<li>OBJ export has additional choices for setting color attributes.</li>
<li>Support for tiled rendering has been added to VisIt, which allows for rendering images of an arbitrarily large size. Tiled rendering is always enabled with a default tile width and height of 2048. The image tile size can be set to a maximum image tile width and height of 8192.</li>
<li>When trying to export a built-in color table, a more helpful error message is displayed explaining how to properly export.</li>
<li>The visit-install scripts now accepts '-f' argument allowing specification of the distribution filename in lieu of using the 'version' and 'platform' positional arguments.</li>

<li>Database plugins now recognize and automatically define aggregate expressions (e.g. vector, tensor) for a group of similarly named scalar components (e.g. velX, velY, velZ ==> vector(vel)).</li>
<li>Updated Conduit to 0.9.8.</li>
<li>CGNS reader was enhanced to handle SIDS-style time-varying data.</li>
<li>Support for 10-node tetrahedrons was added to the PVLD reader.</li>
<li>XDMF database plugin was updated to treat multiple top-level grids as separate meshes, resolve variables by the owning grid name, avoid leaking fields between sibling grids, and guard against NULL/out-of-range grids instead of crashing. It also skips unsupported top-level grids cleanly, adds debug messages for ignored/unsupported grid cases, and fixes an XdmfGrid ownership leak in metadata population.</li>

<li>The Connected Components Operator, when used improperly, provides more information to users about how to properly apply it.</li>
<li>Operator Change 2</li>
<li>IndexSelect operator was enhanced to support non-regularized grids. It can now be used in 1D mode on ucd meshes of any cell type and curves. Setting a non-unity stride can be useful, for example, in cutting down clutter in point meshes with millions of points.</li>

<ul>
<li>Enhanced <code>multi_test.C</code> data generator to handle both single and double precision.</li>
<li>CMake usage within VisIt has been modernized. VisIt now installs an export set so that VisIt can be 'imported' by other projects. Only use case tested was building a plugin against an installed VisIt. Documentation related to CMake conventions was updated.</li>
<li>Default file locking for HDF5 when built with <code>build_visit</code> is now set to disabled.</li>
<li>As a precaution against default HDF5 file locking behavior (<code>ON/TRUE</code>), if it is not already set in the environment when VisIt is launched, the <code>HDF5_USE_FILE_LOCKING</code> environment variable is set to <code>FALSE</code> in <code>internallauncher</code>.</li>
