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

Fix byte ordering of UUIDs in the SDP server - host can now successfully pair to the Bluetooth device and discover the exposed Serial Port Profile RFCOMM service.

The SDP UUID lists should be searched and ALL UUIDs matched for a record to be retrieved, not partial matches. Change the SDP code so that the entire list must be matched against a service attribute table's contents before it is returned.

Change matching algorithm so that it recursively searches through the entire attribute table, and not just pre-specified sequence attributes.

Add browse lists and proper descriptions to the Serial Port service.

Add L2CAP service attribute table. Fix up ProtocolDescriptorList attributes, and add macros for used UUIDs to reduce typing and make the code easier to read.

Remove incorrect Language ID offset attribute from the SDP server - client assumes 0x0100 offset for primary language anyway, and the format of the offset was incorrect anyway.

Service Attribute SDP requests should have only one Data Element Sequence container around the single service's retrieved attributes, not two.

Much faster attribute range lookup - look through short list of attributes and compare to range, rather than looking up by each possible value within the range.

Cleanups to SDP code. Add missing RFCOMM language base ID offset attribute. Fix incorrect definition of the SWAPENDIAN_32() macro.

Fix endianness issues in the Service Discovery Protocol service of the incomplete Bluetooth Host demo. Host can now correctly retrieve specific services, however Windows does not appear to be sending the appropriate generic browse class IDs needed to report the virtual serial service.

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.

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.
