-#Arduino MIDI Library v4.1
+#Arduino MIDI Library v4.2
 
 This library enables MIDI I/O communications on the Arduino serial ports.
 The purpose of this library is not to make a big synthetizer out of an Arduino board, the application remains yours. However, it will help you interfacing it with other MIDI devices.

 ### Using MIDI.begin
 
 In the `setup()` function of the Arduino, you must call the `MIDI.begin()` method. If you don't give any argument to this method, the input channel for MIDI in will be set to 1 (channels are going from 1 to 16, plus `MIDI_CHANNEL_OMNI to listen to all channels at the same time).
