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().

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.

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.

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

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.

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.

Add new ReportType parameter to the HID class driver device callback and host report sending routines.

Renamed internal Host mode Class driver descriptor comparator callback routines so that they all start with a uniform DCOMP_{Class Abbreviation}_ prefix.

Add svn:eol-style property to source files, so that the line endings are correctly converted to the target system's native end of line style.

Device mode class driver callbacks are now fired before the control request status stage is sent to prevent the host from timing out if another request is immediately fired and the device has a lengthy callback routine.

Inlined currently unused MIDI ProcessControlRequest routine.

Added new EVENT_CDC_Device_BreakSent() event and CDC_Host_SendBreak() function to the Device and Host CDC Class drivers.

Remove incorrect Abstract Call Management class specific descriptor from the CDC demos, bootloaders and projects.

Make CDC class bootloader hard-reset the AVR when exited instead of a soft-reset. Reduce size of the TeensyHID bootloader slightly.

Fix the TeensyHID bootloader for the larger USB AVR devices, since Paul uses a different (undocumented) addressing scheme on these devices.

Removed software PDI/TPI emulation from the AVRISP-MKII clone project, as it was very buggy. PDI and TPI must now be implemented via seperate headers instead of the one unified ISP/TPI/PDI header.

Fixed INTERRUPT_CONTROL_ENDPOINT compile time option preventing other interrupts from occuring while the control endpoint request is being processed, causing possible lockups if a USB interrupt occurs during a transfer.

Fixed Host mode HID class driver not sending the correct report type when HID_Host_SendReportByID() was called and the HID_HOST_BOOT_PROTOCOL_ONLY compile time option is set.

Fixed Set Configuration requests not being stalled until the host has set the device's address.

Fixed possibility of internal signature retrieval being corrupted if an interrupt occurs during a signature byte read (thanks to Andrei Krainev).
