Prospective users should be aware that version 1.8.57 does not include a native dark theme, nor does it feature the real-time debugger found in IDE 2.x. Additionally, for the newest Arduino boards (e.g., Giga R1 WiFi), some board definitions may require manual installation in this older IDE. However, for the vast majority of Arduino-compatible hardware, 1.8.57 remains fully functional.

Critics might call the old IDE outdated, pointing to version 2.x's autocompletion, debugger, and modern interface. But that misses the point. The 1.8.x series was never about features. It was about accessibility. Its stability meant that a tutorial written in 2015 still worked unchanged in 2025. For classrooms in developing nations, where internet bandwidth is scarce, that lightweight, offline installer is a lifeline. It runs on a decade-old laptop and still fits on a USB stick passed between students. In that sense, the old Arduino IDE is not obsolete — it is a preserved ecosystem, a time capsule of when open-source hardware began transforming from a niche hobby into a global movement. Prospective users should be aware that version 1
