ARC 2025.12.03.00 (Pro, Runtime And Free)

This release focuses on improving performance, reliability, and diagnostics. If ARC feels snappier, more stable, and slightly sassier... that was intentional. Enjoy!

New & Improved

Robot Skill Search Box - Now Plays Hide-and-Seek Less

We moved the Add Robot Skill search textbox to the lower part of the window so it’s easier to find and quicker to reach. Your mouse hand will thank us. Your keyboard hand was indifferent.

Exception Logging Windows - With More Drama

New exception dialogs now:

• Display the full error
• Log it to the EZ-B log It’s like ARC now says, "Hey, something broke... but look! I wrote you a little story about it."

Startup Improvements - EZB Manager First in Line

ARC startup was updated so the EZB Manager and folder structure initialize before other systems start doing their thing. Think of it as letting the foundation settle before building the skyscraper.

Diagnostics & Debugging Enhancements

Assembly Resolver Logs - Now With More Detective Work

Additional logging now helps identify when assembly loading fails-especially helpful for robot skills distributed with:

• outdated assemblies
• unversioned assemblies
• incorrectly versioned assemblies In other words, ARC now politely tells vendors: "Your robot skill brought the wrong DLL to the party."

CEF Temp Folder - ARC Has Stopped Trying to Delete the Undeletable

ARC no longer attempts to delete the CEF temp folder on exit because... well, it’s always in use. ARC has accepted this eternal truth and moved on emotionally.

Plugin List Recovery

If the plugin list file is missing, ARC now logs it-and automatically forces a fresh download. No guesswork, no mystery disappearances.

Performance Improvements

Script Editor - Script Tab Rendering Faster

The script tab in the editor popup is now rendered more efficiently. Less waiting, more scripting, fewer existential crises.

Cheat Sheet Tab - Render Boost

The Cheat Sheet tab now renders faster too. Your shortcuts now have shortcuts.

Board Summary Tab - Cleaner & Faster Rendering

Improved rendering for the board summary tab inside the script editor window. Cleaner visuals. Faster loads. Happier devs.

UI & Component Enhancements

Numeric Slider GUI Updated

The numeric slider control now includes better input validation checks. Details: https://synthiam.com/Support/ARC-Overview/how-to-use-number-slider It behaves more consistently and lets fewer shenanigans slip through.

Updated User Control Graph

The UCGraph used in many robot skills has been improved to prevent occasional "object disposed" errors during ARC shutdown. Your logs should now have fewer ghost exceptions haunting them.
