Document the Bluetooth ACL layer. Remove unneeded parameters from the signalling command processing routines.

Change over the code so that the bluetooth packet data is read in by the stack rather than the user application, to make it more unform for sending/receiving, and so the library can handle incomming fragmentation in the future.

Start Service Discovery Protocol decoding and processing.

Add some more documentation to the half-completed Bluetooth Host demo, fix the OpenChannel() command initialising the channel information structure to the wrong initial state once the CONNECTION REQUEST command has been sent to the remote device.

Fix Bluetooth stack CONNECTION RESPONSE packets - for this command and this command only, the source/destination roles are switched. Reverse the Local/Remote channel ordering so that Windows mobile and other stacks which depend on valid channel values to connect.

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.

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.

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.).

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.

Fixed LowLevel Keyboard demo not saving the issued report only after it has been written to the endpoint.

Added support for multiple keyboard keycodes in a single report to the LowLevel and ClassDriver Keyboard demos.

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

Change device demos which use the joystick to use the natural UP, DOWN, LEFT, RIGHT ordering in all demos when checking the joystick's position.

Corrected the name of the misnamed USB_GetDeviceConfigDescriptor() function to USB_Host_GetDeviceConfigDescriptor().

Extend incomplete RNDISHost demo -- can not enumerate a RNDIS device correctly and set the packet filter. No packets are received yet from the test device, need to investigate additional SET commands to see if any critical OIDs have been missed.

Make Low Level host demos use void pointers for the configuration descriptor, to prevent warnings when passed to the altered configuration descriptor parsing routines.

Added preprocessor checks to give a human readable error when the class drivers are used when the incompatible NO_STREAM_CALLBACKS compile time option is used.

Remove old OTG demo directory with useless TestApp demo. Add new DualRole directory with new Class Driver powered Mouse dual role demonstration application showing a dual role device using the HID host/device Class drivers.

Remove USE_NONSTANDARD_DESCRIPTOR_NAMES compile time token, split out standard descriptors into seperate USB_Descriptor_* and USB_StdDescriptor_* structures so that both can be used within the one project.

Add guard to the HID Host Class driver SetProtocol command, to ensure that the device supports boot protocol mode before issuing the request.

Add in new invalid event hook check targets to project makefiles to produce compilation errors when invalid event names are used in a project.

Re-add in flip, flip-ee, dfu and dfu-ee targets to project makefiles (thanks to Opendous Inc.)

Fix allowable F_CPU values comment in project makefiles.

Oops - with new changes to the way the device Configuration Descriptor is retrieved from the device, ensure that the correct position pointer is cast when extracting descriptor parameters.

Changed the parameters and behaviour of the USB_GetDeviceConfigDescriptor() function so that it now performs size checks and data validations internally, to simplify user code.

Make Endpoint control transfers more reliable; early-abort when an incomplete packet is sent from the host (indicating end of transfer), add check for control reads to ensure that no more than wLength bytes are read from the interface.

Condense sequential printf_P/puts_P calls to single printf_P calls for size and clarity.

Renamed all library events to properly seperate out Device and Host mode events. Changed the firing conditions for some events to ensure that events are fired by their own USB mode only.

Remove VBUS events - not needed as the library takes care of VBUS detection and feedback on supported AVRs via the USB_Device_Connected and USB_Device_Disconnected events.

Fixed incorrect Host state assignment in the incomplete BluetoothHost demo.
