     See [#86](https://ts-gitlab.iup.uni-heidelberg.de/dorie/dorie/issues/86).
 
+* Improved and refurbished `Dorie::H5File`.
+
+    The source file was renamed to `dune/dorie/solver/util_h5file.hh`. The
+    `read_dataset` function is now capable of directly opening dataset paths
+    that contain groups.
 
 ### Deprecated
 * The configuration file key `[parameters.interpolation]` is deprecated due to
     the new scheme for storing parameterization data. DORiE now only supports 
     nearest-neighbor interpolation of parameters and scaling factors.
 
+### Removed
+* The class `H5File::AttributeReader` was completely removed.
