 Even mesh creation packages that generate triangles, for instance Delaunay-Voronoi triangulation codes, can be used because each triangle can then easily be decomposed into three quadrangles by linking the barycenter to the center of each edge; while this approach does not generate quadrangles of optimal quality, it can ease mesh creation in some situations and it has been shown that the spectral-element method can very accurately handle distorted mesh elements.
-With version 7.0, the 2D spectral-element solver accommodates Convolution PML absorbing layers.
+With version 7.0, the 2D spectral-element solver accommodates Convolution PML absorbing layers and well as higher-order time schemes
+(4th order Runge-Kutta and LDDRK4-6).
 Convolution or Auxiliary Differential Equation Perfectly Matched absorbing Layers (C-PML or ADE-PML)
 are described in \cite{KoMa07,MaKoEz08,MaKoGe08,MaKo09,MaKoGeBr10}.\\
