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.).

Fixed Mass Storage Host Class driver and Low Level demo not clearing the error condition if an attached device returns a STALL to a GET MAX LUN request (thanks to Martin Luxen).

Fix double oops -- Host mode settle delay was still being ignored due to inverted logic, HID Parser was assigning the usage Min/Max usage value to the report item's collection path rather than the report item itself.

Oops - fix Host mode pre-enumeration settle delay being ignored leading to failure to enumerate certain devices.

Fixed HID Parser not distributing the Usage Min and Usage Max values across an array of report items.

Added new HID_ALIGN_DATA() macro to return the pre-retrieved value of a HID report item, left-aligned to a given datatype.

Added new PreviousValue to the HID Report Parser report item structure, for easy monitoring of previous report item values.

Added CDC_Host_Flush() function to the CDC Host Class driver to flush sent data to the attached device.

Simplified the USB.h master include file's target validity checks.

Add to the existing CDC Class Driver's CreateStream() function documentation to explicitly state that the created streams are bidirectional.

Better checking of whether a packet is received in the RNDISEthernetHost Class driver demo - show busy LED status while packets are being printed out.

Correct CDC Host Class driver token handling for sending data on bidirectional data endpoints.

Remove documentation of deleted parameters from the RNDIS Host Class driver's device Initialize function.
