Add Link Key Request event processing so that paired devices always re-authenticate until appropriate link key store/retrieve callbacks are implemented.

Add LUFA-side channel open/close routines, add signalling handlers for the creation and configuration of channels from the local device to the remote device, to add to the existing remote to local channel capabilities.

Bluetooth demo can now create and maintain logical channels - need to determine why Windows machines refuse to connect.

Make Bluetooth signalling handler routines use the generic Bluetooth_SendPacket() routine for their responses. Use a better method of controlling the debug output verbosity.

Add bidirectional channel configuration -- remote device is not ACKing sent Configuration Requests, needs further debugging. Implement Bluetooth spec's channel states.

Use abbreviations for the structure and function names where possible to try to cut down on the code verbosity.

Ensure that the AVRISP-MKII project's Windows avrdude compatibility define is named properly in all parts of the code.

Add Bluetooth connection request/complete/disconnection callbacks.

Remove debugging from HCI layer, as it is now operational -- add guards to ACL debug statements to reduce logging chattyness so that the overall command sequences can be observed and debugged.

Add user callback function to the Bluetooth host demo to filter out connections from remote devices. Add in ability to reject connections based on their bluetooth device address.

Clean up RelayBoard project code.

Make AVRISP project clear the XMEGA target's reset register twice; this does not appear to take affect properly the first time under some circumstances.

Remove unused macro in the host mode demos for the maximum Configuration Descriptor size.

Massive cleanups to the incomplete BluetoothHost demo, to make the HCL layer code much easier to read, block less and work correctly.

Remove accidentally duplicated model-specific peripheral driver files.

All Class Driver Host mode demos now correctly set the board LEDs to READY once the enumeration process has completed.

Fixed Still Image Host class driver not resetting the transaction ID when a new session is opened, fixed driver not sending a valid session ID to the device.

Standardized the naming scheme given to configuration descriptor sub-elements in the Device mode demos, bootloaders and projects.

Fix errors in the MouseHostWithParser demo from incorrect use of the HID_ALIGN_DATA() macro.

Fixed PDI programming mode in the AVRISP programmer project not exiting programming mode correctly (clear target Reset key twice, set /RESET pin to pullup).

Add newlines to the MIDI event printf() statements in the MIDI host demos.

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.

New BOARD value option BOARD_NONE (equivelent to not specifying BOARD) which will remove all board hardware drivers which do not adversely affect the code operation (currently only the LEDs driver).

Spell-check code/comments in the Webserver/AVRISP-MKII projects.

Removed the stream example code from the Low Level VirtualSerial demos, as they were buggy and only served to add clutter.

Fix up project documentation files' overview tables, so that multiple items occupy multiple lines in the same cell, rather than multiple cells.

Fix Doxygen configuration files' input file exclusion filters.

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

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.

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.).

Make sure that USB_STREAM_TIMEOUT_MS is set in the MassStorageHost ClassDriver demo, so that slow devices don't time out the data pipe. Increase pipe timeout in both MassStorageHost demos to 5 seconds to account for the really slow devices.

Fix TeensyHID bootloader not properly shutting down the USB interface to trigger a disconnection on the host before resetting the AVR.

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).

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.
