Clarify in the project documentation files what the each of the different USB AVR device "series" comprises of.

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

Changed the signature of the CALLBACK_USB_GetDescriptor() callback function so that the descriptor pointer is const, to remove the need for extra casting inside the callback (thanks to Jonathan Kollasch).

Added compile time error to the AVRISP-MKII project when built for the U4 chips, as the default VTARGET detection ADC channel does not exist on these chips (thanks to Marco).

Removed complicated logic for the Endpoint_ConfigureEndpoint() function to use inlined or function called versions depending of if the given bank size is a compile time constant, as the compiler does a better job of optimizing with basic code.

Changed over all device demos to use a clearer algorithm for the configuring of the application's endpoints.

Fix invocations of avr-size in all makefiles broken on unpatched *nix systems, due to the recent update to the latest WinAVR makefile template.

Invert the logic for the VBUS power light in the AVRISP-MKII project for the USBTINY-MKII board target.

More spell checking of all source files -- correct missed errors, switch to EN-GB spelling dictionary.

Add special support to the AVRISP-MKII for the new model USBTINY-MKII's additional LED to indicate target power source.

Add support to the USBTINY-MKII's additional LED in the board's LED driver header.

Changed LED indicator masks for the AVRISP-MKII project, so that there are defined roles for each LED.

Remove obsolete macros and preprocessor checks from the AVRISP-MKII project's V2Protocol command handler header file.

Added support to the AVRISP-MKII project for ISP speeds slower than 125KHz via a new software SPI driver.

Added new SPI_ORDER_* data order masks to the SPI peripheral driver.

Future proof the XPROG protocol of the AVRISP-MKII project, so that non PDI and TPI requests return failure.

Update all demos, projects and bootloaders to indent all function parameters, one per line, for better readability.

Add missing const qualifiers to the demos.

Add new module source variables to the library core makefile, so that module sources can be added to a project's makefile on a per-module rather than per-file basis.

Disable strict aliasing explicitly in the project makefiles, as this is apparently enabled by default in newer AVR-GCC builds, and aliasing is used heavily for type-punning through the LUFA and third party library's codebase.

Removed the automated checking of event names in the demo, project and bootloader makefiles due to inconsistancies between the behaviour of the command line tools used to perform the check on each platform.

Removed the internal endpoint and pipe memory allocation macros, as this is already performed directly in the code. Simplify the endpoint and pipe reset procedure.

Change AVRISP-MKII and XPLAINBridge descriptors to indicate that the device is bus-powered only. Add compile time options to reduce the compiled size of the firmware.

Remove the timeout period extension code from the AVRISP project, as no single command should ever exceed the maximum timeout period. Extend timeout period to 1 second per command, so that an accidental timeout will never occur.

Rename the AVRISP main source files to AVRISP-MKII so that it matches the project name. Add AVRStudio project file for the AVRISP-MKII project.

Move out Bluetooth stack callback functions to a seperate BluetoothEvents.c/.h set of files for clarity in the Incomplete BluetoothHost demo. Add a new stack callback for opened ACL channels, make the demo save the RFCOMM channel when opened so that it does not have to search for it on each iteration of the main program loop.

Added new Drivers/USB/LowLevel/Device.c file to house Device mode specific functions that are more complicated than simple macros. Moved USB_Device_SendRemoteWakeup() to the new Device.c source file and corrected it to unfreeze and restart the USB controller clock before issuing a Remote Wakeup request.

Removed the USB_Device_IsRemoteWakeupSent() and USB_Device_IsUSBSuspended() macros, as they are now obsolete.

Make loops in AVRISP-MKII Clone project's XPROG protocol infinite rather than looping on the timeout value, as this is already checked inside the loop anyway.

Moved calls to V2Params_UpdateParamValues() out of the main AVRISP-MKII and XPLAINBridge project loops and into the AVRISP management function.

Spell check code and manual pages. Remove custom Doxygen CSS stylesheet, as the new 1.7 Doxygen's default stylesheet is much better.

Reduce the size of the attribute search list from 15 ranges to 8 to save RAM.

Added new VTARGET_REF_VOLTS and VTARGET_SCALE_FACTOR compile time defines to the AVRISP-MKII programmer project to set the VTARGET reference voltage and scale factor.

Fixed XPLAINBridge project not correctly reading the XMEGA's supply voltage when reporting back to the host.

The EEPROM stream read/write functions now use eeprom_update_byte() instead of eeprom_write_byte(), so that only changed bytes are written to EEPROM to preserve its lifespan.

Changed over the AVRISP-MKII and TemperatureDataLogger projects to use eeprom_update_byte() when writing non-volatile parameters to EEPROM to preserve its lifespan.

The RingBuff library code has been replaced in the XPLAINBridge project with an ultra lightweight buffer to help  improve the reliability of the bridge.

Short UUIDs are measured in bytes, not bits -- update Service Discovery Protocol code so that it can now correctly match against UUIDs in the service table.
