Reduce prescaler of the flush timer in the USBtoSerial demo, so that buffer overruns will not occur regardless of hardware and baud rate settings.

Alter the ring buffer library headers to have both atomic and non-atomic insertion/removal routines. Modify the existing projects so that buffer operations performed in an ISR use the shorted non-atomic versions, as they are already performed in a blocking ISR.

Alter USBtoSerial demo so that it does not enter a blocking loop to send data from the USB to the USART, as this can cause dropped bytes in the reception code if large amounts of data are sent in both directions at the same time. Added a flush timer to the USBtoSerial code for the USART to USB interface, so that multiple bytes can be sent in the same USB packet.

Added new Drivers/USB/LowLevel/Device.c file to house Device mode specific functions that are more complicated than simple macros. Moved USB_Device_SendRemoteWakeup() to the new Device.c source file and corrected it to unfreeze and restart the USB controller clock before issuing a Remote Wakeup request.

Removed the USB_Device_IsRemoteWakeupSent() and USB_Device_IsUSBSuspended() macros, as they are now obsolete.

Maximise the size of the ring buffers in the Benito/XPLAINBridge/USBtoSerial projects, so that they should never become full under normal conditions.

Oops - light weight ring buffer documentation used \ref instead of \param to document function parameters.

Add the svn:eol-style property onto new files which where missing it to ensure uniform line endings.

Replace ring buffer library in Benito and USBtoSerial projects with the new lightweight ring buffer header to improve reliability.

Renamed CDC device class demos' ManagementEndpoint descriptor to NotificationEndpoint to more accurately indicate its purpose.

Add svn:eol-style property to source files, so that the line endings are correctly converted to the target system's native end of line style.

Change over instances of "make" in the makefiles to "$(MAKE)" to allow for the make tool to be overridden.

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.
