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.

Fixed HID device class driver still using PrevReportINBuffer for GetReport control requests even when it has been set to NULL by the user application (thanks to Axel Rohde).

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.

Remove the timeout period extension code from the AVRISP project, as no single command should ever exceed the maximum timeout period. Extend timeout period to 1 second per command, so that an accidental timeout will never occur.

Rename the AVRISP main source files to AVRISP-MKII so that it matches the project name. Add AVRStudio project file for the AVRISP-MKII project.

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.

Oops - ACL layer Bluetooth_SendPacket() function should check and allow NULL channels, since that indicates a control channel request.

Fix up Doxgen documentation for the Bluetooth stack code.

Rename Bluetooth stack function parameters to clearly indicate what sort of Bluetooth channel (ACL, RFCOMM) is required for each parameter, to make the code easier to read.

Add a new RFCOMM_ChannelSignalsReceived() Bluetooth stack callback from the RFCOMM layer for when the remote device sends new terminal control signals.

Fix RFCOMM_SendData() not aborting correctly when the requested RFCOMM channel is not found.

Rewrote the implementation of the SwapEndian_16() and SwapEndian_32() functions so that they compile down in most instances to minimal loads and stores rather than complicated shifts.

Fixed SCSI.c implementations of all the demos/projects casting the block count to a 32-bit temporary before calling SwapEndian_16().

Add a new RFCOMM_ChannelOpened() callback event for when logical RFCOMM channels are opened in the BluetoothHost demo. Make the demo echo back sent characters to the remote device.

Move out Bluetooth stack callback functions to a seperate BluetoothEvents.c/.h set of files for clarity in the Incomplete BluetoothHost demo. Add a new stack callback for opened ACL channels, make the demo save the RFCOMM channel when opened so that it does not have to search for it on each iteration of the main program loop.

Improve commenting of the Dataflash stub board driver file, to prevent confusion of what the dataflash selection masks need to be. Update stub driver to automatically interleave data between the chips if two Dataflash chips are present.

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.

Move out RFCOMM channel structure init code to a seperate routine, to save on compiled code space and to prevent copy-paste errors.

Add RFCOMM service routine, to send pending configuration requests on RFCOMM channels. Add in RFCOMM channel config flags, to determine which configuration commands have been sent and received.

Add a new RFCOMM_SendChannelSignals() function to transmit a change in V24 terminal handshake lines to the receiving device.

Prevent SABM packets sent to the control DLCI in the RFCOMM layer from creating a new channel entry, as the control DLCI does not have connection data associated with it.

Fix up MSC control packet handling so that received responses can be acknowledged correctly, so that the RFCOMM layer can record when the receiving device has ACKed a sent change in V24 terminal handshake lines.

Make Bluetooth ACL channel searches skip over closed (invalid) channels. RFCOMM channels are considered invalid when the channel state is closed, not when the DLCI is zero - fix incorrect code.
