Add new USB_Host_GetDescriptor() function. Alter the USB_Host_GetDeviceDescriptor() and USB_Host_GetDeviceStringDescriptor() convenience functions so that they wrap the new function.

Add new Android Open Accessory class driver to the library core and add a new Android Open Accessory Host ClassDriver demo.

Add additional compile time errors to the XMEGA and AVR8 architectures if multiple USE_*_DESCRIPTORS compile time tokens are enabled.

Add support for the NO_INTERNAL_SERIAL compile time token on the XMEGA targets.

Fixed broken AVR32 endpoint/pipe communications when ORDERED_EP_CONFIG compile time option is not enabled (thanks to Matthias).

Fixed broken compilation for the AVR32 devices if the NO_SOF_EVENTS compile time option was not enabled (thanks to Matthias).

Added Class, ClassDevice, ClassHost and ClassCommon to the internal class driver source filenames to prevent ambiguities.

Fixed race conditions in the CDC, HID and Mass Storage class drivers when processing some control requests.

Added INVERTED_ISP_MISO compile time option to the AVRISP-MKII clone project (thanks to Chuck Rohs).

Fixed CDC class drivers not saving and sending all 16-bits of the control line states (thanks to Matthew Swabey).

Rename the Doxygen page source directory from ManPages/ to DoxygenPages/ to prevent user confusion with the actual *nix Man tool.

Added reliability patches to the AVRISP-MKII Clone project's PDI/TPI protocols (thanks to Justin Mattair).

When automatic PLL management mode is enabled on the U4 series AVR8 chips, the PLL is now configured for 48MHz and not a divided 96MHz, to lower power consumption and to keep the system within the datasheet specs for 3.3V operation (thanks to Scott Vitale).

Fix additional warnings under GCC 4.6.

Added reliability patches to the AVRISP-MKII Clone project's ISP and PDI/TPI protocols (thanks to Justin Mattair).

Fixed HID Parser's largest report size bit count not including the size of the last parsed report item.

Fixed HID host driver's largest HID report size count corrupt when the number of report bits exceeds 255.

Fixed optimization error in the HID Parser item value USB_SetHIDReportItemInfo() and USB_GetHIDReportItemInfo() routines if the report item was NULL (which should be allowable according to the API).

Fixed HID Parser CALLBACK_HIDParser_FilterHIDReportItem() callback function not being passed a cacheable report item pointer.

Renamed USB_Host_ClearPipeStall() to USB_Host_ClearEndpointStall() as the function works on an endpoint address within the attached device, and not a Pipe within the host.

Updated MS_Host_ResetMSInterface() to now perform a full Mass Storage reset sequence to prevent data corruption in the event of a device lock up or timeout (thanks to David Lyons).

Add parenthesis around the library Endianness macros that do nothing on a particular architecture to prevent operator precedence issues depending on usage.

Minor documentation corrections.

Changed the reports in the GenericHID device demos to control the board LEDs, to reduce user confusion over the callback routines.

Fixed swapped TWI_ADDRESS_READ and TWI_ADDRESS_WRITE values.

Fixed TWI_ReadPacket() not releasing the TWI bus on read completion.

Pull out architecture specific macros and other definitions into a new common header file. Add new JTAG_DISABLE() macro for the AVR8s to software-disable JTAG debugging using cycle-safe assembly code.

Add shortcuts to SwapEndian_16() and SwapEndian_32() internal functions to improve optimization if called with constant inputs.

Fixed incorrect Dataflash buffer use in the DataflashManager_WriteBlocks_RAM() function of several demos/projects (thanks to Jeremy Willden).

Added new VTARGET_USE_INTERNAL_REF configuration option to the AVRISP-MKII clone project (thanks to Volker Bosch).

Fixed USB_USBTask not being called internally in stream transfers between packets when Partial Stream Transfers are used.

Remove old unused function prototype in the LowLevel MassStorage device demo.

Removed the ENDPOINT_DESCRIPTOR_DIR_* macros in favour of the shorter ENDPOINT_DIR_* macros, which can now be used with both Endpoint_ConfigureEndpoint() and in the device descriptors.

Added Device Qualifier standard descriptor structure definitions USB_StdDescriptor_DeviceQualifier_t and USB_Descriptor_DeviceQualifier_t.
