Starting with Arduino 1.0 (December, 2011), NewSoftSerial has replaced the old SoftwareSerial library as the officially supported software serial library. This means that if you have 1.0 or later, you should not download this library. To port your code to 1.0, simply change all NewSoftSerial references to SoftwareSerial. NewSoftSerial is the latest of three Arduino libraries providing “soft” serial port support.
