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

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.

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.

Add svn:eol-style property to source files, so that the line endings are correctly converted to the target system's native end of line style.

Change over instances of "make" in the makefiles to "$(MAKE)" to allow for the make tool to be overridden.

Relocate USBInterrupt.c/.h from the HighLevel USB driver directory to the LowLevel directory as it is hardware-dependent.

USB_Init() no longer calls sei() to enable global interrupts - this must now be done in the user application once all init code has run.

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.

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.

Fix up project documentation files' overview tables, so that multiple items occupy multiple lines in the same cell, rather than multiple cells.

Fix Doxygen configuration files' input file exclusion filters.

Added support to the MIDI Class drivers for packed data, where multiple MIDI events are packed into a single USB packet. Added new MIDI Class driver flush routines to override packing behaviour.

Make MIDI device demos also turn off the on board LEDs if MIDI Note On messages are sent with a velocity of zero, which some devices use instead of Note Off messages (thanks to Robin Green).

Add optional double-banking support to the Device mode Class Drivers, on a per-endpoint, per-interface level.

Fix up demo documentation device compatibility list to be as general as possible to reduce changes required as Atmel releases more devices within the same USB AVR series.

Removed mostly useless "TestApp" demo, as it was mainly useful only for checking for sytax errors in the library.

MIDI device demos now receive MIDI events from the host and display note ON messages via the board LEDs.

Added beginnings of a MIDI class bootloader.

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.

Renamed all library events to properly seperate out Device and Host mode events. Changed the firing conditions for some events to ensure that events are fired by their own USB mode only.

Remove VBUS events - not needed as the library takes care of VBUS detection and feedback on supported AVRs via the USB_Device_Connected and USB_Device_Disconnected events.

Fixed incorrect Host state assignment in the incomplete BluetoothHost demo.

Rename TOTAL_NUM_CONFIGURATIONS to FIXED_NUM_CONFIGURATIONS, to match the existing FIXED_CONTROL_ENDPOINT_SIZE compile time option. Add FIXED_NUM_CONFIGURATIONS to the descriptors of each project using the option.

Fix redefinition warning when USB_DEVICE_ONLY is set on an AVR which does not support USB host mode.

Change project makefiles so that the current target settings and not just the board selection is printed during the build process.

Fix warning in AudioOutput demos when AUDIO_OUT_STEREO output mode is selected.

State information for class drivers is now zeroed out during enumeration (both in device and host mode) to ensure sane values after each enumeration. User code should no longer explicitly set state information as this is no longer preserved.

Change Doxygen configuration files to not produce 4096 directories for the documentation files -- the LUFA components do not generate enough documentation files to justify the large performance hit of creating so many directories.

Fix missing Doxygen documentation in the Class Driver Mass Storage Device demo.

Added new TOTAL_NUM_CONFIGURATIONS option, removed USE_SINGLE_DEVICE_CONFIGURATION compile time option (but silently convert it to USE_SINGLE_DEVICE_CONFIGURATION internally for compatibility).

Added new USE_FLASH_DESCRIPTORS compile time option. By default, descriptors can now lie in mixed memory spaces (specified by a new parameter to the CALLBACK_USB_GetDescriptor() function) unless one of the USE_*_DESCRIPTORS compile time option is specified.
