+/**
+ * @page changes_between_0.3_and_1.0 Changes between version 0.3 and version
+ * 1.0
+ *
+ * <p> This is the list of changes made after the release of Aspect version
+ * 0.3 and before 1.0. All entries are signed with the names of the author.
+ * </p>
+ *
+ * <ol>
+ * <li>New: There is now a cookbook describing the usage of the GPlates plugin
+ * and possible applications. The internal velocity representation in the
+ * plugin was changed to cartesian and a smoothing algorithm was introduced.
+ * <br>
+ * (Rene Gassmoeller, Wolfgang Bangerth, 2014/04/12)
+ *
+ * <li>New: A global parameter ``Maximum time step'' allows the user to select
+ * the largest time step that a simulation can take.  This may be useful for
+ * complicated models or benchmarking.
+ * <br>
+ * (Ian Rose, Wolfgang Bangerth, 2014/04/12)
+ *
+ * <li>Fixed: The simple material model now ignores negative compositional
+ * values that can occur from numerical undershots and even interpolation onto
+ * the FE space. This makes the cookbook/composition-active.prm work again.
+ * <br>
+ * (Timo Heister, 2014/04/08)
+ *
+ * <li>New: New options to remove rotational/translational modes from the
+ * solution.
+ * <br>
+ * (Ian Rose, Timo Heister, 2014/04/07)
+ *
+ * <li>New: A geometry model implementing a full sphere. There is also a
+ * corresponding gravity model where gravity increases linearly as you move
+ * outward.
+ * <br>
+ * (Ian Rose, 2014/04/07)
+ *
+ * <li>New: The box geometry allows you to specify a repetition argument in
+ * each coordinate direction.
+ * <br>
+ * (Timo Heister, 2014/04/07)
+ *
+ * <li>New: On startup, ASPECT now prints out whether it is running in debug
+ * or optimized mode. This is now part of a general status message at the top
+ * of every run.
+ * <br>
+ * (Wolfgang Bangerth, Juliane Dannberg, 2014/04/7)
+ *
+ * <li>Changed: The GPlates plugin for surface velocities always interpreted
+ * the start time of the model and the time increment between individual input
+ * files in seconds. It now honors the 'Use years in output instead of
+ * seconds' flag in the input file.
+ * <br>
+ * (Wolfgang Bangerth, Rene Gassmoeller, 2014/04/01)
+ *
+ * <li>New: CMake now passes down a preprocessor defined string constant
+ * called <code>ASPECT_SOURCE_DIR</code> that is set to the (top level)
+ * directory in which the ASPECT sources are located. This can be used by
+ * plugins to locate where data files are (e.g., in the <code>data/</code>
+ * directory of the source tree) independent of where the executable is
+ * finally called.
+ * <br>
+ * (Wolfgang Bangerth, 2014/03/31)
+ *
+ * <li>New: The manual now contains a cookbook section that discussed a model
+ * running in a 3d spherical shell. Movies for this model can be found at
+ * https://www.youtube.com/channel/UCDTTQ068ablZ8k9J31wNk_Q .
+ * <br>
+ * (Wolfgang Bangerth 2014/03/30)
+ *
+ * <li>Changed: The 'radial constant' gravity model had a default of $30
+ * m/s^2$ for the magnitude of the gravity. This value makes no sense. It has
+ * therefore been changed to the value we have at Earth's surface: $9.81
+ * m/s^2$.
+ * <br>
+ * (Wolfgang Bangerth, 2014/03/29)
+ *
+ * <li>Fixed: Correct computation of min/max composition statistics.
+ * <br>
+ * (Timo Heister, 2014/03/26)
+ *
+ * <li>Fixed: Corrected calculation of non-dimensional temperature in the
+ * temperature statistics postprocessor plugin.
+ * <br>
+ * (Eric Heien, 2014/03/24)
+ *
+ * <li>Fixed: Restarting from a previously checkpointed solution did not work
+ * when using the Intel compiler and its standard library. This is now fixed.
+ * <br>
+ * (Wolfgang Bangerth, Jacqueline Austermann 2014/03/21)
+ *
+ * <li>New: There is now a postprocessor that computes a measure of dynamic
+ * topography, based on the vertical component of the stress. There is also a
+ * visualization postprocessor that allows to write this information into the
+ * visualization files to generate graphical representations of the data.
+ * <br>
+ * (Wolfgang Bangerth, Jacqueline Austermann 2014/03/20)
+ *
+ * <li>New: Aspect now installs a file <code>AspectConfig.cmake</code> into
+ * the same directory as the executable that can be used by plugins to set up
+ * compiler flags, include paths, etc, to compile a set of source files into a
+ * shared library that can then be loaded at run time from the input file. See
+ * the manual for more information about this mechanism.
+ * <br>
+ * (Matthias Maier, Wolfgang Bangerth 2014/03/03)
+ *
+ * <li>New: The manual now contains a cookbook section introducing a model
+ * that runs in a two-dimensional annulus.
+ * <br>
+ * (Wolfgang Bangerth 2014/02/17)
+ *
+ * <li>New: When running long simulations, the output generated by the "depth
+ * average" postprocessor can become messy and hard to visualize in the format
+ * previously used because it was, essentially, just a text based table. The
+ * data is now written into a file, named <code>depth_average.ext</code> in
+ * the output directory, in any of the output formats supported by deal.II,
+ * where <code>ext</code> is the matching file name extension for the format.
+ * This allows visualization as a time-depth plot. The format is selected in
+ * the input file, along with a number of other settings.
+ * <br>
+ * (Wolfgang Bangerth 2014/02/16)
+ *
+ * <li>New: The "depth average" postprocessor now takes a run-time parameter
+ * in the "Postprocess/Depth average" section of the input file that specifies
+ * into how many depth slices the domain should be subdivided in computing
+ * depth averages.
+ * <br>
+ * (Wolfgang Bangerth 2014/02/14)
+ *
+ * <li>Fixed: The "depth average" postprocessor did not honor the "Use years
+ * in output instead of seconds" parameter in the input file and instead
+ * always printed time in seconds when generating output. This is now fixed.
+ * <br>
+ * (Wolfgang Bangerth 2014/02/11)
+ *
+ * <li>New: The "Simple setups" section of the manual now has a subsection
+ * detailing the generalization of the "Convection in a box" setup to a three-
+ * dimensional situation. This includes links to the movies already available
+ * http://www.youtube.com/watch?v=_bKqU_P4j48 and
+ * http://www.youtube.com/watch?v=CzCKYyR-cmg .
+ * <br>
+ * (Wolfgang Bangerth 2014/01/29)
+ *
+ * <li>New: The manual has a new subsection at the top of the "Cookbooks"
+ * section providing a bit of an outline of how one sets up situations.
+ * <br>
+ * (Wolfgang Bangerth 2014/01/29)
+ *
+ * <li>New: Linear algebra can be done using PETSc instead of Trilinos. For
+ * this, deal.II needs to be configured with PETSc and the preprocessor define
+ * <code>USE_PETSC</code> needs to be set in the Aspect file
+ * <code>include/aspect/global.h</code> before compiling. This feature is
+ * still experimental.
+ * <br>
+ * (Timo Heister, Ian Rose 2014/01/21)
+ *
+ * <li>Fixed: On systems where one needs to link executables statically (for
+ * example on big clusters), it is not possible to load additional plugins via
+ * external shared libraries. This is now disabled and any attempt to do so
+ * will lead to a run-time error.
+ * <br>
+ * (Rene Gassmoeller, Wolfgang Bangerth 2014/01/10)
+ *
+ * <li>New: There is now a section in the manual that describes how to
+ * reproduce the van Keken et al. benchmark.
+ * <br>
+ * (Cedric Thieulot, Juliane Dannberg, Timo Heister, Wolfgang Bangerth
+ * 2014/01/10)
+ *
+ * <li>Fixed: Using the 'density', 'nonadiabatic temperature', 'thermal
+ * energy' or 'viscosity' mesh refinement criterion for parallel computations
+ * led to meshes that made no sense. This was due to a bug in deal.II, not
+ * Aspect, and has been fixed starting with deal.II 8.1. Using this version of
+ * deal.II now also fixes the problem in Aspect.
+ * <br>
+ * (Wolfgang Bangerth 2013/12/18)
+ *
+ * <li>Fixed: The 'temperature statistics' postprocessor put a column 'Average
+ * nondimensional temperature (K)' into the statistics file that was computed
+ * as the average temperature divided by the maximal temperature at the
+ * boundary. This made no sense if the maximal temperature at the boundary was
+ * zero or if the minimal temperature was nonzero. In fact, it also made no
+ * sense if the temperature at the boundary was not prescribed. This is now
+ * fixed: the column is computed as the ratio of the average temperature
+ * divided by the <i>difference</i> between maximal and minimal temperature,
+ * and it is omitted altogether if the temperature is not prescribed on any
+ * part of the boundary or if the difference between minimal and maximal
+ * prescribed boundary is zero.
+ * <br>
+ * (Wolfgang Bangerth 2013/12/05)
+ *
+ * <li>New: There is now a run time parameter that indices the minimal
+ * refinement level of the mesh.
+ * <br>
+ * (Juliane Dannberg 2013/12/03)
+ *
+ * <li>New: The 'composition' mesh refinement criterion now allows to scale
+ * the various compositional fields differently, through parameters given in
+ * the input file.
+ * <br>
+ * (Juliane Dannberg 2013/12/03)
+ *
+ * <li>New: There are now two new mesh refinement criteria: 'nonadiabatic
+ * temperature' refines based on the nonadiabatic part of the temperature
+ * field; 'viscosity' refines based on the viscosity considered as a spatially
+ * variable field.
+ * <br>
+ * (Juliane Dannberg 2013/12/03)
+ *
+ * <li>Fixed: When using adiabatic initial conditions with a shell geometry
+ * and an opening angle of 90 degrees, the perturbation was not located where
+ * it was supposed to be. This is now fixed.
+ * <br>
+ * (Juliane Dannberg 2013/12/02)
+ *
+ * <li>New: There are now boundary temperature and boundary composition models
+ * that simply use the initial temperature and composition as the values that
+ * should hold at the boundary for all future times.
+ * <br>
+ * (Juliane Dannberg 2013/12/02)
+ *
+ * <li>New: Material models can now include reactions between compositional
+ * species.
+ * <br>
+ * (Juliane Dannberg 2013/12/01)
+ *
+ * <li>Fixed: The shear heating term $2\eta \left(arepsilon(\mathbf u)-
+ * rac 13 (	extrm{div}\; \mathbf u)I
ight):\left(arepsilon(\mathbf u)-
+ * rac 13 (	extrm{div}\; \mathbf u)I
ight)$ was computed wrongly for
+ * compressible models for which the divergence of the velocity field is
+ * nonzero. This is now fixed.
+ * <br>
+ * (Wolfgang Bangerth 2013/11/25)
+ *
+ * <li>Fixed: The composition and temperature statistics postprocessors
+ * incorrectly computed the maximal compositional values and maximal
+ * temperature if this maximum was less than or equal to zero. This is now
+ * fixed.
+ * <br>
+ * (Wolfgang Bangerth 2013/11/25)
+ *
+ * <li>New: One can now select in the input file that the model should include
+ * latent heat. The generation of latent heat then needs to be described in
+ * the material model.
+ * <br>
+ * (Juliane Dannberg 2013/11/24)
+ *
+ * <li>New: It is now possible to prescribe boundary values for compositional
+ * fields in cases where there is inflow through a segment of the boundary.
+ * This is implemented through a set of plugins for boundary values in the
+ * same way as is done for temperature boundary values.
+ * <br>
+ * (Juliane Dannberg 2013/11/24)
+ *
+ * <li>New: There is now a refinement criterion "topography" that makes sure
+ * the mesh is always refined at the surface of the domain.
+ * <br>
+ * (Juliane Dannberg 2013/11/24)
+ *
+ * <li>Fixed: When using compressible models with nonlinear iterations such as
+ * "Stokes", "iterated IMPES" or "iterated Stokes" and prescribed boundary
+ * values, there were numerous bugs that should now be fixed.
+ * <br>
+ * (Wolfgang Bangerth 2013/11/21)
+ *
+ * <li>Changed: When the user selects to terminate by end time, the final time
+ * step is adjusted to hit the final time exactly.
+ * <br>
+ * (Ryan Grove 2013/11/19)
+ *
+ * <li>Fixed: When using compressible models, we fixed up the right hand side
+ * vector in a way so that the mean divergence is zero (even though it is of
+ * course locally nonzero due to the compressibility). This is necessary to
+ * ensure the solvability of the linear system, but it is wrong if the domain
+ * has open boundaries through which fluid can escape or enter. We now only
+ * perform this correction if there are no open boundaries and no boundaries
+ * with a prescribed velocity.
+ * <br>
+ * (Wolfgang Bangerth 2013/11/19)
+ *
+ * <li>New: It is now possible to prescribe the velocity only for certain
+ * components in the 'Prescribed velocity boundary indicators' parameter.
+ * <br>
+ * (Timo Heister 2013/11/08)
+ *
+ * <li>New: the "iterated Stokes" nonlinear solver will now stop iterating if
+ * the residual is smaller than the new "Nonlinear solver tolerance".
+ * <br>
+ * (Timo Heister 2013/11/02)
+ *
+ * <li>New: add a visual postprocessor that outputs the artificial viscosity
+ * parameter for the temperature equation on each cell.
+ * <br>
+ * (Timo Heister 2013/10/28)
+ *
+ * <li>Fixed: Moved particle generation to a class, changed particle
+ * integration and generation to be factory patterned classes. There should be
+ * no effect on the user but this will allow for easier extension of particle
+ * functionality in the future.
+ * <br>
+ * (Eric Heien 2013/10/14)
+ *
+ * <li>New: Aspect now not only generates a <code>solution-NNNNN.visit</code>
+ * file for each time step but also a global <code>solution.visit</code> file
+ * that Visit can use to visualize the entire time dependent solution. (Both
+ * of these work with versions of Visit that support this, including Visit
+ * 2.5.0. Unfortunately, versions of Visit between 2.5.1 and the version
+ * current at the time of writing this, 2.6.3, have a bug that prevents this.)
+ * <br>
+ * (Wolfgang Bangerth 2013/10/08)
+ *
+ * <li>Fixed: Performance of matrix assembly has been improved significantly,
+ * especially in 3d: assembly of the temperature system is up to three times
+ * faster, assembly of the Stokes system up to 50%.
+ * <br>
+ * (Timo Heister, Thomas Geenen, Wolfgang Bangerth 2013/10/08)
+ *
+ * <li>New: HDF5/XDMF will only output mesh data when the mesh changes,
+ * reducing total data output significantly. XDMF serialization is also
+ * properly implemented.
+ * <br>
+ * (Eric Heien, 2013/09/27)
+ *
+ * <li>New: HDF5 output now uses DataOutFilter to remove redundant
+ * vertices/values in output data.
+ * <br>
+ * (Eric Heien, 2013/09/27)
+ *
+ * <li>New: Aspect now supports periodic domains (a recent development version
+ * of deal.II is required).
+ * <br>
+ * (Ian Rose, Timo Heister, 2013/09/11)
+ *
+ * <li>New: The manual now has a new section discussing ways to make
+ * computations go faster.
+ * <br>
+ * (Wolfgang Bangerth, 2013/09/03)
+ *
+ * <li>Fixed: The assembly of the temperature and compositional linear systems
+ * in each time step used an unnecessarily large number of quadrature points.
+ * This is now fixed.
+ * <br>
+ * (Thomas Geenen, 2013/08/30)
+ *
+ * <li>Extended: The ability to compute with tracers has been completely
+ * overhauled. In particular, there is now a cookbook in the manual that
+ * describes how to use them.
+ * <br>
+ * (Wolfgang Bangerth, 2013/08/13)
+ *
+ * <li>Added: ability to terminate simulation after specified number of steps.
+ * This is implemented as one of the terminator modules that can be selected
+ * from the input file.
+ * <br>
+ * (Ted Studley, 2013/07/03)
+ *
+ * <li>Added: new initial conditions for the Box geometry to test different
+ * shaped inclusions.
+ * <br>
+ * (Ted Studley, 2013/06/20)
+ *
+ * <li>Removed: The parameter "Nonlinear iteration" was not used anywhere so
+ * it got removed. You might need to delete this line from your prm files.
+ * <br>
+ * (Timo Heister, 2013/06/20)
+ *
+ * <li>New: Nonlinear solver scheme = 'Stokes only' only solves the Stokes
+ * system and ignores temperature and compositional fields.
+ * <br>
+ * (Timo Heister, 2013/06/20)
+ *
+ * <li>New: If the underlying deal.II version supports this, then VTK or VTU
+ * files now contain information about the time and time step number
+ * corresponding to each file, and this is then displayed when using Visit as
+ * the visualization program.
+ * <br>
+ * (Wolfgang Bangerth, 2013/06/16)
+ *
+ * <li>New: In order to implement extensions, in particular new plugins for
+ * material models, geometries, etc, it used to be necessary to put the new
+ * files into the Aspect source directories and re-compile all of Aspect. This
+ * is now no longer necessary: You can just compile your additional plugins
+ * into a shared library and tell Aspect via the parameter file to load this
+ * shared library at start-up. Details on this process are provided in the
+ * manual in the section "How to write a plugin".
+ * <br>
+ * (Wolfgang Bangerth, 2013/06/16)

- * (Wolfgang Bangerth 2014/01/29)
- *
- * <li>New: The manual has a new subsection at the top of the "Cookbooks"
- * section providing a bit of an outline of how one sets up situations.
- * <br>
- * (Wolfgang Bangerth 2014/01/29)
- *
- * <li>New: Linear algebra can be done using PETSc instead of Trilinos. For
- * this, deal.II needs to be configured with PETSc and the preprocessor define
- * <code>USE_PETSC</code> needs to be set in the Aspect file
- * <code>include/aspect/global.h</code> before compiling. This feature is
- * still experimental.
- * <br>
- * (Timo Heister, Ian Rose 2014/01/21)
- *
- * <li>Fixed: On systems where one needs to link executables statically (for
- * example on big clusters), it is not possible to load additional plugins via
- * external shared libraries. This is now disabled and any attempt to do so
- * will lead to a run-time error.
- * <br>
- * (Rene Gassmoeller, Wolfgang Bangerth 2014/01/10)
- *
- * <li>New: There is now a section in the manual that describes how to
- * reproduce the van Keken et al. benchmark.
- * <br>
- * (Cedric Thieulot, Juliane Dannberg, Timo Heister, Wolfgang Bangerth
- * 2014/01/10)
- *
- * <li>Fixed: Using the 'density', 'nonadiabatic temperature', 'thermal
- * energy' or 'viscosity' mesh refinement criterion for parallel computations
- * led to meshes that made no sense. This was due to a bug in deal.II, not
- * Aspect, and has been fixed starting with deal.II 8.1. Using this version of
- * deal.II now also fixes the problem in Aspect.
- * <br>
- * (Wolfgang Bangerth 2013/12/18)
- *
- * <li>Fixed: The 'temperature statistics' postprocessor put a column 'Average
- * nondimensional temperature (K)' into the statistics file that was computed
- * as the average temperature divided by the maximal temperature at the
- * boundary. This made no sense if the maximal temperature at the boundary was
- * zero or if the minimal temperature was nonzero. In fact, it also made no
- * sense if the temperature at the boundary was not prescribed. This is now
- * fixed: the column is computed as the ratio of the average temperature
- * divided by the <i>difference</i> between maximal and minimal temperature,
- * and it is omitted altogether if the temperature is not prescribed on any
- * part of the boundary or if the difference between minimal and maximal
- * prescribed boundary is zero.
- * <br>
- * (Wolfgang Bangerth 2013/12/05)
- *
- * <li>New: There is now a run time parameter that indices the minimal
- * refinement level of the mesh.
- * <br>
- * (Juliane Dannberg 2013/12/03)
- *
- * <li>New: The 'composition' mesh refinement criterion now allows to scale
- * the various compositional fields differently, through parameters given in
- * the input file.
- * <br>
- * (Juliane Dannberg 2013/12/03)
- *
- * <li>New: There are now two new mesh refinement criteria: 'nonadiabatic
- * temperature' refines based on the nonadiabatic part of the temperature
- * field; 'viscosity' refines based on the viscosity considered as a spatially
- * variable field.
- * <br>
- * (Juliane Dannberg 2013/12/03)
- *
- * <li>Fixed: When using adiabatic initial conditions with a shell geometry
- * and an opening angle of 90 degrees, the perturbation was not located where
- * it was supposed to be. This is now fixed.
- * <br>
- * (Juliane Dannberg 2013/12/02)
- *
- * <li>New: There are now boundary temperature and boundary composition models
- * that simply use the initial temperature and composition as the values that
- * should hold at the boundary for all future times.
- * <br>
- * (Juliane Dannberg 2013/12/02)
- *
- * <li>New: Material models can now include reactions between compositional
- * species.
- * <br>
- * (Juliane Dannberg 2013/12/01)
- *
- * <li>Fixed: The shear heating term $2\eta \left(arepsilon(\mathbf u)-
- * rac 13 (	extrm{div}\; \mathbf u)I
ight):\left(arepsilon(\mathbf u)-
- * rac 13 (	extrm{div}\; \mathbf u)I
ight)$ was computed wrongly for
- * compressible models for which the divergence of the velocity field is
- * nonzero. This is now fixed.
- * <br>
- * (Wolfgang Bangerth 2013/11/25)
- *
- * <li>Fixed: The composition and temperature statistics postprocessors
- * incorrectly computed the maximal compositional values and maximal
- * temperature if this maximum was less than or equal to zero. This is now
- * fixed.
- * <br>
- * (Wolfgang Bangerth 2013/11/25)
- *
- * <li>New: One can now select in the input file that the model should include
- * latent heat. The generation of latent heat then needs to be described in
- * the material model.
- * <br>
- * (Juliane Dannberg 2013/11/24)
- *
- * <li>New: It is now possible to prescribe boundary values for compositional
- * fields in cases where there is inflow through a segment of the boundary.
- * This is implemented through a set of plugins for boundary values in the
- * same way as is done for temperature boundary values.
- * <br>
- * (Juliane Dannberg 2013/11/24)
- *
- * <li>New: There is now a refinement criterion "topography" that makes sure
- * the mesh is always refined at the surface of the domain.
- * <br>
- * (Juliane Dannberg 2013/11/24)
- *
- * <li>Fixed: When using compressible models with nonlinear iterations such as
- * "Stokes", "iterated IMPES" or "iterated Stokes" and prescribed boundary
- * values, there were numerous bugs that should now be fixed.
- * <br>
- * (Wolfgang Bangerth 2013/11/21)
- *
- * <li>Changed: When the user selects to terminate by end time, the final time
- * step is adjusted to hit the final time exactly.
- * <br>
- * (Ryan Grove 2013/11/19)
- *
- * <li>Fixed: When using compressible models, we fixed up the right hand side
- * vector in a way so that the mean divergence is zero (even though it is of
- * course locally nonzero due to the compressibility). This is necessary to
- * ensure the solvability of the linear system, but it is wrong if the domain
- * has open boundaries through which fluid can escape or enter. We now only
- * perform this correction if there are no open boundaries and no boundaries
- * with a prescribed velocity.
- * <br>
- * (Wolfgang Bangerth 2013/11/19)
- *
- * <li>New: It is now possible to prescribe the velocity only for certain
- * components in the 'Prescribed velocity boundary indicators' parameter.
- * <br>
- * (Timo Heister 2013/11/08)
- *
- * <li>New: the "iterated Stokes" nonlinear solver will now stop iterating if
- * the residual is smaller than the new "Nonlinear solver tolerance".
- * <br>
- * (Timo Heister 2013/11/02)
- *
- * <li>New: add a visual postprocessor that outputs the artificial viscosity
- * parameter for the temperature equation on each cell.
- * <br>
- * (Timo Heister 2013/10/28)
- *
- * <li>Fixed: Moved particle generation to a class, changed particle
- * integration and generation to be factory patterned classes. There should be
- * no effect on the user but this will allow for easier extension of particle
- * functionality in the future.
- * <br>
- * (Eric Heien 2013/10/14)
- *
- * <li>New: Aspect now not only generates a <code>solution-NNNNN.visit</code>
- * file for each time step but also a global <code>solution.visit</code> file
- * that Visit can use to visualize the entire time dependent solution. (Both
- * of these work with versions of Visit that support this, including Visit
- * 2.5.0. Unfortunately, versions of Visit between 2.5.1 and the version
- * current at the time of writing this, 2.6.3, have a bug that prevents this.)
- * <br>
- * (Wolfgang Bangerth 2013/10/08)
- *
- * <li>Fixed: Performance of matrix assembly has been improved significantly,
- * especially in 3d: assembly of the temperature system is up to three times
- * faster, assembly of the Stokes system up to 50%.
- * <br>
- * (Timo Heister, Thomas Geenen, Wolfgang Bangerth 2013/10/08)
- *
- * <li>New: HDF5/XDMF will only output mesh data when the mesh changes,
- * reducing total data output significantly. XDMF serialization is also
- * properly implemented.
- * <br>
- * (Eric Heien, 2013/09/27)
- *
- * <li>New: HDF5 output now uses DataOutFilter to remove redundant
- * vertices/values in output data.
- * <br>
- * (Eric Heien, 2013/09/27)
- *
- * <li>New: Aspect now supports periodic domains (a recent development version
- * of deal.II is required).
- * <br>
- * (Ian Rose, Timo Heister, 2013/09/11)
- *
- * <li>New: The manual now has a new section discussing ways to make
- * computations go faster.
- * <br>
- * (Wolfgang Bangerth, 2013/09/03)
- *
- * <li>Fixed: The assembly of the temperature and compositional linear systems
- * in each time step used an unnecessarily large number of quadrature points.
- * This is now fixed.
- * <br>
- * (Thomas Geenen, 2013/08/30)
- *
- * <li>Extended: The ability to compute with tracers has been completely
- * overhauled. In particular, there is now a cookbook in the manual that
- * describes how to use them.
- * <br>
- * (Wolfgang Bangerth, 2013/08/13)
- *
- * <li>Added: ability to terminate simulation after specified number of steps.
- * This is implemented as one of the terminator modules that can be selected
- * from the input file.
- * <br>
- * (Ted Studley, 2013/07/03)
- *
- * <li>Added: new initial conditions for the Box geometry to test different
- * shaped inclusions.
- * <br>
- * (Ted Studley, 2013/06/20)
- *
- * <li>Removed: The parameter "Nonlinear iteration" was not used anywhere so
- * it got removed. You might need to delete this line from your prm files.
- * <br>
- * (Timo Heister, 2013/06/20)
- *
- * <li>New: Nonlinear solver scheme = 'Stokes only' only solves the Stokes
- * system and ignores temperature and compositional fields.
- * <br>
- * (Timo Heister, 2013/06/20)
- *
- * <li>New: If the underlying deal.II version supports this, then VTK or VTU
- * files now contain information about the time and time step number
- * corresponding to each file, and this is then displayed when using Visit as
- * the visualization program.
- * <br>
- * (Wolfgang Bangerth, 2013/06/16)
- *
- * <li>New: In order to implement extensions, in particular new plugins for
- * material models, geometries, etc, it used to be necessary to put the new
- * files into the Aspect source directories and re-compile all of Aspect. This
- * is now no longer necessary: You can just compile your additional plugins
- * into a shared library and tell Aspect via the parameter file to load this
- * shared library at start-up. Details on this process are provided in the
- * manual in the section "How to write a plugin".
- * <br>
