Improved ControlCommand Handling

  • The Control Command Parameter Manager has been optimized for better performance and stability when handling commands.
  • A new ControlCommand parameterCls has been introduced for improved parameter presentation in the cheatsheet and right-click editor menu.

Performance & Stability Enhancements

Script Editor Gets a Turbo Boost

  • The Edit Column Button in the data grid has undergone a major performance and stability improvement in the underlying renderer. Expect a snappier response when working with scripts.

  • Script Editor Template Master Renderer has been fine-tuned for better performance and reliability, ensuring seamless script editing.

ARC GUI Speed & Stability Boosts

  • The ARC Tab Control, which is used across various UI components, has received a performance upgrade for a more responsive interface.

  • The internal GUI engine renderer has been significantly optimized, with improved memory recovery and multiple stability fixes. This means smoother animations, fewer crashes, and better resource management across the board.

  • Minor tweaks to the internal robot skill GUI template enhance performance and reliability.

Virtual Desktop Manager & Workspace Renderer Revamp

  • If you rely on virtual desktops for organizing your workspace, you're in for a treat! This release introduces significant performance enhancements to the Virtual Desktop Manager and Workspace Renderer, making switching between workspaces blazing fast and buttery smooth.

Audio Wave Editor Upgrade

  • The Audio Wave Editor, found in the Soundboards, has been optimized for better performance and stability. Audio editing and playback now feel more fluid, with reduced latency and increased accuracy.

Fixes & Enhancements

Camera Object Training Fix

  • A pesky dispose error message that occasionally popped up when closing the Camera Object Training window has been fixed.

EZ-B Scan Stability Improvements

  • Scanning for EZ-B controllers is now more reliable, with fewer hiccups when detecting connected devices.

Smoother Script Execution

  • Script Manager is now multithreaded, improving overall execution speed.

  • Global Variable Manager has been fine-tuned for better performance.

  • Scripting File Manager commands now execute faster, making script-heavy projects more efficient.

  • Script Engine Initialization received a minor but meaningful boost, ensuring scripts start without unnecessary delays.

  • Script Command Audio Player is now more stable, preventing unexpected interruptions during playback.


Graphing, Dropdowns & Miscellaneous Tweaks

Internal Graphing Component Optimization

  • The internal graphing engine now leverages unmanaged memory allocation, drastically improving performance and reducing overhead. Expect smoother real-time graphing with minimal CPU load.
  • The ComboBox dropdown has received a minor performance boost and a memory leak fix, preventing slowdowns over extended usage.

ARC Auto-Update Reliability Improvements

  • If the ARC updater fails to download, the installer now properly captures the error instead of leaving you guessing what went wrong.

Internet Connectivity Error Handling

  • The Add Control Icon Button now has improved error handling for when there's no internet connection, preventing unnecessary frustration.

Feature Removals & Deprecations

Twitter & Nest Configuration Removed

  • The Twitter and Nest integrations have been removed from ARC’s framework. If they return in the future, they’ll be available as plugin-based Robot Skills rather than built-in features.

This update is all about speed, stability, and usability. Whether you're scripting, managing your robot's skills, or working with graphical components, ARC now runs more efficiently than ever.

Wow these last few updates had great performance improvements - I can tell. My Rock Pix SBC the turtlebot usually struggles to keep up with camera and lidar better navigator. The CPU usage is still high but the more efficient use of it is noticeable. The camera framerate drops less frames and the better navigator doesn't chug as much. The UI is more responsive than before. Seems like most of ARC has entirely been rewritten for optimizations!

Indeed, great performance updates. The UI is running smoother.

I'm glad you noticed! I'm happy it's not only in my head . The script editor's loading time surprised me; it's more responsive and quicker.

I'm slowly getting used to right-clicking on the workspace for shortcut commands. I still reach for the top ribbon menu by habit, though. It'll take time to relearn that muscle memory.
