Gmsh 1.53 released

Version 1.53 of Gmsh, an automatic 3D finite element grid generator, has been announced. "This version contains fairly big changes, so please report any bugs that might have crept in... The three largest modifications are: - big (huge?) improvements in the way Gmsh renders tri/quad meshes and scalar post-processing views, with speedups of more than an order of magnitude on large data sets (and as a side effect, transparency is now fully supported) - new geometrical entity selection with undo capability - full support for second order elements in the mesh module (3-node lines, 6-node triangles, 9-node quads, 10-node tets, 27-node hexas, 18-node prisms and 14-node pyramids)".
