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

Fixed all Class drivers to ensure they have appropriate guards on each function to ensure the device is enumerated before running, fixed error codes on all guards to return "DeviceDisconnected" where possble.

Renamed HOST_SENDCONTROL_DeviceDisconnect enum value to HOST_SENDCONTROL_DeviceDisconnected to be in line with the rest of the library enum error codes.

Added new RNDISHost Host LowLevel demo. Fixed misnamed Pipe_SetPipeToken() macro for setting a pipe's direction. Fixed CDCHost failing on devices with bidirectional endpoints.

Add some missing documentation to some of the library demos.

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

Add information on the new MouseHostDevice dual role demo to the library documentation. Add a 0x prefix to the LUFA_VERSION_INTEGER define to ensure that it is stored as BCD, and not an octal value.

Add new MouseHostWithParser and KeyboardHostWithParser Host Class driver demos.

Added support for the officially recommended layout of the external peripherals connected to the BUMBLEB board.

Added flag to the HID Host Class driver to indicate the currently selected reporting protocol.

Add link to third-party signed version of the official FLIP DFU driver for 64-bit Windows OSes to the DFU bootloader readme file.

Add HTML anchor links to URLs in the documentation to ensure that they are rendered correctly in the generated documentation.

Added new Benito project, a simple modified USB-to-Serial bridge for the programming of AVRs using the official Arduino bootloader.

Added parameter directions to function parameter documentation.

Added new experimental FAST_STREAM_FUNCTIONS compile time option to speed up stream transfers at the expense of a higher FLASH consumption (needs testing to verify improved throughput).
