Removed two-step endpoint/pipe bank clear and switch sequence for smaller, faster endpoint/pipe code.

Added spacing between multiple paragraphs in Doxygen \note sections.

Removed call to the clock prescaler reset function in the Teensy bootloader to save space - the user application is accessed via a watchdog reset anyway, so the prescale reset would only affect the speed of the bootloader itself.

Remove accidentally duplicated model-specific peripheral driver files.

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

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.

Make SPI and USART peripheral dispatch driver headers in preparation for a set of AVR32 peripheral drivers.

Fixed accuracy of the SERIAL_UBBRVAL() and SERIAL_2X_UBBRVAL() macros for higher baudrates (thanks to Renaud Cerrato).

Add more include protection macros to give the user warnings when they try to manually include private driver header files, instead of the public driver headers.

Fixed SerialStream driver blocking while waiting for characters to be received instead of returning EOF.

Fixed incorrect values of USB_CONFIG_ATTR_SELFPOWERED and USB_CONFIG_ATTR_REMOTEWAKEUP tokens (thanks to Claus Christensen).

Mark the AVRISP-MKII project descriptors as being both Bus Powered and Device Powered.

Copy over file level documentation of the peripheral drivers to the module level documentation.

Clean up Webserver project - add more Doxygen documentation for the new DHCP client functions and defines.

Fix TemperatureDataLogger and Webserver project builds.

Added explicit ADC channel masks for the standard set of ADC channels, as the single-ended channel MUX masks are not equal to the channel number on some AVR models. Changed demos to use the new channel masks when using the ADC driver.

Changed XPLAINBridge project to be both a USB to USART bridge and a PDI programmer, based on the state of a mode select pin.

Fixed a bug in the incomplete Webserver project, where the packet data was not being written to and read from the correct buffer address.

Fixed lack of support for the ATMEGA32U2 in the DFU and CDC class bootloaders

Changed incomplete Webserver project over to using the uIP timer library.

Add new TemperatureDataLogger project, a simple USB Mass Storage class Temperature Data Logger using the onboard Dataflash and Temperature sensor.

Add double banking property to LUFA powered projects in the Projects directory. Add guards to macro parameters to ensure that formulas passed as parameters don't mess up the internal macro structure.

Fixed AVRISP programmer demo -- can now connect to a target and read/write Sig/Lock/Fuse/OSCCAL bytes successfully.

Changed SPI_Init() to allow for the clock polarity and data sample modes to be set.

Changed Dataflash_Init() to no longer call SPI_Init() automatically.

Added V2Protocol handlers to the AVRISP project to enter/exit programming mode, and read/write fuses, lockbits, OSCCAL and Signature bytes.

Added ShutDown functions for all hardware peripheral drivers, so that peripherals can be turned off after use.

Added parameter directions to function parameter documentation.

Added new experimental FAST_STREAM_FUNCTIONS compile time option to speed up stream transfers at the expense of a higher FLASH consumption (needs testing to verify improved throughput).
