Remove incorrect Abstract Call Management class specific descriptor from the CDC demos, bootloaders and projects.

Change AVRISP project's timeout to be interrupt based again, but make the interrupt itself interruptable and use a seperate assembly file to hand-optimize the ISR code.

Removed the cast to uint16_t on the set baud rate in the USBtoSerial project, so that the higher >1M baud rates can be selected (thanks to Steffan).

Relocate USBInterrupt.c/.h from the HighLevel USB driver directory to the LowLevel directory as it is hardware-dependent.

USB_Init() no longer calls sei() to enable global interrupts - this must now be done in the user application once all init code has run.

Standardized the naming scheme given to configuration descriptor sub-elements in the Device mode demos, bootloaders and projects.

Fix errors in the MouseHostWithParser demo from incorrect use of the HID_ALIGN_DATA() macro.

Increased throughput of the USBtoSerial demo on systems that send multiple bytes per packet (thanks to Opendous Inc.).

New BOARD value option BOARD_NONE (equivelent to not specifying BOARD) which will remove all board hardware drivers which do not adversely affect the code operation (currently only the LEDs driver).

Spell-check code/comments in the Webserver/AVRISP-MKII projects.

Update driver INF files - change manufacturer name from the original template's name to the Four Walled Cubicle website.

Fix Doxygen configuration files' input file exclusion filters.

Add new HotmailNotifier project, which changes a LED's colour based on the user's unread email count as sent from Windows Live Messenger.

Fix project text files to refer to "project" instead of "demo".

Add double banking property to LUFA powered projects in the Projects directory. Add guards to macro parameters to ensure that formulas passed as parameters don't mess up the internal macro structure.

Moved USBtoSerial demo the Projects directory, as it is simply an expanded CDC demo. Added const qualifier to Endpoint/Pipe stream write routines.
