• Fixed: skfem.utils.enforce now works correctly with rows that have no nonzero entries
• Fixed: Slightly relax the condition in MeshTri and MeshTet.element_finder to decide whether a point is on the element (due to possible float error accumulation)
• Fixed: models.elasticity.plane_stress contained incorrect formula
• Fixed: matplotlib.visuals.plot3 now supports MeshQuad1 by splitting it into triangle mesh and using the respective plotting routine.
• Fixed: supermeshing.intersect will now properly restrict the supermesh to the intersection of the two meshes in 1D.
