Alter the ring buffer library headers to have both atomic and non-atomic insertion/removal routines. Modify the existing projects so that buffer operations performed in an ISR use the shorted non-atomic versions, as they are already performed in a blocking ISR.

Alter USBtoSerial demo so that it does not enter a blocking loop to send data from the USB to the USART, as this can cause dropped bytes in the reception code if large amounts of data are sent in both directions at the same time. Added a flush timer to the USBtoSerial code for the USART to USB interface, so that multiple bytes can be sent in the same USB packet.

Add glitch protection to the software UART in the XPLAINBridge project code, so that very short glitches on the RX line don't cause a frame reception to occur.

Major changes to the XPLAINBridge software UART code for performance and reliability. New code reduces the number of missed characters and misread characters.

Oops - ACL layer Bluetooth_SendPacket() function should check and allow NULL channels, since that indicates a control channel request.

Fix up Doxgen documentation for the Bluetooth stack code.

Rename Bluetooth stack function parameters to clearly indicate what sort of Bluetooth channel (ACL, RFCOMM) is required for each parameter, to make the code easier to read.

Add a new RFCOMM_ChannelSignalsReceived() Bluetooth stack callback from the RFCOMM layer for when the remote device sends new terminal control signals.

Fix RFCOMM_SendData() not aborting correctly when the requested RFCOMM channel is not found.

Rewrote the implementation of the SwapEndian_16() and SwapEndian_32() functions so that they compile down in most instances to minimal loads and stores rather than complicated shifts.

Fixed SCSI.c implementations of all the demos/projects casting the block count to a 32-bit temporary before calling SwapEndian_16().

Add a new RFCOMM_ChannelOpened() callback event for when logical RFCOMM channels are opened in the BluetoothHost demo. Make the demo echo back sent characters to the remote device.

Move out Bluetooth stack callback functions to a seperate BluetoothEvents.c/.h set of files for clarity in the Incomplete BluetoothHost demo. Add a new stack callback for opened ACL channels, make the demo save the RFCOMM channel when opened so that it does not have to search for it on each iteration of the main program loop.

Improve commenting of the Dataflash stub board driver file, to prevent confusion of what the dataflash selection masks need to be. Update stub driver to automatically interleave data between the chips if two Dataflash chips are present.

Added new Drivers/USB/LowLevel/Device.c file to house Device mode specific functions that are more complicated than simple macros. Moved USB_Device_SendRemoteWakeup() to the new Device.c source file and corrected it to unfreeze and restart the USB controller clock before issuing a Remote Wakeup request.

Removed the USB_Device_IsRemoteWakeupSent() and USB_Device_IsUSBSuspended() macros, as they are now obsolete.

Move out RFCOMM channel structure init code to a seperate routine, to save on compiled code space and to prevent copy-paste errors.

Add RFCOMM service routine, to send pending configuration requests on RFCOMM channels. Add in RFCOMM channel config flags, to determine which configuration commands have been sent and received.

Add a new RFCOMM_SendChannelSignals() function to transmit a change in V24 terminal handshake lines to the receiving device.

Prevent SABM packets sent to the control DLCI in the RFCOMM layer from creating a new channel entry, as the control DLCI does not have connection data associated with it.

Fix up MSC control packet handling so that received responses can be acknowledged correctly, so that the RFCOMM layer can record when the receiving device has ACKed a sent change in V24 terminal handshake lines.

Make Bluetooth ACL channel searches skip over closed (invalid) channels. RFCOMM channels are considered invalid when the channel state is closed, not when the DLCI is zero - fix incorrect code.

Make loops in AVRISP-MKII Clone project's XPROG protocol infinite rather than looping on the timeout value, as this is already checked inside the loop anyway.

Fix Doxygen formatting of parameters for the CALLBACK_HID_Device_CreateHIDReport() function in the ClassDriver HID device demos.

Make XPLAINBridge serial bridge much more reliable for the reception of characters from the XMEGA through the software UART interface.

Maximise the size of the ring buffers in the Benito/XPLAINBridge/USBtoSerial projects, so that they should never become full under normal conditions.

Split RFCOMM channel signals into Remote and Local pairs. Use memcpy() to copy over data from the command parameters to the RFCOMM response parameters.

Ensure that only the valid parameter bytes are sent back in response to MSC commands.

Add TEST RFCOMM command handler. Remove the RFCOMM channel UseUIFrame element, as the Bluetooth adaptions to RFCOMM only allow UIH frames to be used.

Use a bitmask instead of an array of bools in the SDP UUID List matching algorithm to reduce the compiled code size and stack used.

Added new SWAPENDIAN_16() and SWAPENDIAN_32() macros to Common.h for statically initialized variables at compile time.

Moved calls to V2Params_UpdateParamValues() out of the main AVRISP-MKII and XPLAINBridge project loops and into the AVRISP management function.

Minor tweaks to the library documentation.

Spell check code and manual pages. Remove custom Doxygen CSS stylesheet, as the new 1.7 Doxygen's default stylesheet is much better.

Rename RFCOMM_GetFrameDataLength() to RFCOMM_GetVariableFieldValue() as it is multi-purpose, and modify it to move the buffer pointer itself rather than relying on the caller.

Make RFCOMM_GetChannelData() return NULL if the required channel DLCI is found, but the channel is closed.

Add modem signals (BREAK, DCD, etc.) to the channel state array, and add in a handler for the Modem Status RFCOMM control command.

Changed the RFCOMM-specific ItemProtocolChannel_t type to a more generic ItemProtocol_8BitParam_t name, and added a new ItemProtocol_16BitParam_t to the SDP protocol type defines.

Add missing BT_* prefix to the Bluetooth stack's channel state enum values.

Fix HID parser documentation for the default maximum report/path/etc. elements so that it matches the current code values.

Split out the RFCOMM Control Channel command processing code into a seperate set of files for clarity.

Rename the incomplete Bluetooth Host demo's ServiceDiscoveryProtocol.c/.h files to SDP.c/.h. Fix compile errors in RFCOMM.c/.h.
