Overdrive II 1.8.6 €?

Arduino 1.8.6 is the first non-beta Arduino IDE to support parallel compile. If your computer has a quad-core processor, when rebuilding all files, Arduino may compile up to 4 pieces of code at the same time. Usually the speed increase is much less than 4 times faster, but still it manages to compile code in much less time than running every compiler process 1 at a time.
