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

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.

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.

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.

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.

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

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.

Fix RNDIS Device Class driver - RNDISConstants.h has moved out to the Common Class driver directory.

Fixed all Class drivers to ensure they have appropriate guards on each function to ensure the device is enumerated before running, fixed error codes on all guards to return "DeviceDisconnected" where possble.

Renamed HOST_SENDCONTROL_DeviceDisconnect enum value to HOST_SENDCONTROL_DeviceDisconnected to be in line with the rest of the library enum error codes.

Added new RNDISHost Host LowLevel demo. Fixed misnamed Pipe_SetPipeToken() macro for setting a pipe's direction. Fixed CDCHost failing on devices with bidirectional endpoints.

Added new ReportType parameter to the HID Device Class driver CALLBACK_HID_Device_CreateHIDReport() callback to indicate the report type to generate.

Fixed incorrect values for REPORT_ITEM_TYPE_* enum values causing corrupt data in the HID Host Parser.

The incomplete StandaloneProgrammer project now uses Host and Device Mass storage classes, so that program data can either be loaded onto the device's Dataflash storage, or read off an attached USB memory stick.

The USB target family and allowable USB mode tokens are now public and documented (USB_CAN_BE_*, USB_SERIES_*_AVR).

The SCSI_Request_Sense_Response_t and SCSI_Inquiry_Response_t type defines are now part of the Mass Storage Class driver common defines, rather than being defined in the Host mode Class driver section only.

The USB_MODE_HOST token is now defined even when host mode is not available.

Added missing CDC_Host_CreateBlockingStream() function code to the CDC Host Class driver.

Fix doxygen documentation - doxygen was getting confused on the variable-length ATTR_NON_NULL_PTR_ARG() macro used on  function prototypes and was generating many return types for several functions in the documentation (thanks to David Lyons).

Add new (incomplete) StandaloneProgrammer project, using the ELM Petite FAT library to read files stored on the board's dataflash by the host.

Update CDC Class Driver character stream functions to use the correct avr-libc return codes for errors and EOF.

Fix pointer arithmetic on void byte buffers by explicitly typecasting the buffer pointers to uint8_t* before altering them.
