Class numeric doesn't use an indirect pointer to the actual representation any more. This is a speedup. -* mul::expand() was reengineered to not allocate temporary excess memory. +* mul::expand() was reengineered to not allocate excess temporary memory. * Non-integer powers of a symbol are treated as constants by (l)degree() and coeff(). Using these functions on an expression containing such powers used to fail with an internal error message. The side-effect is that collect()
