From version 0.5.0 to 0.6.0:

Version 0.6.0 brings another significant upgrade to GRUMMP, which now supports meshing from curved boundary data. Starting from the curved boundary representation, GRUMMP discretizes surfaces by sampling, then generates tetrahedral meshes from the resulting surface triangulations. Any boundary points that are inserted during volume refinement are inserted onto the curved surface, not onto a tesselation of the surface. Geometry is currently input via stereolithography files (see Section 3.3 for more information). As a consequence of how geometry is handled internally, GRUMMP now requires the Argonne version of the Common Geometry Module (version 10.2.2) to build. The configure script automatically fetches and builds this if it's needed.^A.1

Additional changes since version 0.5.0:

• Fixed numerous errors and warnings when compiling with gcc 4.4. This is what we get for making a release with an older compiler.
• Support for reading legacy ASCII VTK files, binary UGrid, and binary VGrid files in 3D; these are auto-detected at read time. This is in addition to GRUMMP's template approach for auto-generating code for reading ASCII mesh files.
• Infrastructure changes to centralize manipulation of the mesh topology database. These changes aren't user-visible: the same things happen at almost exactly the same speed. But with this change to better encapsulate mesh topology changes, we expect to be able to relatively easily add support for edges in the 3D mesh database, so that we can generate curved meshes.
• Various other bug fixes.
