Turn OFF double banking in the Webserver demo - leaving it on seems to destroy the system throughput.

Fix HID Host Class driver sending incorrect ReportType values to the device when issuing requests via the control pipe.

Add more include protection macros to give the user warnings when they try to manually include private driver header files, instead of the public driver headers.

Moved the USB_GetHIDReportItemInfo() calls into the main report item passing loop in the *HostWithParser demos - it is fast enough not to effect performance, and avoids duplicate code.

Make Webserver project report the LUFA version as part of the HTTP header.

Fix AVRISP-MKII clone project's TPI Chip Erase command processing - ensure erase location is the high byte in the given address space, check NVMBUSY for completion rather than the NVM Bus Enable bit.

Change If-Else chains over to switch statements in XPROGProtocol.c for clarity.

Replace the Webserver demo's uIP with the latest code ripped from the Contiki project by Adam Dunkels.

Fixed incorrect values of USB_CONFIG_ATTR_SELFPOWERED and USB_CONFIG_ATTR_REMOTEWAKEUP tokens (thanks to Claus Christensen).

Mark the AVRISP-MKII project descriptors as being both Bus Powered and Device Powered.

Copy over file level documentation of the peripheral drivers to the module level documentation.

Re-added Pipe_IsEndpointBound() calls to the CDC and RNDIS host class drivers, not that the function has the correct behaviour for devices with bidirectional endpoints.

Be doubly-certain that the incomming CDC class driver's endpoint/pipe is flushed only once when the bank is empty.

Fixed CDC and RNDIS host demos and class drivers - bidirectional endpoints should use two seperate pipes, not one half-duplex pipe.

Clean up and add more comments to the AVRISP-MKII project. Make sure the SPI_MULTI command handler supports multiple packet responses. Use slightly smaller/faster repeated indirect-load commands when retrieving the PDI target's memory CRCs.

Fixed lack of support for the ATMEGA32U2 in the DFU and CDC class bootloaders

Changed incomplete Webserver project over to using the uIP timer library.

Fixed incorrect interface values in the VirtualSerialMouse and KeyboardMouse demo class driver structures.

Added caveat information to the CDC device class driver.

Added support to the MIDI Class drivers for packed data, where multiple MIDI events are packed into a single USB packet. Added new MIDI Class driver flush routines to override packing behaviour.

Inline USB management functions in the Class drivers which are standardized but currently unused, to prevent them from using up unneccesary cycles and flash in the user application.

Fix MassStorageKeyboard demo USE_INTERNAL_SERIAL check being performed before the required library headers were included, causing a compilation error.

Added notes to the class driver functions indicating which functions require what Device/Host state machine states to function.

Fixed USB_CurrentMode not being reset to USB_MODE_NONE when the USB interface is shut down and both Host and Device modes can be used (thanks to Daniel Levy).

Add new HotmailNotifier project, which changes a LED's colour based on the user's unread email count as sent from Windows Live Messenger.

The SImage_Host_SendBlockHeader() and SImage_Host_ReceiveBlockHeader() Still Image Host Class driver functions are now public.

Fix a bug in the Still Image Host Class driver where the returned block status code was being truncated.

Add programming support to the AVRISP project's PDI programming mode; paged memory writes are not currently functional.

Fix inverted bit-banged USART logic in the AVRISP project for PDI programming. Add a delay to the clock toggling in the AVRISP project to ensure that the programming speed does not exceed 10MHz under any conditions to satisfy the limits in the datasheet for all target voltages. Fix incorrect pin being used as the DATA in in PDI programming mode.

Increase timeout of Mass Storage and Still Image host commands to 10 seconds (up from 5) to account for slow-processing devices.

Added brace guards to macros with parameters to prevent unintended changed evaluation of the macro expression.

Minor code cleanups (remove redundant comments, fix spacing, etc.).
