<li>The shadowing and depth cueing options (available in the Rendering window) are no longer greyed out by default. These options are only available with VisIt's scalable rendering mode (software rendering). Previously, users had to enable software rendering to activate these buttons. Now, users can directly activate these buttons, which cause VisIt to go into software rendering automatically.</li>

<li>The Tecplot reader now supports shared variables, in both its ASCII and binary flavors. It also allows use of the strand ID, though it still assumes zones are equivalent to domains.</li>
<li>Tecplot also now supports database options which allow the user to override automatic guessing of coordinate variables.</li>
<li>VisIt's VTK reader now serves up 1D rectilinear grids as curve variables as well as scalar variables, making them plottable using the Curve plot.</li>
<li>A bug was fixed with the SAMRAI reader with setting up ghost data.</li>
<li>XDMF files now report time correct in all cases, including when being used for pathlines.</li>
<li>The Nek5000 reader now supports meshes with moving coordinates over time.</li>
<li>The Silo database reader now properly supports UCD meshes with a mix triangles, quads and arbitrary polygons.</li>
<li>The Image database reader no longer shifts cell centered grid coordinates by -0.5.</li>

<li>Multiple memory leaks with the <i>Streamline</i> plot were remoted.
The <i>Streamline</i> plot is now believed to be leak free.</li>
<li>A memory leak was fixed with the <i>Mesh</i> plot.</li>
<li>The limit on the number of slices for the volume plot's 3D texturing mode was increased to 1000 slices. Previously, the GUI allowed for up to 1000 slices, but the implementation was limited to 500 slices. This meant that changing the number of slices to numbers greater than 500 had no effect.</li>
