The new major release of the Arduino IDE is faster and even more powerful! In addition to a more modern editor and a more responsive interface it features autocompletion, code navigation, and even a live debugger.
Note: this software is still in beta status, which means that it’s almost complete but there might be minor issues. Help us test it and report your feedback in the forum!
