Removed the ENDPOINT_DESCRIPTOR_DIR_* macros in favour of the shorter ENDPOINT_DIR_* macros, which can now be used with both Endpoint_ConfigureEndpoint() and in the device descriptors.

Fixed error in the pipe unordered allocation algorithm for the AVR8 devices breaking compatibility with some devices.

Add endianness information to the class driver and core structure definitions.

Move out the unused Ethernet_Frame_Info_t structure definition to the RNDIS device demos where it is needed.

Seperate out the device demos and project's configuration descriptor structure definitions to clearly indicate what descriptors belong to which interface.

Add new "checksource" target to the library makefiles, for automated source file existance checking.

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

Add RNDIS Device support to the Webserver project, so that the files stored on the device can be viewed from a web-browser while the board is plugged into a host machine.

Add new RNDIS_Host_IsPacketReceived(), RNDIS_Device_ReadPacket() and RNDIS_Device_WritePacket() functions to the Device RNDIS Class Driver.

Modify RNDIS demos to suit the simplified Ethernet_Frame_Info_t structure.

Remove redundant type information for bitfield elements, other than the signed/unsignedness of the element.

Change type of USB_SelectedPipe and USB_SelectedEndpoint for the AVR32 UC3 architecture to uint32_t to reduce the compiled code size.

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.

Add static keyword to all project globals whose scope should be restricted to the same module as they are declared in.

Tighten up the HID class bootloader code slightly, document that it currently exceeds 2KB of bootloader space for all models other than the Series 2 USB AVRs.

Add const to all project descriptor definitions for safety.

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.

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

Lower bulk endpoint polling rate in the descriptors to the lowest possible value to give maximum throughput.

Fixed incorrect PollingIntervalMS values in the demo/project/bootloader endpoint descriptors (thanks to MCS Electronics).

Renamed the EVENT_USB_Device_UnhandledControlRequest() event to EVENT_USB_Device_ControlRequest() as it is now fired before the library request handlers, not afterwards.

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.

Add descriptor class, subclass and protocol constants to the class drivers, modify all demos to use them where possible.

Move out private/internal host class driver constants to the common class driver headers, so that they can be used in the Low Level host mode demos.

Ensure all demos, projects and bootloaders use the class driver constants where possible to minimise code repetition.

All USB class drivers are now automatically included when LUFA/Drivers/USB.h is included, and no longer need to be seperately included.

All LowLevel demos changed to use the constants and types defined in the USB class drivers.

Reverted Endpoint/Pipe non-sequential configuration hack, placed restriction on the configuration order instead to ensure maximum reliability.

Altered all low level device and host mode demos to ensure that endpoints and pipes are configured in ascending order properly.

Rewrote all low level host mode demos' configuration descriptor parser code to ensure that pipes are enumerated in ascending order, and to ensure maximum compatibility with devices.

Incremented all device mode demo's device descriptor revision numbers to ensure that any descriptor changes are re-fetched on machines which have enumerated previous versions.

Add new CDC descriptor structs to the CDC class driver, so that the CDC demos can use human readable field names.

Rename prefix for Still Image Host class driver functions from "SImage_" to "SI_" to remain consistent with the rest of the driver.

Remove dfu-programmer program switches, to ensure maximum compatibility with all dfu-programmer versions.

Added the --suppress-bootloader-mem option to the makefile dfu target, to ensure that writes to the bootloader section of the AVR's flash memory are ignored (thanks to Axel Rohde).

Fixed incorrect command name for EEPROM memory programming in the makefile dfu-ee target.

Makefile whitespace fixes.

Make project makefiles correctly clean intermeditary build files from assembly and C++ sources (thanks to Daniel Czigany).

Clarify in the project documentation files what the each of the different USB AVR device "series" comprises of.

Changed the signature of the CALLBACK_USB_GetDescriptor() callback function so that the descriptor pointer is const, to remove the need for extra casting inside the callback (thanks to Jonathan Kollasch).

Removed complicated logic for the Endpoint_ConfigureEndpoint() function to use inlined or function called versions depending of if the given bank size is a compile time constant, as the compiler does a better job of optimizing with basic code.

Changed over all device demos to use a clearer algorithm for the configuring of the application's endpoints.

Fix invocations of avr-size in all makefiles broken on unpatched *nix systems, due to the recent update to the latest WinAVR makefile template.

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

Update all demos, projects and bootloaders to indent all function parameters, one per line, for better readability.

Add missing const qualifiers to the demos.

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.
