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.
+\item Previously, the \texttt{parallel::distributed::ContinuousQuadratureDataTransfer}
+ class, which transfers local quadrature point data onto the
+ children of newly refined cells, did not allow different regions of the
+ triangulation store quadrature data of different lengths. This release lifts
+ this restriction, which enables efficient quadrature data storage and data
+ transfer within a triangulation containing multiple material models, each with
+ their own number of local state variables and history variables.
+ As an example, in a solid mechanics simulation, a hyper-elastic material
+ model can be assigned to a region of the mesh requiring no history variables
+ while another part of the triangulation uses an elasto-plastic constitutive
+ model, requiring the storage of local plasticity data at quadrature points.
+ During each refinement of the mesh, \texttt{ContinuousQuadratureDataTransfer}
+ can be used to transfer and interpolate plasticity data from parent cells to
+ their children, ignoring the cells with hyper-elastic constitutive model.
