.org redirect domain, including the new aliased links for LUFA-related pages such as the various download/source control mirrors and support lists.
