All comments in the library, bootloaders, demos and projects have now been spell-checked and spelling mistakes/typos corrected.

Fixed MagStripe keyboard interface polling interval, increased to 4ms from 2ms to maintain compatibility with Apple MacOS X. Fixed changelog comments on the size of the track buffers when compiling for the AT90USBXXX6/7.

Fixed CDC demo not sending an empty packet after each transfer to prevent the host from buffering incomming data.

Altered Project and Bootloader makefiles so that the path to the LUFA library can be set in one place.

Corrections to Keyboard demo.

Removed AVRISP_Programmer project due to code quality concerns.

Fixed incorrect/missing control status stage transfers on demos, bootloaders and applications (thanks to Nate Lawson).

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.
