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.

Added WIN_LIBUSB_COMPAT compile time option to the AVRISP programmer project to make the code compatible with Windows builds of avrdude at the expense of AVRStudio compatibility.

Oops, incorrectly edited the Benito buttons driver file instead of the JM-DB-U2 buttons driver file.

Fix up preprocessor guards in the new board driver files.

Add button support for the BENITO board target.

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.

Added hardware board driver support for the PJRC Teensy line of USB AVR boards.

Fixed compilation error in the AudioInput demos when MICROPHONE_BIASED_TO_HALF_RAIL is defined (thanks to C. Scott Ananian).

Minor documentation cleanups.

Make sure HID class driver uses properly cast pointers when writing to the report buffer.

Change over MIDIToneGenerator to use only a single channel (MIDI channel 1) due to cycle constraints.

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.

Double bank CDC endpoints in the XPLAIN Bridge project, re-enable JTAG once the mode selection pin has been sampled.

Increased throughput of the USBtoSerial demo on systems that send multiple bytes per packet (thanks to Opendous Inc.).

Don't enable the pullup on the target /RESET line in the AVRISP project for PDI mode - clearing the XMEGA's reset control register twice is enough to release it from reset. Possible silicon bug, since the official Atmel programmers have the same issue.
