- Bug #899: Wrappers/Petsc: the options to reuse matrices in MatMatMult type operations were poorly implemented. - Feature #898: Finite elements given by Spectral should use different quadrature rules (expands what was begun in #896). - Support #897: In Geometry, Local2Global has been rewritten to avoid copy by value. - Bug #896 - bug #335: Fix the shape functions for Spectral finite elements. Ongoing tickets: - Design #887: Files in Geometry have been reorganized deeply; however the work is still in progress concerning the renaming of namespaces following Advanced/Internal convention.
