+Changelog
+*********
+
+v0.4.0
+======
+
+API additions
+-------------
+
+*   Added "AllocateQtensor", "AllocateQscalar", "AllocateDofval", "AllocateNodevec", "AllocateElemvec"
+
+API changes
+-----------
+
+*   Removing Paraview interface: replaced by external libraries "XDMFWrite_HighFive" and "XDMFWrite_h5py"
+
+*   Element*: "dV" now only returns raw data, the "asTensor" member function (and free function) can be used to convert the 'qscalar' to a 'qtensor'
+
+*   Separating sparse solver in separate class to offer more flexibility in the future
+
+*   Adding "dot" to "Matrix"
+
+Other updates
+-------------
+
+*   Applying clang-format to source, python API, tests, and examples.
+
+*   Adding test GMatElastoPlasticQPot
+
+*   Adding test based on hybrid material definitions
+
+*   Formatting update: renaming all return variables "out" to "ret"
+
+ *  Correction zero allocation to allows for dofval.size() > nodevec.size()
+
+*   Formatting update xt::amax and xt::sum
+
+*   Renaming private function to begin with caps when the function allocates its return data
+
+*   Reducing copies when using Eigen
+
+*   Reducing default size examples
+
+*   Supporting Windows (#87)
+
+*   Removing xtensor_fixed
+
+*   Using xt::has_shape
