Massive corrections to the project documentation and code comments, thanks to Russian translation services provided by Andrey from Microsin.ru.

Added TWI baud rate prescaler and bit length parameters to the TWI_Init() function (thanks to Thomas Herlinghaus).

Make sure the peripheral driver .c files include the driver dispatch header, rather than the architecture specific header files.

Rename architecture specific driver files, to make them appear with uniquely identifying filenames in the documentation.

Add new ARCH option to the makefiles to (eventually) specify the target device architecture. Update non-usb peripheral drivers to reflect future multiple architecture support.

Renamed the PRNT_Host_SendString(), CDC_Host_SendString() and CDC_Device_SendString() functions to *_SendData(), and added new versions of the *_SendString() routines that expect a null terminated string instead.

Added new Serial_SendData() function to the Serial driver.

Removed SerialStream module, rolled functionality into the base USART Serial peripheral driver instead through the new Serial_CreateStream() and Serial_CreateBlockingStream() methods.

Renamed the Serial byte send/receive functions to remain consistent with the CDC driver's byte functions.

Altered the serial byte receive function to make it non-blocking.

Added new high level TWI packet read/write commands, altered behaviour of the TWI_StartTransmission() function.

Spell check source code files.

Documentation improvements - put driver example code into its own section, fix incorrect and missing section names.

Made the USARTStream global public and documented in the SerialStream module, allowing for the serial USART stream to be accessed via its handle rather than via the implicit stdout and stdin streams.

Add logical grouping of related #define values for better Doxygen documentation.

Changed over www.fourwalledcubicle.com links to the new www.lufa-lib.org redirect domain, including the new aliased links for LUFA-related pages such as the various download/source control mirrors and support lists.

Fix SoftUART.c not compiling due to accidental check in of changes not yet complete in the rest of the XPLAINBridge project code.

Fix incorrect ADC driver documentation for the parameters of ADC_Init(), fix incorrect call to ADC_Init() in the TemperatureDatalogger project.

Fixed Serial peripheral driver not turning off the USART before reconfiguring it, which would cause incorrect operation to occur (thanks to Bob Paddock).

Oops - fix mixed "initialize" and "initialise" - opt for American spelling due to its wide use in technical standards.

More spell checking of all source files -- correct missed errors, switch to EN-GB spelling dictionary.

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.

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.

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.

Minor tweaks to the library documentation.

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