* Added 'visualOnly' flag for re-visualizing checkpointed data.
  Flag can be set via command line, (e.g --visualOnly=1) or

  [ Changeset https://csd.vpac.org/hg/StGermain/rev/ddfbb6475bd6 ]

* Fixed FeVariable_ReadFromFileWithMesh failing issue due to mesh algorithms.
  [ Changeset https://csd.vpac.org/hg/StgFEM/rev/6c905d892ef0 ]

* Added new functionality to XDMF Generator to create the following files:
  XDMF.temporalAll.xmf - load this in paraview (or other) and you can step through time
                         for both swarms and fields.
  XDMF.temporalSwarms.xmf - load this in paraview (or other) and you can step through time for swarms.
  XDMF.temporalFields.xmf - load this in paraview (or other) and you can step through time for fields.
  XDMF.FilesSwarm.xdmf - file list of all timesteps requried for viewing swarms.
  XDMF.FilesField.xdmf - file list of all saved timesteps required for viewing fields.

* Fixed checkpointing failure on multiple procs due to redundant OperatorFeVariable in the
  FieldVariable_Registry.

* Fixed AdvectionCorrection plugin bug.
  [ Changeset https://www.mcc.monash.edu.au/hg/Underworld/rev/74493b98b446 ]

Underworld-1.5
==============

* Testing system has been migrated to CREDO toolkit.
  For more information on CREDO (see `CREDO Documentation
  <https://www.mcc.monash.edu.au/credo-doc/index.html>`_) 

* './scons.py install' will now install to a PREFIX location.

* Recovery Equilibrium of Patches (REP) method is available for stress and strain rate recovery.
  For more information see 'Recovery Methods' in the Cookbook section of the manual.

* 'Scaling' functionality is available.
  Now input parameters and output values can be in user specified SI units.
  See 'Scaling' in the cookbook section of the manual for details.

* New hdf5 initial conditions method available, see Manual section 'HDF5 Initial Condition'.

* Underworld can now run GALE inputfiles (as of GALE 1.4)
  located in Underworld/InputFiles/GaleModels/.

* Stress Boundary Conditions are now available, StressBCs,
  examples Underworld/InputFiles/ex_stress_bcs.xml.

* Compatible with petsc-3.1 and petsc-3.0.

* Significant gLucifer changes:
  * Default image and movie output objects defined: lucDefaultImageOutput and lucDefaultVideoOutput.
  * Experimental vis database export feature added,
    requires SQLite3. Disabled by default.
  * Optimisations for isosurface and scalar field sampling speed,
    Isosurface sampleGlobal=true can be set to disable.
  * Camera: autoZoomTimestep parameter added, is now enabled by default.
  * AutoZoomMargin is no set by margin parameter in Viewport.
  * Default window width/height fits all the viewports at 400x400 pixels each.
  * ColourMaps: allow values assigned to colours by placing a value in parentheses before the colour.
  * CrossSection object added, derived objects can specify position in format x/y/z=min/max/N/N%
  * Capture object created for vis output in plugins.
  * 2d Plot object created for simple line graphs.
  * Tracer 3d rendering improved features, fixed to checkpoint tracer history for vis. 
  * Multisample support added for anti-aliasing.
  * Camera coordX,coordY,coordZ parameters deprecated although coordZ
    can still be used for backward compatibility.
  * Added translateX,Y,Z parameters to camera to move the model around in 3d space.
  * Added rotateX,Y,Z parameters to camera to rotate the model around in 3d space.
  * gLucifer is no longer a plugin, include in the toolboxes "import" list.
  * More off-screen rendering options for X11 added.

Underworld-1.4
==============

  * New configuration step in installation process, './configure.py -h' for help.

  * Changes to the XML user interface, see the file XMLChanges_1.4 for details.

  * Multigrid solver is now available.

  * Superconvergent Patch Recovery (SPR) Method is now available.

  * Significant checkpointing improvements, hdf5 format is now the standard format,
    see manual for details.

  * Testing have been enabled. Currently 443 unit tests + 105 system tests.
    Automatic testing is run periodically on multiple platforms with Shinkou
    system, (see `Shinkou Continuous Integration System
    <https://www.mcc.monash.edu.au/trac/test/build>`_).

  * New constructor/destroy/delete phases for all components and plugins.

  * Toolboxes / Context code tangle has been addressed.

  * Bugfixes and memory cleaning changes also.
