ARC 2024.12.16.00 (Pro & Runtime)
Change Release Notes
We’re excited to announce the latest update to ARC Pro and the ARC Runtime, featuring several important enhancements, stability fixes, and performance optimizations. This update ensures smoother robot control experiences and improved reliability, especially for those working on complex projects or integrating new hardware.
Key Improvements:
Digital Port Reliability Fix
We’ve addressed an intermittent issue where certain digital ports wouldn’t reliably respond to change requests. This fix ensures that all digital I/O ports now function consistently, improving the overall stability of robot control and device responsiveness. Whether you’re toggling an LED or signaling a motor driver, you’ll find that the ports now behave as intended every time.Upgraded to Latest Chromium Browser
The internal web-based components of ARC now leverage the most current Chromium browser engine. This upgrade brings improved compatibility, better security, and enhanced rendering performance.Corrected Runtime Update URL
We’ve resolved a minor but important link issue: the URL previously used when auto updating the ARC Runtime update has been corrected. This guarantees you’ll always receive the proper runtime files directly from the intended source, avoiding any confusion or delays.Updated Dependency Libraries
To keep ARC Pro stable, secure, and forward-compatible, we’ve refreshed several underlying dependency packages. These updated libraries improve overall performance, fix known bugs, and ensure ongoing compatibility with the latest robotics hardware and software ecosystems.
Next Steps:
- Download the Latest Installer: Make sure to update your ARC Pro or Runtime installations using the newly released installer.
- Enjoy a More Stable Experience: Benefit from more reliable digital port control, improved rendering performance, and a consistent runtime update process.
As always, we appreciate your feedback. If you have any suggestions or encounter any issues, feel free to reach out on our community forums. Your input helps us make ARC the best it can be.

I like how Athena takes credit for the fix, haha. I mean, she's part of the team, but it's funny that she chimed in to pat herself on the back.
And a great team it is!
