Hi all,

App Lab 0.3.2 has been released and is available for download at arduino.cc/en/software/#app-lab-section or via the auto update mechanism.

This release brings Windows for arm64 architecture support, a smoother setup experience, smarter update handling, and new AI‑powered features. We’ve also delivered dozens of fixes across the UI, device management, file handling, and connectivity to make App Lab faster, more reliable, and easier to use. Linux packages have been refreshed as well.

This is the last version we will release for 2025: please download and use it and feel free to report issues either in the Forum or on the freshly release GitHub repo arduino/arduino-app-lab: The cross-platform IDE for developing Arduino Apps, built with Wails.

Enjoy!
