This is the Link branch FreeCAD, with lots of new features and enhancements. This branch is originally created to develop the App::Link feature for use with my Assembly3 workbench. The feature has since been merged with official FreeCAD, but the branch stayed and became the forefront of what future FreeCAD might become. Its function now is to continuously improve and test the Topological naming problem and its fix. Which I eventually plan to merge back into the FreeCAD main branch.
