Add new "checksource" target to the library makefiles, for automated source file existance checking.

Massive corrections to the project documentation and code comments, thanks to Russian translation services provided by Andrey from Microsin.ru.

Add __VA_ARGS__ support to the LUFA supplied ISR macro. Add proper result typecasting to the SWAPENDIAN_* macros.

Switch to using -1 on the UC3 target to obtain a register mask with all bits set (for clearing interrupts and status flags).

Fix incorrect USB controller mode on the UC3 when a fixed mode is specified as a compile time option due to AVR32_USBB.USBCON.uide being set by default.

Make USB_Descriptor_String_t use a uint16_t for Unicode strings on all targets except the AVR8 (retained for backwards compatibility).

Slight cleanups to the architecture specific makefile templates to make the common configuration sections as identical as possible.

Update architecture specific makefile templates so that they are as close to one-another as possible.

More updates to remove architecture-specific comments from the documentation, alter USBMode.h preprocessor logic to support future architectures more easily.

Start update of documentation to support possible multiple architectures in the future - alter \file documentation to automatically copy in the module documentation where possible.

Add new ARCH option to the makefiles to (eventually) specify the target device architecture. Update non-usb peripheral drivers to reflect future multiple architecture support.

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.

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.

Make project makefiles correctly clean intermeditary build files from assembly and C++ sources (thanks to Daniel Czigany).

Added new project makefile template to the library and moved board driver stub files into in a new CodeTemplates directory.
