Ensure that the AVRISP-MKII project's Windows avrdude compatibility define is named properly in all parts of the code.

Add user callback function to the Bluetooth host demo to filter out connections from remote devices. Add in ability to reject connections based on their bluetooth device address.

Clean up RelayBoard project code.

Make AVRISP project clear the XMEGA target's reset register twice; this does not appear to take affect properly the first time under some circumstances.

Remove unused macro in the host mode demos for the maximum Configuration Descriptor size.

Added WIN_LIBUSB_COMPAT compile time option to the AVRISP programmer project to make the code compatible with Windows builds of avrdude at the expense of AVRStudio compatibility.

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.

Change over MIDIToneGenerator to use only a single channel (MIDI channel 1) due to cycle constraints.

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.

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.

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.

More fixes to the AVRISP command timeout system so that it should no longer lock up while processing command no matter what the conditions.

Oops - missed a few references to the old global TimeoutMSRemaining counter in ISPTarget.c of the AVRISP-MKII clone project.

AVRISP programmer project now has a more robust timeout system, allowing for a doubling of the software USART speed for PDI and TPI programming.

Use a temporary variable to hold the current URI length in the Webserver, rather than calling strlen() multiple times on an unchanged buffer. Clean up uip-split.c.

Turn OFF double banking in the Webserver demo - leaving it on seems to destroy the system throughput.

Add uIP-split code to the Webserver project, so that each packet is split in half to avoid the delayed-ACK problem when communicating with other devices. Condense HTTP server code, so that the HTTP headers are all sent from the one state. Make default filename append to any directory URI, rather than just the root directory.

Add missing TWI_Init() call to the TemperatureDataLogger project. Make DUMMY_RTC compile time option the default, so that it works correctly on the USBKEY and other Atmel boards out of the box.

Add NO_VTARGET_DETECT compile time option to the AVRISP-MKII clone project, to disable VTARGET detection on AVR models with an on-chip ADC.
