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.

Renamed all low level Endpoint_Read_*, Endpoint_Write_* and Endpoint_Discard_* functions to use the number of bits instead of a symbolic size (Byte, Word, DWord) so that the function names are applicable and correct across all architectures.

Renamed all low level Pipe_Read_*, Pipe_Write_* and Pipe_Discard_* functions to use the number of bits instead of a symbolic size (Byte, Word, DWord) so that the function names are applicable and correct across all architectures.

Endpoint_ResetFIFO() renamed to Endpoint_ResetEndpoint(), to be consistent with the Pipe_ResetPipe() function name.

Fix undefined error in Pipe_UC3B.h.

Add missing migration notes.

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.

Oops - fix up some calls to the old function names, include Serial Peripheral driver in the RNDISEthernetHost project.

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.

Oops - forgot to add in LOGICAL MINIMUM and LOGICAL MAXIMUM report items into the standard library Joystick HID report descriptor macro. Add in support for joystick resolution reporting via PHYSICAL_MINIMUM and PHYSICAL_MAXIMUM items.

Add new HID_DESCRIPTOR_VENDOR() macro, change over all projects and Device ClassDriver demos to use it.

Fix reversed byte ordering of multi-byte HID data.

Added support to the HID parser for extended USAGE items that contain the usage page as well as the usage index.

Removed the HID_IOF_NON_VOLATILE and HID_IOF_VOLATILE flags from HID INPUT items where the flag is invalid. Changed over HID OUTPUT items to use HID_IOF_NON_VOLATILE.

Change over MagStripe project to use HID_DESCRIPTOR_KEYBOARD() for its HID report. Change over MouseHostDevice demo to use HID_DESCRIPTOR_MOUSE() for its HID report.

Fixed ReportID not being removed from the feature/out report data array in the HID class driver when Report IDs are used.

Added new MAX() and MIN() convenience macros.

Added new HID_DESCRIPTOR_MOUSE, HID_DESCRIPTOR_KEYBOARD and HID_DESCRIPTOR_JOYSTICK macros for easy automatic creation of  basic USB HID device reports.

Change over Joystick demo HID report descriptor to use USAGE_MINIMUM and USAGE_MAXIMUM when describing the joystick buttons, to allow for easy extension of the number of supported buttons.

Abuse the the C preprocessor so that the HID macros can automatically encode data into the array from the HID macros automagically, by specifying the bit-width of the data, and the data itself as a single integer value of that width.

New HID report item macros (with HID_RI_ prefix) to allow for easy creation and editing of HID report descriptors.

Changed over all project and demo HID report descriptors to use the new HID report item macros.

Moved the HIDParser.c source file to the LUFA/Drivers/USB/Class/Common/ directory from the LUFA/Drivers/USB/Class/Host/.

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

Spell check source code files.

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.

Fixed incorrect endpoint initialisation order in the LowLevel DualVirtualSerial demo (thanks to Rick Drolet).

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).

Fixed calculation of timer register reload values derived from F_CPU; must subtract one from the division result for the compare value to be correct.

Change AVRISP-MKII rescue clock speed to 4MHz to ensure that a 125KHz ISP speed works regardless of the target's fuses (i.e. DIV8 set).

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

Loop in the ClassDriver MIDI device/host demos until there are no more incomming events to process. Only clear the endpoint/pipe bank in the LowLevel MIDI device/host demos when the endpoint is empty after an event read.

Fix XPLAINBridge code broken during the changes to the Rescue Clock generation in the AVRISP-MKII clone project.

Change over all low level host mode project's descriptor comparator routines to perform the descriptor casting in a temp variable to make the code clearer and easier to modify (despite being more verbose).

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.
