Arduino 1.5 and Arduino Due board released

Arduino has released version 1.5 of its microcontroller programming environment, which supports easier library installation and board selection. The new release also implements compiling "sketches" for multiple processor architectures, a feature designed to support the Arduino Due board, which is also available now. The Due hardware sports a 32-bit ARM Cortex-M3 CPU in place of the 8-bit microcontrollers of previous generations, as well as USB OTG and two digital-to-analog converters (DACs).
