Add button support for the BENITO board target.

Remove accidentally duplicated model-specific peripheral driver files.

All Class Driver Host mode demos now correctly set the board LEDs to READY once the enumeration process has completed.

Fixed Still Image Host class driver not resetting the transaction ID when a new session is opened, fixed driver not sending a valid session ID to the device.

Added hardware board driver support for the PJRC Teensy line of USB AVR boards.

Fixed compilation error in the AudioInput demos when MICROPHONE_BIASED_TO_HALF_RAIL is defined (thanks to C. Scott Ananian).

Minor documentation cleanups.

Make sure HID class driver uses properly cast pointers when writing to the report buffer.

Standardized the naming scheme given to configuration descriptor sub-elements in the Device mode demos, bootloaders and projects.

Fix errors in the MouseHostWithParser demo from incorrect use of the HID_ALIGN_DATA() macro.

Double bank CDC endpoints in the XPLAIN Bridge project, re-enable JTAG once the mode selection pin has been sampled.

Increased throughput of the USBtoSerial demo on systems that send multiple bytes per packet (thanks to Opendous Inc.).

Don't enable the pullup on the target /RESET line in the AVRISP project for PDI mode - clearing the XMEGA's reset control register twice is enough to release it from reset. Possible silicon bug, since the official Atmel programmers have the same issue.

Fixed PDI programming mode in the AVRISP programmer project not exiting programming mode correctly (clear target Reset key twice, set /RESET pin to pullup).

Add newlines to the MIDI event printf() statements in the MIDI host demos.

Fixed ADC routines failing to read the extended channels (Channels 8 to 13, Internal Temperature Sensor) on the U4 series USB AVR parts.

Added ENABLE_TELNET_SERVER compile time option to the Webserver project to disable the TELNET server if desired.

Change over static strings in the Webserver project to use PROGMEM where possible.

Fix missing text from the Host Mode States enum documentation.

Don't double-read data from the attached disk in the incomplete StandaloneProgrammer project when in host mode.

Fix TWI driver not aborting when faced with no response after attempting to address a device on the bus.

Added a timeout value to the TWI_StartTransmission() function, within which the addressed device must respond.

Fixed TWI_StartTransmission() corrupting the contents of the GPIOR0 register.

Update Temperature board driver to be AVR32 compatible when the ADC peripheral driver is eventually ported. Make architecture includes explicit for both the AVR32 and the AVR8, to make way for future architecture ports.

Add SPI driver aliases for the old function names in the AVR8 driver, so that existing code will still compile against the new version.

Fixed software PDI/TPI programming mode in the AVRISP project not correctly toggling just the clock pin.

Fix broken AVR8 Serial peripheral driver.
