Libfredo6 Version 6.3 May 2026

The main feature introduced in LibFredo6 version 6.3a (released in October 2014) is enhanced support for non-ASCII characters in Windows usernames.

One important note: LibFredo6 v6.3 asks for permission to send anonymous crash reports. This is enabled by default. You can disable it in the settings under "Privacy & Updates." These reports only contain stack traces (which tool caused the error) and your SketchUp version—no model data is ever transmitted.

It introduced critical compatibility updates for newer versions of SketchUp (specifically improving stability for SketchUp 2015 and 2016) and refined the Check for Update system, ensuring users didn't have to manually hunt for new versions of their favorite tools.
