Altered all endpoint/pipe stream transfers so that the new BytesProcessed parameter now points to a location where the number of bytes in the transfer that have been completed can be stored (or NULL if entire transaction should be performed in one chunk).

Added new Endpoint_Null_Stream() and Pipe_Null_stream() functions.

Removed the NO_STREAM_CALLBACKS compile time option due to the new partial stream transfer feature replacing it.

Fixed errors in the incomplete Test and Measurement device demo preventing proper operation (thanks to Pavel Plotnikov).

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

Add ORDERED_EP_CONFIG compile time option to the CDC class bootloader, to reduce the compiled binary size, as the endpoint initialization order is fixed in the code.

Readd incomplete MIDIToneGenerator project, which can now correctly generate up to three simultaneous notes from MIDI channel 0.

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.

Rename new CDC class bootloader NO_LOCK_BYTE_SUPPORT compile time option to NO_LOCK_BYTE_WRITE_SUPPORT as reads are still permitted.

Clean up CDC bootloader command processing code.

Added new NO_BLOCK_SUPPORT, NO_EEPROM_BYTE_SUPPORT, NO_FLASH_BYTE_SUPPORT and NO_LOCK_BYTE_SUPPORT compile time options to the CDC class bootloader.

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.

Added new NO_SOF_EVENTS compile time option, enabled in the bootloaders to reduce the compiled binary size.

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.

Fixed incorrect LEDs_ChangeLEDs() function in the Benito board LED driver.

Added CDC functional descriptor structs to the Low Level CDC demos and CDC class bootloader, to improve the readability of the descriptors.

Fixed BootloaderCDC project failing on some operating systems due to removed Line Encoding options (thanks to Alexey Belyaev).

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).

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

Fixed software application start command broken in the DFU class bootloader when dfu-programmer is used due to application start address corruption.

Re-add deleted linker options to the Bootloader makefiles, which was preventing the compiled application from being shifted into the bootloader section address space.

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.

Add the formula used to obtain the bootloader start address to the Bootloader makefiles to help users compute the correct address for each device based on the bootloader section size.

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.

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.
