Fixed Benito and USBtoSerial projects not turning off the USART before reconfiguring it, which could cause incorrect operation to occur (thanks to Bob Paddock).

Add special support to the AVRISP-MKII for the new model USBTINY-MKII's additional LED to indicate target power source.

Add support to the USBTINY-MKII's additional LED in the board's LED driver header.

Changed LED indicator masks for the AVRISP-MKII project, so that there are defined roles for each LED.

Added support to the AVRISP-MKII project for ISP speeds slower than 125KHz via a new software SPI driver.

Added new SPI_ORDER_* data order masks to the SPI peripheral driver.

Use static inline intermediatary functions in Endpoint.h to handle the masking for the private endpoint configuration routine, instead of performing the masking in the Endpoint_ConfigureEndpoint() macro.

Move over message ID specific header data to unions inside the standard TMC header structure, so that all header data is read in one chunk in the incomplete TMC demo.

Rename reserved members of all structs so that they are uniformly named across all demos/projects/bootloaders.

Added start of the Incomplete TMC demo's command parser code.

Added periodic flush timer to the Benito project. Alter the serial transmission code so that sent bytes do not block the remainder of the main program code from running.

Convert over internal pseudo-function macros to true inline functions for added type-safety and compile-checking.

Indent core library function parameters so that there is only one parameter per line, to increase readability.

Move and rename DevChaper9.c/.h and HostChapter9.c/.h to the HighLevel directory, new named DeviceStandardReq.c/.h and HostStandardReq.c/.h.

Rename LowLevel.c/.h to USBController.c/.h.

Remove dependancies on the complete <avr/io.h> header in the HighLevel USB driver directory, to ensure less work is required in later (possible) ports.

Reduce spacing of the structure elements in StdDescriptors.h to make the code more readable.

Fixed MIDI_Device_SendEventPacket() not correctly waiting for the endpoint to become ready (thanks to Robin Green).

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.

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).

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.

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.

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

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.

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.

Add TEST RFCOMM command handler. Remove the RFCOMM channel UseUIFrame element, as the Bluetooth adaptions to RFCOMM only allow UIH frames to be used.

Added new SWAPENDIAN_16() and SWAPENDIAN_32() macros to Common.h for statically initialized variables at compile time.

Minor tweaks to the library documentation.
