Release Notes: This release updates the GDML schema to include descriptions for parameterized volume types. It adds elliptical cone and the handling of variables in loops to the schema. Obsolete I/O modules and related configuration/build setup have been removed.

Release Notes: The reflection handler has been reimplemented. Extruded solid has been added. Vertex referencing in tessellated solids has been fixed.

Release Notes: The 'loop' machinery was improved so that any volume can be used in a loop. An installation script was added along with support for 'auxiliary' volume information. A 'SimpleExtension' example that shows how to extend GDML with custom elements was added. The obsolete PyGDML package was removed.

Release Notes: A "matrix" element for handling arrays of numbers was added. A "loop" flow-control element was added to solids and structures. Namespaces were added to included files, and the ability to import specific volumes only was added. Support for optical surfaces was added.

Release Notes: New solids have been added: twisted box, twisted trap, twisted trd, and twisted tubs. Support for modularization of the GDML files has been added through tags allowing any GDML file to be included within another.
