Small tweaks to ConfigDescriptor.c/.h to ensure pointers use the correct type, and to remove const attribute from the descriptor comparator callback function pointer type define, and into the function prototype instead.

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.

Switch software UART over to timer 1 and remove timer prescaling to try to prevent integer rounding errors and thus minimize the possible error of the UART code.

Rename software USART driver globals to make the code more in line with the rest of the XPLAINBridge project.

Make software USART used in the XPLAINBridge project directly check and store into the ring buffers, rather than polling from the main program loop to avoid added latency.

Create a new LightweightRingBuffer.h header file for the XPLAIN project to abstract out the new ring buffer without a performance penalty.

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.

Add UUID Class matching to the Service Discovery Protocol code - SDP is now correctly matched against the generic Service Discovery Class UUID.

SDP Service improvements; fixed UUID for SDP service, added Service Discovery Server UUID, better documentation.

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

Service Discovery ServiceSearchAttribute requests require the response to be grouped by UUID, so the response can't be generated as the attributes are read in. Buffer both UUIDs and Attributes instead and generate the response afterwards.

Short UUIDs are measured in bytes, not bits -- update Service Discovery Protocol code so that it can now correctly match against UUIDs in the service table.

More SDP code improvements - responses to ServiceSearchAttribute service discovery requests should now be valid, even if they do not currently return the device's services and service attributes.

Added more documentation to the incomplete Bluetooth stack code.

Renamed CDC device class demos' ManagementEndpoint descriptor to NotificationEndpoint to more accurately indicate its purpose.

Switch over the BluetoothHost demo's Service Discovery code to pass around more generic GUID arrays.

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.

Fixed possible device lockup when INTERRUPT_CONTROL_ENDPOINT is enabled and the control endpoint is not properly selected when the ISR completes.

The LIBUSB_FILTERDRV_COMPAT compile time option in the XPLAINBridge and AVRISP-MKII projects has been renamed LIBUSB_DRIVER_COMPAT, as it applies to all software on all platforms using the libUSB driver.

Fix Benito makefile which was accidentally changed during testing.
