In March 2021, Arduino released the IDE 2.0 beta after a couple of years of work. This beta constituted a major overhaul of the 16-year-old programme. By any measure, Version 2.0 is not a small upgrade. Theia, a cloud and desktop IDE platform, was used to replace the Java environment. Theia is an open source, modular, and cutting-edge platform. The feature set offered in the 2.0 IDE is approximately the same from the user's perspective. Tools like the Serial Monitor and Serial Plotter are still available and have been improved in terms of quality of life.

 


This version, like the previous one, is still an open-source project. The arduino-ide GitHub repository contains the source code and revision history.

Localization into languages other than English is now possible, according to Arduino. Remember that you may contribute to the Arduino IDE translation via Transifex.

Now is the time to upgrade to Arduino IDE 2.0 RC.
