Cache the USB_DeviceState variable internally in the library core when multiple checks are required in a single loop iteration, to reduce compiled code size.

Revert change to the AVRISP-MKII project for fuse byte programming via the CMDEX bit - this appears to be an error in the XMEGA manual external memory programming table.

Fixed broken FLASH/EEPROM programming in the AVRISP-MKII clone project when writing in non-paged mode and the polling byte cannot be used.

Make Host mode Class drivers only set the class driver instance's state values once a compatible interface has been found within the device.

Fix typo in MIDI low level device demo.

Fix low level host mode demos not correctly fetching the next endpoint when an invalid interface is discarded.

Update the pipe configuration routines in the host mode class drivers so that they use the same new code to enumerate compatible devices to increase reliability. Add support to the host mode class drivers for non-sequential (but non-overlapping with other interface) pipe numbers.

Reverted Endpoint/Pipe non-sequential configuration hack, placed restriction on the configuration order instead to ensure maximum reliability.

Altered all low level device and host mode demos to ensure that endpoints and pipes are configured in ascending order properly.

Rewrote all low level host mode demos' configuration descriptor parser code to ensure that pipes are enumerated in ascending order, and to ensure maximum compatibility with devices.

Incremented all device mode demo's device descriptor revision numbers to ensure that any descriptor changes are re-fetched on machines which have enumerated previous versions.

Changed default value for the reset polarity parameter in the AVRISP-MKII project so that it defaults to active low drive.

Fixed incorrect USB_DeviceState value when unconfiguring the device without an address set.

Fixed incorrect LEDs_ChangeLEDs() function in the Benito board LED driver.

Added CDC functional descriptor structs to the Low Level CDC demos and CDC class bootloader, to improve the readability of the descriptors.

Fixed BootloaderCDC project failing on some operating systems due to removed Line Encoding options (thanks to Alexey Belyaev).

Add new CDC descriptor structs to the CDC class driver, so that the CDC demos can use human readable field names.

Rename prefix for Still Image Host class driver functions from "SImage_" to "SI_" to remain consistent with the rest of the driver.

Remove dfu-programmer program switches, to ensure maximum compatibility with all dfu-programmer versions.

Added the --suppress-bootloader-mem option to the makefile dfu target, to ensure that writes to the bootloader section of the AVR's flash memory are ignored (thanks to Axel Rohde).

Fixed incorrect command name for EEPROM memory programming in the makefile dfu-ee target.

Makefile whitespace fixes.

Fixed endpoint selection within the CALLBACK_HID_Device_CreateHIDReport() callback function causing broken GET REPORT requests.

Minor whitespace fixes.

Fixed SUSPI interrupt not being cleared during device mode enumeration, causing accidental mis-fires on re-enumeration.

Fixed JTAG_DEBUG_POINT() and JTAG_DEBUG_BREAK() macros not compiling under pure C99 standards mode.

Fixed USB_Host_ClearPipeStall() incorrectly attempting to determine the endpoint's direction from the currently selected pipe.

Minor documentation fixes.

Fix broken USB host mode due to the USB frame counter not being updated during the early enumeration steps, causing USB_Host_DelayMS() to spinloop forever.

Removed the EVENT_USB_InitFailure() event, as not specifying a USB mode to USB_Init() now defaults the controller into UID selection mode.

Make project makefiles correctly clean intermeditary build files from assembly and C++ sources (thanks to Daniel Czigany).

Fixed SET FEATURE and CLEAR FEATURE control requests directed at an unconfigured endpoint causing request timeouts.

Modified PRNT_Host_USBTask() to flush the output pipe on each call.

Added new project makefile template to the library and moved board driver stub files into in a new CodeTemplates directory.

Added LEDs_ToggleLEDs() function to several board LED drivers which were missing it (thanks to Andrei Krainev).

Simplify some of the LED driver functions to produce more compact code.

Added new PRNT_Host_BytesReceived() and PRNT_Host_ReceiveByte() functions to the Print Host Class driver.

Added new USB_Device_GetFrameNumber() and USB_Host_GetFrameNumber() functions to retrieve the current USB frame number.

Added new USB_Host_EnableSOFEvents(), USB_Host_DisableSOFEvents() and EVENT_USB_Host_StartOfFrame() for the user application handling of USB Start of Frame events while in USB Host mode.

Changed over all demos, drivers and internal functions to use the current frame number over the Start of Frame flag where possible to free up the Start of Frame flag for interrupt use in the user application.

Reduced HOST_DEVICE_SETTLE_DELAY_MS to 1000ms down from 1500ms to improve device compatibility while in USB Host mode, as some devices will drop off the USB bus if no connection is made within a timeout period.

Added board hardware driver support for the Olimex AVR-USB-162 development board (thanks to Steve Fawcett).

Fix incorrect ADC driver documentation for the parameters of ADC_Init(), fix incorrect call to ADC_Init() in the TemperatureDatalogger project.

Fix up documentation - remove obsolete Scheduler Overview page, roll documentation into the documentation for the (deprecated) Simple Scheduler module.

Fixed LowLevel PrinterHost demo not sending control requests to the attached printer with the correct printer interface wIndex value.
