Amrvis version 2.5 release notes.

(This version number corresponds to BoxLib release 2.5).

---------------------------------------------------------------------------
-------------------------------------------------------------- New Features

This version can be run in parallel on both shared memory and distributed
  memory architectures.  See the amrvis documentation for more detail.

I/O of plot file data is implemented in parallel (if the machine's file
  system supports it).

I/O of plot file data is demand driven.  The granularity is a single
  quantity of a single FArrayBox within a MultiFab.   Only the grids
  which are required are read.  No flushing is currently done.

Box indicies are shown in the Dataset (similar to ArrayView) and
  are hierarchical.

The currently selected planes for each view are shown in the isometric
  grid view.

For volume rendering, selection between the value model and the
  lighting model is now a runtime option accessible through an option menu.

Translation of the isometric view (grids and the volume rendering) is now
  supported.  Use the left mouse button while pressing the shift key.

For 2D animations, there is a button ("rgb >") which will write an rgb
  file and advance to the next plotfile (for single clicks) and write
  rgb files for multiple plotfiles (for double clicks).  It works like
  the advance forward (">") animation button and will stop animating and
  writing files when the stop ("O") button is clicked.

There is now a separate program for deriving quantities from plotfiles.
  The program is named AmrDerive (see its documentation).

There is also a separate program for converting old plot files to the
  new plot file format.  The program is named PlotConvert (see its documentation).


---------------------------------------------------------------------------
------------------------------------------------------------- Major Changes

Plot files now have a new directory based format to facilitate both parallel
  I/O and demand driven I/O.

Old plot file formats (ex:  cgmf, sf, etc.) are no longer supported.  All
  plot files must be written in the new directory based format.  Use
  PlotConvert to convert old plot files to the new format.

Rotations in the isometric view (3D only) are implemented in a more
  intuitive frame of reference.

The cursor which is shown in the data image area when the user clicks on
  a data value in the dataset window is now a box surrounding the data point.
  This feature is also optimized.

The value model for volume rendering is optimized and has performance
  comparable to the lighting model.


---------------------------------------------------------------------------
------------------------------------------------------------- Minor Changes

The boxes button is now implemented as a toggle button.

The Dataset color button is now implemented as a toggle button.

The ProjectionPicture "No Autodraw/Autodraw" button is now implemented
  as a toggle button.

For postscript output of the palette, numbers are written as postscript
  text instead of bitmaps.

Fab byte ordering is no longer a user settable parameter.  New plot
  files and fabs know their byte ordering.


---------------------------------------------------------------------------
----------------------------- Features not in this version but coming soon.

This version does not support the following plot file types:
  Cartesian grid (-cgmf -cgsf in old amrvis).
  Terrain.
  R Theta.


---------------------------------------------------------------------------
----------------------------------------------------------------- Bug Fixes

Boxes in planar animations (3D) are now shown correctly.

Quantity names with spaces (ex:  X Velocity) are now supported.

Visual support is correctly handled for displays using default visuals
  other than 8 bit Pseudocolor.
