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.

Add descriptor class, subclass and protocol constants to the class drivers, modify all demos to use them where possible.

Move out private/internal host class driver constants to the common class driver headers, so that they can be used in the Low Level host mode demos.

Ensure all demos, projects and bootloaders use the class driver constants where possible to minimise code repetition.

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.

Better algorithm to extract and convert the internal device serial number into a string descriptor (if present).

Fix incorrect warning text when an unsuitable F_CLOCK value is given.

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

Fix SoftUART.c not compiling due to accidental check in of changes not yet complete in the rest of the XPLAINBridge project code.

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 new NO_SOF_EVENTS compile time option, enabled in the bootloaders to reduce the compiled binary size.

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.

Fixed broken FLASH/EEPROM programming in the AVRISP-MKII clone project when writing in non-paged mode and the polling byte cannot be used.

Fixed LowLevel JoystickHostWithParser demo not saving the chosen HID interface's report descriptor size.

Simplified low level Host demo configuration descriptor parser routines.

Make Printer Host mode Class driver interface descriptor search routine pre-cast the current interface descriptor to simplify the value checks.

Make Host mode Class drivers only set the class driver instance's state values once a compatible interface has been found within the device.

Fix typo in MIDI low level device demo.

Fix low level host mode demos not correctly fetching the next endpoint when an invalid interface is discarded.

Update the pipe configuration routines in the host mode class drivers so that they use the same new code to enumerate compatible devices to increase reliability. Add support to the host mode class drivers for non-sequential (but non-overlapping with other interface) pipe numbers.

Reverted Endpoint/Pipe non-sequential configuration hack, placed restriction on the configuration order instead to ensure maximum reliability.

Altered all low level device and host mode demos to ensure that endpoints and pipes are configured in ascending order properly.

Rewrote all low level host mode demos' configuration descriptor parser code to ensure that pipes are enumerated in ascending order, and to ensure maximum compatibility with devices.

Incremented all device mode demo's device descriptor revision numbers to ensure that any descriptor changes are re-fetched on machines which have enumerated previous versions.

Changed default value for the reset polarity parameter in the AVRISP-MKII project so that it defaults to active low drive.

Fixed incorrect USB_DeviceState value when unconfiguring the device without an address set.

Add class name prefixes to missed constants in the class drivers to give all class driver elements a consistent namespace.

Fixed incorrect LEDs_ChangeLEDs() function in the Benito board LED driver.

Added CDC functional descriptor structs to the Low Level CDC demos and CDC class bootloader, to improve the readability of the descriptors.

Fixed BootloaderCDC project failing on some operating systems due to removed Line Encoding options (thanks to Alexey Belyaev).

Add new CDC descriptor structs to the CDC class driver, so that the CDC demos can use human readable field names.

Rename prefix for Still Image Host class driver functions from "SImage_" to "SI_" to remain consistent with the rest of the driver.

Remove dfu-programmer program switches, to ensure maximum compatibility with all dfu-programmer versions.

Added the --suppress-bootloader-mem option to the makefile dfu target, to ensure that writes to the bootloader section of the AVR's flash memory are ignored (thanks to Axel Rohde).

Fixed incorrect command name for EEPROM memory programming in the makefile dfu-ee target.

Makefile whitespace fixes.

Fixed endpoint selection within the CALLBACK_HID_Device_CreateHIDReport() callback function causing broken GET REPORT requests.

Minor whitespace fixes.
