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.

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.

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.

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.

Seperated out Lib components of the incomplete BluetoothHost demo application out into a seperate Lib subfolder.

Changed F_CLOCK entries in project makefiles to alias to F_CPU by default, as this is the most common case.

Fix makefiles -- the auto-addition of -D switches to each LUFA compile time option was faulty, due to GNUMake becomming confused by the spaces in the USE_STATIC_OPTIONS lines. Make user add in the switches explicitly instead.

Split out common defines/types from class drivers into a seperate common class driver directory.

Make central USB Class driver dispatch headers, used for both device and host modes.

Remove outdated AVRStudio project files from demos, projects, bootloaders. Fix makefiles of ClassDriver device demos.

Move new Class Driver powered demos to a new ClassDriver subdirectory, re-add old low level demos to a LowLevel subdirectory.

Add MIDI class driver, update MIDI device demo to use the new USB class driver. All device demos/projects have now been converted to the new library class drivers, although documentation is yet to be completed.

Commit of new class abstraction APIs for all device demos other than the MIDI demo - not documented yet.

Removed scheduler and memory allocation libraries.

Added new EVENT_USB_StartOfFrame event in the library to indicate the start of each USB frame (when generated).

Removed Tx interrupt from the USBtoSerial demo; now sends characters via polling to ensure more time for the Rx interrupt.

Deleted StdDescriptors.c, renamed USB_GetDescriptor() to CALLBACK_USB_GetDescriptor, moved ConfigDescriptor.c/.h from the LUFA/Drivers/USB/Class/ directory to LUFA/Drivers/USB/HighLevel/ in preperation for the new USB class APIs.

Fixed incorrect ENDPOINT_EPNUM_MASK mask preventing endpoints above EP3 from being selected (thanks to Jonathan Oakley).

Removed STREAM_CALLBACK() macro - callbacks now use regular function definitions to clarify user code.

Removed DESCRIPTOR_COMPARATOR() macro - comparators should now use regular function definitions to clarify user code.

Changed PIPE_CONTROLPIPE_DEFAULT_SIZE from 8 to 64 to try to prevent problems with faulty devices which do not respect the given wLength value when reading in the device descriptor.

Further documentation improvements - removed file view from the main library documentation, replaced file references in the documentation with group references.

Endpoint configuration is now refined to give better output when all configurations have static inputs - removed the now useless STATIC_ENDPOINT_CONFIGURATION compile time token.

Applied STATIC_ENDPOINT_CONFIGURATION and FIXED_CONTROL_SIZE tokens to all Device mode demos to reduce binary size.

More documentation changes for better module-level documentation rather than file-level documentation.

Seperated out OTG, Device and Host mode demos into seperate folders for clarity. Adjusted makefiles so that the path to the LUFA library can be set in one place.

Updated makefiles to reflect new dfu-ee programming target invocations (supplied by Opendous, Inc.).

Renamed the ATTR_ALWAYSINLINE function attribute macro to ATTR_ALWAYS_INLINE to match the style of the other function attribute macro names.

Added ATTR_ALWAYS_INLINE attribute to several inlined library functions, to ensure they are inlined in all circumstances.

Cleanups to Endpoint.h and Pipe.h. Added better documentation for the endpoint and pipe interrupts.

Makefiles and library modified to add a new F_CLOCK constant to give the unprescaled master input clock frequency, so that the correct PLL mask can be determined even when the CPU (F_CPU) clock rate is prescaled outside the normal input range of the PLL.

Started to clean up the AVRISP Programmer project code, donated by Opendous Inc.
