Use the framework provided GlobalInterruptEnable() function instead of the AVR8/XMEGA specific sei() macro, for future demo/project portability.

Add error message for debugging purposes to the low level AudioInputHost and AudioOutputHost demos, if the request to set the audio sample rate fails.

Make CPPCheck tool happy by altering the program flow in the low level keyboard example, so that the SendReport variable is not overwritten before its first read access.

Fixed missing Win-32bit compatibility sections in the LUFA INF driver files (thanks to Christan Beharrell).

Upgrade Doxygen configuration files, custom style CSS and DOXYGEN build module for the latest Doxygen release.

Add help text to the project makefiles to help new users get information on the improved build system.

Use immediate variable expansion in the second-deepest level makefile scripts to prevent multiple evaluation of the PROJECT_DIRECTORIES variable.

Rename build system module makefiles from "lufa.MODULE.in" to "lufa_MODULE.mk" to prevent makefile from assuming the include is an old style build rule, slowing down the build process.

Prevent the BUILD module from shell-executing multiple processes to determine the avr-size flags to speed up the build, unless the size rule is invoked.

Add warnings and set warnings as errors to the SingleUSBModeTest build test makefile.

Fix project makefiles - remove trailing slash from LUFA_PATH entries and the XPLAINBridge project AVRISP file include path to prevent build errors.

Override the OBJDIR setting for the XPLAINBridge project, as this currently doesn't work. Turn off check-config test in the StaticAnalysisTest build test to save time - if the standard build fails this can be run manually to determine the problem cause.

Fix up makefile .NOTPARALLEL heuristics so that linear building is only enforced if no object folder set and the "all" target is run. Rename library "ConfigDescriptor.c" file to "ConfigDescriptors.c" to ensure that object filenames are unique.

Slightly better method of recursive make - use proper make dependencies to allow for parallel builds.

Update CDC driver INF files so that they should work even on systems without usbser.sys extracted by default (see MS KB entry 837637).

Fixed invalid configuration descriptor in the low level KeyboardMouse device demo (thanks to Jun Wako).

Add svn:eol-style property on all source files where it was missing. Fix line endings of all makefile, *.c and *.h files.

Minor makefile fixes - add phony targets, remove silence switch from the root makefile and add missing build modules to the ClassDriver VirtualSerial device demo.

Add OBJDIR optional build variable to the BULD build system module, to allow the user project to relocate the output object and dependency files to a different directory.

Add new ATPROGRAM build system module. Add ATPROGRAM and CPPCHECK modules to all application makefiles.

Add emergency aborts to the recursive makefiles to prevent system failures due to infinite recursion if something happens while building the project lists.

Remove legacy AS4 project files, now that they can be automatically generated by the new maintenance script.

Add missing documentation to custom BuiltTest hardware mapping files. Fix up old copyright years on some makefiles.

Additional fixes to the MIDI host driver due to not unfreezing/re-freezing pipes correctly (thanks to Michael Brown).

Upgrade Doxygen configuration files for Doxygen 1.8.1, fix broken stylesheet and footer HTML, add explicit spacing into documentation code fragments to prevent Doxygen from removing empty lines in the output.

Minor documentation adjustments to the demos, projects and bootloaders to ensure correct formatting of application device support.

Update project Doxygen and makefiles so that the resulting project documentation hides the unused version value, and uses the same HTML CSS stylesheet as the library core.

AppConfigHeaders: Make sure that in applications using an AppConfig.h configuration file, all application headers include the configuration file.

AppConfigHeaders: Move out the last of the demo/app configurations into new AppConfig.h header files.
