+Improved: The function GridGenerator::torus() run in 3D (volume mesh) would
+previously only use a single cell to represent the poloidal shape, which leads
+to singular mappings similar to how a circle degenerates when meshed with a
+single cell. The poloidal shape is now represented with 5 cells just like the
+circle. Furthermore, the function GridGenerator::torus() has gained an
+optional argument to control the number of cell layers in the toroidal
+direction. The default manifold set to the torus has also been improved: Now,
+the TorusManifold is applied on the surface, a CylindricalManifold to the
+middle cells in toroidal coordinates, and a TransfiniteInterpolationManifold
+on the cells between the surface and the inner ring. This leads to an
+excellent mesh quality for all supported scenarios.

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
