Hi all, After a long time of battle testing, we’ve now made the Manifold backend in OpenSCAD the default. This means that all users of the development snapshot will, starting with the next nightly build, experience significantly faster rendering. If you rely on, or want to still use, the CGAL backend, you can enable this in preferences (see attached screenshot) or on the cmd-line using `openscad --backend=cgal`. I fully expect people to discover new bugs, so please ask questions here or on IRC, or open GitHub tickets if something doesn’t feel right. Kind Regards, -Marius

A massive thank you to everyone who has worked on this. It's a wonderful enhancement.
