The core of Teigha DWG has been split into Kernel and Drawings. Kernal is the file-format independent part.
On the Drawings side, it now supports DWG 2018, digital signatures, and large objects that are bigger than 256MB, associative center marks and center lines, new kinds of associative dimensions, associative surfaces, and .rcp file format for point cloud data.
RCP is the point cloud format used by ODA. It consists of a preview image and data in XML format. DGN now supports read-write and render of terrain model elements, as well as tables (r/w, create, render, and edit), and item types. (Tag and tag sets are deprecated.)
