Add API support signature to the CDC and DFU class bootloaders, so that the application can detect the bootloader's API support.

Add missing reference to the BootloaderAPI.S source file in the DFU and CDC class bootloader AVRStudio 4 project files.

Fixed DFU class bootloader not resetting the LED pins as high impedance inputs when a software jump to the user applications is requested.

Minor bootloader tweaks; make some functions static where possible to reduce the compiled binary size, add additional comments to the makefiles.

USB_CONFIG_ATTR_BUSPOWERED constant renamed to USB_CONFIG_ATTR_RESERVED, as this was misnamed (thanks to NXP Semiconductors).

Run wspurify script on /trunk/ and /branches/ C source files, to remove any trailing whitespace at the end of each line.

Use the proper "-Wl,--undefined=BootloaderAPI_JumpTable" linker command line parameter in the bootloaders to ensure that the API jump tables are not discarded, rather than the previous C volatile pointer hack (thanks to Opendous Inc.).

Add missing SVN eol-style property to ensure that source code line endings and converted to the native values on checkout.

Removed the ENDPOINT_DESCRIPTOR_DIR_* macros in favour of the shorter ENDPOINT_DIR_* macros, which can now be used with both Endpoint_ConfigureEndpoint() and in the device descriptors.

Remove custom CDC class descriptor definitions from the CDC bootloader, and switch it to use the CDC Class Driver descriptor definitions.

Seperate out the device demos and project's configuration descriptor structure definitions to clearly indicate what descriptors belong to which interface.

Add new "checksource" target to the library makefiles, for automated source file existance checking.

Massive corrections to the project documentation and code comments, thanks to Russian translation services provided by Andrey from Microsin.ru.

Expand the documentation for each Bootloader to give sample usage instructions for the command line programmer utilities.

Fix typo in the HID class bootloader CLI programmer application usage instructions.

Minor documentation cleanups.

Modify the incomplete AudioInputHost demo for mono audio output.

Fix HID class bootloader not working on the larger USB AVRs due to the altered page addressing scheme.

Make DFU and CDC class bootloaders also toggle the LEDs on command activity in addition to the periodic flashing.

Replace all calls and references to _delay_ms() in the code with the architecture-agnostic Delay_MS() function.

Improve code generation for the Delay_MS() function on the AVR8 architecture when called with a constant input.

Renamed all low level Endpoint_Read_*, Endpoint_Write_* and Endpoint_Discard_* functions to use the number of bits instead of a symbolic size (Byte, Word, DWord) so that the function names are applicable and correct across all architectures.

Renamed all low level Pipe_Read_*, Pipe_Write_* and Pipe_Discard_* functions to use the number of bits instead of a symbolic size (Byte, Word, DWord) so that the function names are applicable and correct across all architectures.

Oops - Bootloader optimizations to GetDescriptor() don't work, as the Configuration Descriptor's header does not contain the full length of the descriptor, breaking full enumeration.

Add new ARCH option to the makefiles to (eventually) specify the target device architecture. Update non-usb peripheral drivers to reflect future multiple architecture support.

Add static keyword to all project globals whose scope should be restricted to the same module as they are declared in.

Tighten up the HID class bootloader code slightly, document that it currently exceeds 2KB of bootloader space for all models other than the Series 2 USB AVRs.

Added HID class bootloader, compatible with a modified version of the command line Teensy loader from PJRC.com.
