 * Draft_CubicBezCurve_example.png
 * New Draft CubicBezCurve tool, to create 3rd degree Bezier curves in a way similar to Inkscape.

 * Draft_Arc_3Points_example.png
 * New Draft Arc 3Points tool, to create circular arcs by specifying three points through which the arc passes. Originally developed in the BIM Workbench and then migrated to Draft.

 * Draft_layers.png
 * New Draft Layer tool that replaces the seldom used Draft VisGroup, providing a true layer system as it exists in other CAD systems. Draft Layer supports adding objects by drag-and-drop, controls object visibility and, optionally, object color.

 * Draft-TechDraw_integration.png
 * Substantial reworking of Draft SVG routines to improve inclusion of 2D projections in TechDraw pages. This benefits tools like Draft Shape2DView and Arch SectionPlane, when used with TechDraw NewDraft and TechDraw NewArch.

 * Draft_Fillet_example.png
 * New Draft Fillet tool that creates a fillet (rounded corner) or a chamfer (straight line) between two simple Draft Lines.

 * Draft_LinkArray_example.png
 * The introduction of the App::Link object made it possible to create arrays which have many exact references to an existing object instead of shape duplicates (simple copies). This results in more memory efficient arrays. This is possible with the new Draft LinkArray and Draft PathLinkArray tools. Draft LinkArray works in its tree modes, "ortho", "polar", and the new "circular" mode, which was introduced in a separate commit.
