Make an explicit constant name for the CMDEX bit of the target's NVM command register in the AVRISP-MKII Clone project.

Updated the AVRISP-MKII Clone programmer project to be compatible with the latest version of AVR Studio (version 5.1).

Changed the AVRISP-MKII Clone programmer project to report a fixed 3.3V VTARGET voltage on USB AVRs lacking an ADC instead of 5V to prevent warnings in AVR Studio 5.1 when programming XMEGA devices.

USB_CONFIG_ATTR_BUSPOWERED constant renamed to USB_CONFIG_ATTR_RESERVED, as this was misnamed (thanks to NXP Semiconductors).

Run wspurify script on /trunk/ and /branches/ C source files, to remove any trailing whitespace at the end of each line.

Add missing SVN eol-style property to ensure that source code line endings and converted to the native values on checkout.

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.

Add the GCC -fno-split-wide-types compile time option to some of the larger user projects to reduce the compiled application size.

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.

Replace all calls and references to _delay_ms() in the code with the architecture-agnostic Delay_MS() function.

Improve code generation for the Delay_MS() function on the AVR8 architecture when called with a constant input.

Updated the software USART code in the XPLAIN Bridge application so that the incomming bits are sampled at their mid-point instead of starting point, to give maximum reliability (thanks to Anton).

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.

Rename RingBuffer header functions and typedefs from RingBuff_* to RingBuffer_* so that it matches the header name.

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

Make a new general RingBuffer.h misc library driver, instead of the per-application LightweightRingBuff.h ring buffers. Change over projects to use the new driver.

Add ORDERED_EP_CONFIG to the device Projects (only) that use only a single class driver, or where the endpoint ordering is fixed, to save on compiled binary size.

Added new GCC_FORCE_POINTER_ACCESS() macro to correct GCC's mishandling of struct pointers.

Add DEVICE_STATE_AS_GPIOR=0 compile time option to the library projects, to reduce compiled binary size.

Fixed possible lost data in the XPLAINBridge, USBtoSerial and Benito projects when the host exceeds the packet timeout period on received packets as set by USB_STREAM_TIMEOUT_MS (thanks to Justin Rajewski).

Changed the XPLAINBridge software UART to use the regular CTC mode instead of the alternative CTC mode via the Input Capture register, to reduce user confusion.

Fixed Benito project discarding incoming data from the USB virtual serial port when the USART is busy.

Minor documentation improvements.

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.

Fixed USBtoSerial and XPLAINBridge demos discarding data from the PC if the send buffer becomes full.

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).

Rescue clock of the AVRISP-MKII moved to the AVR's OCR1A pin, so that the clock can be generated at all times when 125KHz ISP programming mode is selected.

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.
