 Changes in V5.4 and V4.4 Released June 26, 2009

New Features:

 1. The code is released under a GPL V2 license.

 2. The main graphics window can be resized.

 3. With the exception of the maximum number of vertices in the
    generated structure, all compile time space allocations have
    been removed and memory allocation is dynamic.

 4. A 2D contour map, as well as 3D meshes, can now be plotted.

 5. Added reading of maps in JANA binary (M81) file format,
    including user-selectable 3d sections of modulated electron
    density files.

 6. Added reading of input files for the FP-LAPW codes ELK and
    EXCITING.

 7. Added computation of cavity volumes and accessible surface area.

 8. Added rendering of interatomic (Bader) surfaces from AIM
    calculations done with WIEN2k.

 9. Increased the maximum number of atom types from 100 to 1000.

10. Automatic creation of VRML and/or POV files can now be turned
    off to save disk space and compute time. This feature is
    particularly important when working with large map files.

11. Frame fixes and enhancements :
   a. Increased default upper limit on frame number to 20 and added
      dynamic increase when that number is exceeded.
   b. Reset the vertex count between frames to allow atoms from
      different frames to occupy the same site
   c. Default pack and clip ranges to sane values in case a flag
      setting is carried over from the previous frame.

12. Removed spurious distance limit of 160pm in best plane calculation
    and improved handling of symmetry-generated atoms. The program
    will now also output angles between planes.

13. Modified the lonepair command to allow creation of cones above
    and below a planar arrangement of atoms. Also, the search radius
    has been uncoupled from the cone height.

14. Added support for space group symbols Aem2, Aea2, Cmce, Cmme,
    Ccce and for the non-standard B-centered settings used by the
    WIEN2k code.

Major Bugs Fixed:

 1. Only apply ellipsoid cutout correction to the bond endpoints
    when the atom in question is actually an ellipsoid, not one
    that got converted to a sphere.

 2. Improved bond truncation near ellipsoids with modulated ADPs

 3. Fixed reading of constrained Uij values from SHELX input.

 4. Removing all spheres from a single frame cleared the entire
    sphere list.

 5. Changed DISCUS input to recognize abbreviations of the "atoms"
    keyword.

 6. Images saved as Postscript could be distorted by the screen ratio.

 7. Fixed problem with calculation of volumes and distortion
    parameters for polyhedra with more than 4 corners.

 8. Fixed several problems with CIF import.

 9. Fixed program so that correct data result when "Cell 16" is
    used for cubic systems.

10. Fixed import of WIEN2k structure and electron density files
    for hexagonal structures (missing transformation from
    rhombohedral setting)

11. Fixed rendering of thermal ellipsoids for hexagonal space groups.
