Fixed HID device class driver still using PrevReportINBuffer for GetReport control requests even when it has been set to NULL by the user application (thanks to Axel Rohde).

Remove the timeout period extension code from the AVRISP project, as no single command should ever exceed the maximum timeout period. Extend timeout period to 1 second per command, so that an accidental timeout will never occur.

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.

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

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.

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.

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

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

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.

Make the RFCOMM_SendFrame() function correctly generate frames from the input parameters, change addressing to use the raw DLCI address plus flags.

Better fix to avoid void pointer arithmetic in ConfigDescriptor.h to regain C++ compatibility (thanks to Michael Hennebry).

Remove void* arithmetic in the USB_GetNextDescriptor() static inline function, to make the header file C++ compatible once again. Implement workaround for an obscure GCC bug which can cause incorrect code generation under some circumstances when the void* is re-cast.

Partial fix to the Bluetooth SDP code - data should be encoded in big endian, not little endian.

Added new VTARGET_REF_VOLTS and VTARGET_SCALE_FACTOR compile time defines to the AVRISP-MKII programmer project to set the VTARGET reference voltage and scale factor.

Fixed XPLAINBridge project not correctly reading the XMEGA's supply voltage when reporting back to the host.

Replace ring buffer library in Benito and USBtoSerial projects with the new lightweight ring buffer header to improve reliability.

The EEPROM stream read/write functions now use eeprom_update_byte() instead of eeprom_write_byte(), so that only changed bytes are written to EEPROM to preserve its lifespan.

Changed over the AVRISP-MKII and TemperatureDataLogger projects to use eeprom_update_byte() when writing non-volatile parameters to EEPROM to preserve its lifespan.

The RingBuff library code has been replaced in the XPLAINBridge project with an ultra lightweight buffer to help  improve the reliability of the bridge.

Fixed RNDISEthernet demos crashing when calculating checksums for Ethernet/TCP packets of more than ~500 bytes due to an overflow in the checksum calculation loop (thanks to Kevin Malec).

Removed string Attributes from the Service Discovery Protocol code to minimise the potential points of failure while the base code is being debugged.

Oops - when adding a sequence header to the SDP response, the size value needs to be cleared, not the buffer pointer.

Fixed AVRISP project not sending a full erase-and-write EEPROM command to XMEGA targets when writing to the EEPROM instead of the split write-only command (thanks to Tim Margush).

Fixed AVRISP project sending a LOAD EXTENDED ADDRESS command to 128KB AVRs after programming or reading from the last page of FLASH.

Remove incorrect check for the current device state in the Set Configuration request handler of DevChapter9, which broke Set Configuration requests to the device under most circumstances.

Move out the SPI prescaler list to a PROGMEM module-level variable in ISPTarget.c.

Fixed AVRISP-MKII clone project not correctly issuing SET EXTENDED ADDRESS commands when the extended address boundary is crossed during programming or readback (thanks to Gerard Sexton).

Fixed warnings when building the AVRISP-MKII clone project with the ENABLE_XPROG_PROTOCOL compile time option disabled.
