 Version 4.3.1 (development)
 ===========================
-- Added support for hr-adaptivity using TMOP-based error estimator.
-
-- Adding lowest order Nedelec and Raviart-Thomas basis functions on wedge
-  shaped elements.
-
-- Added initial support for meshes with pyramidal elements, including several
-  pyramidal meshes in the data/ directory and support for the lowest order H1,
-  Nedelec, Raviart-Thomas, and L2 basis functions on pyramids.
-
-- Updated the hypre interface according to changes in hypre-2.22.1. The ADS
-  solver is now fully working on GPUs.
-
-- Tetrahedral meshes no longer need to be reordered to support high order
-  Nedelec basis functions. This will allow future support for Nedelec basis
-  functions on wedges and pyramids which are not amenable to reordering. The
-  ReorientTetMesh method of the Mesh and ParMesh classes has been deprecated.

-/** The DofTransformation class is an abstract base class for a family of
-    transformations that map local degrees of freedom (DoFs), contained within
-    individual elements, to global degrees of freedom, stored within
-    GridFunction objects. These transformations are necessary to ensure that
-    basis functions in neighboring elements align correctly. Closely related but
-    complementary transformations are required for the entries stored in
-    LinearForm and BilinearForm objects. The DofTransformation class is designed
-    to apply the action of both of these types of DoF transformations.
-
-    Let the "primal transformation" be given by the operator T. This means that
-    given a local element vector v the data that must be placed into a
-    GridFunction object is v_t = T * v.
-
-    We also need the inverse of the primal transformation T^{-1} so that we can
-    recover the local element vector from data read out of a GridFunction
-    e.g. v = T^{-1} * v_t.
-
-    We need to preserve the action of our linear forms applied to primal
-    vectors. In other words, if f is the local vector computed by a linear
-    form then f * v = f_t * v_t (where "*" represents an inner product of
-    vectors). This requires that f_t = T^{-T} * f i.e. the "dual transform" is
-    given by the transpose of the inverse of the primal transformation.
-
-    For bilinear forms we require that v^T * A * v = v_t^T * A_t * v_t. This
-    implies that A_t = T^{-T} * A * T^{-1}. This can be accomplished by
-    performing dual transformations of the rows and columns of the matrix A.
-
-    For discrete linear operators the range must be modified with the primal
-    transformation rather than the dual transformation because the result is a
-    primal vector rather than a dual vector. This leads to the transformation
-    D_t = T * D * T^{-1}. This can be accomplished by using a primal
-    transformation on the columns of D and a dual transformation on its rows.
