ARC 2024.12.17.00 (Pro And Runtime)
Change Release Notes
This update provides key improvements and bug fixes aimed at enhancing the user experience when working with the embedded Chromium browser component within Synthiam ARC. By refining how pop-ups are handled and improving overall performance, this release ensures a smoother and more responsive environment for your robotics projects.
What's New
Chromium Display & Focus Fixes
Fixed Issue with Pop-Up Visibility:
Previously, certain prompts or confirmation dialogs that relied on Chromium’s rendering engine might fail to appear. This update addresses that bug, ensuring that all pop-ups are properly displayed when triggered. As a result, users will no longer miss critical dialog information or have to guess the state of ongoing processes.Focus Restoration After JavaScript Pop-Ups:
There was an issue where, after closing a JavaScript pop-up, the Chromium control could lose focus, preventing direct text input into fields. With this fix, the focus is consistently restored to the appropriate input field, allowing uninterrupted data entry and a more seamless interactive experience.
Performance Enhancements
Improved Chromium Engine Efficiency:
This release includes internal optimizations to the embedded Chromium browser component. The result is a notable reduction in CPU overhead, which helps ensure your system resources are more efficiently utilized. Whether you're running complex robot behaviors, performing image recognition, or managing simultaneous sensor feeds, these optimizations can lead to a more responsive and stable ARC environment.Lower CPU Usage Under Load:
Many users rely on ARC to control robots with multiple video feeds, sensor data streams, and scripting tasks all running simultaneously. The enhanced Chromium performance means that even with multiple browser instances or complex web-based interfaces, ARC’s overall CPU load stays lower. This improvement can contribute to longer battery life on portable devices and improved real-time responsiveness for critical robotics functions.

Seem to be having a lil problem with this new install on my tablet. when shows the ARC Auto Update Window, it gets stuck there. This window just sits there (no download in progress) , first time this has ever happened to me on this tablet.
Turns out, if I restart the whole process, it does start to download, the gets to about 4% then simply crashes the whole download. Now took a third attempt to download. hmmm
