Add new module source variables to the library core makefile, so that module sources can be added to a project's makefile on a per-module rather than per-file basis.

Disable strict aliasing explicitly in the project makefiles, as this is apparently enabled by default in newer AVR-GCC builds, and aliasing is used heavily for type-punning through the LUFA and third party library's codebase.

Removed the automated checking of event names in the demo, project and bootloader makefiles due to inconsistancies between the behaviour of the command line tools used to perform the check on each platform.

Removed the internal endpoint and pipe memory allocation macros, as this is already performed directly in the code. Simplify the endpoint and pipe reset procedure.

Change AVRISP-MKII and XPLAINBridge descriptors to indicate that the device is bus-powered only. Add compile time options to reduce the compiled size of the firmware.

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.

Add glitch protection to the software UART in the XPLAINBridge project code, so that very short glitches on the RX line don't cause a frame reception to occur.

Major changes to the XPLAINBridge software UART code for performance and reliability. New code reduces the number of missed characters and misread characters.

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.

Make XPLAINBridge serial bridge much more reliable for the reception of characters from the XMEGA through the software UART interface.

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

Moved calls to V2Params_UpdateParamValues() out of the main AVRISP-MKII and XPLAINBridge project loops and into the AVRISP management function.

Spell check code and manual pages. Remove custom Doxygen CSS stylesheet, as the new 1.7 Doxygen's default stylesheet is much better.

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

Added new VTARGET_REF_VOLTS and VTARGET_SCALE_FACTOR compile time defines to the AVRISP-MKII programmer project to set the VTARGET reference voltage and scale factor.

Fixed XPLAINBridge project not correctly reading the XMEGA's supply voltage when reporting back to the host.

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

Switch software UART over to timer 1 and remove timer prescaling to try to prevent integer rounding errors and thus minimize the possible error of the UART code.

Rename software USART driver globals to make the code more in line with the rest of the XPLAINBridge project.

Make software USART used in the XPLAINBridge project directly check and store into the ring buffers, rather than polling from the main program loop to avoid added latency.

Create a new LightweightRingBuffer.h header file for the XPLAIN project to abstract out the new ring buffer without a performance penalty.

The RingBuff library code has been replaced in the XPLAINBridge project with an ultra lightweight buffer to help  improve the reliability of the bridge.

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

The LIBUSB_FILTERDRV_COMPAT compile time option in the XPLAINBridge and AVRISP-MKII projects has been renamed LIBUSB_DRIVER_COMPAT, as it applies to all software on all platforms using the libUSB driver.

Fix Benito makefile which was accidentally changed during testing.

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.

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.
