This release now + contains a class \texttt{FEInterfaceValues} that considers the + restriction of the shape functions from \textit{both} sides of a face and + allows evaluating jumps and averages of shape functions along this + face. These are common components of the bilinear forms of + discontinuous Galerkin schemes (as well as schemes for fourth-order + equations, see the discussion of \texttt{step-47} below) and greatly + simplify the implementation of these methods. \end{itemize} % The changelog lists more than 240 other
