New version of Circuit Tools (Windows)

5 May 2022

We have released version 2.9.74 of our Circuit Tools Software. This version offers new features and bug fixes, as noted on the Circuit Tools Update, and addresses some issues and suggestions raised in customer feedback following the release of the V2.9.66 BETA.

Version 2.9.74 includes the ability to generate an Ideal Lap video, and also marks the shift to VLC for handling the integrated video (since the previous 2.8.20 release), enabling 60 fps video playback.

We have also uploaded a series of video tutorials for Circuit Tools.
