New BOARD value option BOARD_NONE (equivelent to not specifying BOARD) which will remove all board hardware drivers which do not adversely affect the code operation (currently only the LEDs driver).

Spell-check code/comments in the Webserver/AVRISP-MKII projects.

Enhance TemperatureDatalogger project -- add RTC capabilities so that data is logged along with the current time and date. Make logging interval configurable, set by a C# PC host application.

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

Change the AVRISP project's RESET LINE makefile tokens to AUX LINE, as it is not always used for target reset.

Remove missed timer 0 init code in the ISP protocol handler in the AVRISP project. Switch the XPROG protocol target communications handler over to using Timer 1 COMA/COMB ISRs for the two physical layers, rather than COMA/ICR1. Speed up bit-banged USART mode slightly.

Complete combining of PDI and TPI target communication code files, stub out TINY NVM controller functions.

Combine AVRISP project TPI and PDI lib directories - these protocols use the same underlying XPROG wrapper for the host-to-programmer command wrapping.

Correct include paths and makefile for the AVRISP project now that the protocol handlers are in seperate directories.

Add new HotmailNotifier project, which changes a LED's colour based on the user's unread email count as sent from Windows Live Messenger.

Slightly speed up software USART in the AVRISP project - faster parity computation, ensure received data is byte aligned when receive is complete by throwing away the start bit during reception.

Fix project text files to refer to "project" instead of "demo".

Split out NVM access code in the AVRISP project into a seperate NVMTarget.c source file and header. Make NVM register accesses use the NVM base address as set by the host, rather than using the fixed value from the XMEGA datasheet.

The AVRISP project can now enter PDI mode under both bit-bang and hardware USART connection modes, tested against the XPLAIN board hardware. Still need to complete higher level NVM access code so that the device's memories can be read and written.

Fix PDI code - must send NVM enable key least significant byte first, need to make sure Tx and Rx is switched correctly including disabling the output on the Tx line when receiving.

Fix AVRISP PDI protocol - make sure inverted masks have the appropriate parenthesis around them, make sure the BREAK command for the hardware USART has 12 clock cycles exactly. Poll NVM Enable bit in the target's STATUS PDI register with a timeout, as it is not set immediately.

Change over AVRISP project to have both hardware USART and software USART modes for the PDI protocol, when enabled. Fix up PDI initialisation routines.

Fix inverted bit-banged USART logic in the AVRISP project for PDI programming. Add a delay to the clock toggling in the AVRISP project to ensure that the programming speed does not exceed 10MHz under any conditions to satisfy the limits in the datasheet for all target voltages. Fix incorrect pin being used as the DATA in in PDI programming mode.

Document the PDI programming routines implemented so far in the AVRISP project. Add ability to selectively disable ISP programming support in addition to the existing ability to disable PDI programming support.

Started implementing the low level PDI protocol in the AVRISP project, for XMEGA device programming.

Factor out all the ISP related code into a seperate ISPProtocol set of files in the AVRISP Clone programmer project, to clearly seperate out the programming protocols when PDI programming is implemented.

Remove USE_NONSTANDARD_DESCRIPTOR_NAMES compile time token, split out standard descriptors into seperate USB_Descriptor_* and USB_StdDescriptor_* structures so that both can be used within the one project.

Add guard to the HID Host Class driver SetProtocol command, to ensure that the device supports boot protocol mode before issuing the request.

Add in new invalid event hook check targets to project makefiles to produce compilation errors when invalid event names are used in a project.

Re-add in flip, flip-ee, dfu and dfu-ee targets to project makefiles (thanks to Opendous Inc.)

Fix allowable F_CPU values comment in project makefiles.

Make AVRISP project build again - fix incorrect preprocessor directive in V2Protocol.c, fix makefile LUFA_PATH.
