Change Release Notes

This update focuses on improving the learning experience, refining the coding workflow, and fixing several usability issues across platforms.


Learning Experience

  • Lessons are now displayed directly inside the Blockly workspace instead of opening in a popup. This makes it much easier for students to follow instructions without switching context or memorizing steps.
  • Added support for lesson types in the configuration system. (UI integration coming soon.)

Activities & Interface

  • Increased the size of the preview button in Activities to make it more visible and easier to use.
  • Chromebook users will now see a prompt to maximize the window, helping ensure the best possible layout and experience.

Blockly Improvements

  • Servo selection dropdowns now display friendly names pulled from EZ-Bits or port summaries (e.g., Left Shoulder, Vertical Head, Right Gripper), making projects easier to understand.

Programming Editors

  • Fixed an issue where selecting variables in the Python and JavaScript editors would insert duplicate $ symbols.
  • Disabled automatic text wrapping in both editors to improve readability and maintain proper code formatting.

Connectivity & Platform Behavior

  • On Android, pressing the WiFi Settings button now opens the device’s system WiFi settings directly.
  • Update checks are now limited to Windows only, avoiding unnecessary checks on other platforms.

Fixes & Stability

  • Fixed an issue where global max servo positions were not correctly applied when loading a project.
  • Prevented guest users from saving projects, ensuring proper account usage and data integrity.

Overall, this update makes ARC-Lite more intuitive for students, cleaner for developers, and more consistent across devices.
