    Release Notes: VisIt has been enhanced with many data analysis options. A new wizard was created for setting up comparison-based expressions, allowing simulations to be compared. The DataBinning operator was added, making it possible to calculate statistics over arbitrary spaces. Data selections were added so that plots can restrict the set of mesh cells in one space and then apply that selection to plots in another space. In addition, multi-resolution support was added, and many of VisIt's readers were improved and fixed.

      Release Notes: The GUI has been ported to Qt4 and streamlined. The most obvious change is that users directly open files now instead of adding them into a selected files list (though that feature still exists via preferences). The Operator menus are now hierarchical and support customization. This version includes a new in-situ simulation instrumentation library, called SimV2, which supports vectors, species, AMR meshes, and much more. VisIt's expression and query mechanisms can now execute user-defined code written in Python.

        Release Notes: This release offers a new, richly featured, parallelized Streamline plot that can integrate across domain boundaries. It offers a new Poincare plot for analysis of magnetic fusion datasets. The ParallelCoordinates plot was optimized, and can now display focus highlights. Many improvements have been made to VisIt's database reader plugins. In addition, dozens of bugs were fixed.

          Release Notes: This release includes several new features and bugfixes in addition to performance enhancements for AMR data. The Volume plot now supports lighting when using ray casting, and the plot is also more efficient when rendering uchar data. Various improvements to annotations have been made. Specifically, plot legends can now be displayed horizontally. The Slice, Threshold, and Tube operators provide new options. The Silo, PDB/Flash, ITAPS, MFIX, PlainText, Tecplot, and SAMRAI readers have been enhanced or had bugs fixed. VisIt can now read data from the Gadget 2 SPH code.

            Release Notes: This release includes many feature enhancements and bugfixes. The Streamline plot has been vastly improved to support creation of streamlines across domain boundaries, parallelism, and better numerics. VisIt's user interface can now be translated into other languages using Qt linguist. This release attempts to use the loopback network interface (127.0.0.1) to avoid socket issues. It can use the IceT rendering library on clusters. Many file format readers have been improved, including Tecplot (support for binary files), XDMF, PlainText, FLASH, and EnSight.

              Release Notes: This release fixes important bugs found in the 1.9.0 major release, including several crashes. In addition, improvements have been made to the XDMF, CGNS, SimV1, Silo, Miranda, and Exodus database reader plugins. Recent changes in support deprecate the visit-help@llnl.gov email list for the better visit-users@email.ornl.gov email list, which provides archival. Finally, a VisIt wiki and user forum are available at www.visitusers.org.

                Release Notes: This version is a patch release that fixes issues that were discovered with the 1.8.0 release. Several crashes on the Windows platform were fixed. Profiles for LLNL hosts were updated to comply with new machine configurations. Problems with reading KullLite and Silo data files were resolved.

                  Release Notes: This release includes a number of bugfixes and new features. It supports setting the background for a visualization to a user-specified image, which can be tiled flat or used as a spherical background that moves with the camera. It has a new annotation that inserts extruded text into a 3D visualization. The query infrastructure has been improved, and new queries were added. The plot list now provides a context menu that offers per-plot controls.

                    Release Notes: This release includes a number of bugfixes and new features. The Spreadsheet plot has improved controls, and can now be created by picking on other plots. VisIt now reads several new file formats, including CCSM, Raw triangle, CCM, Claw, ddcMD, M3D, SAS, and VLI. Protein Databank, H5Part, and ChomboVis readers have also been improved, and support has been added for reading gzip/bzip2 compressed files. Simulations can now display multiple strip charts. Bugs with the Threshold, Index select, Revolve, Transform, and Elevate operators have been fixed. The www.visitusers.org wiki site was also created.

                      Release Notes: This release includes a number of bugfixes and new features. VisIt can be built automatically with the build_visit script on many Linux, Mac OS X, and AIX platforms. The build_visit script downloads relevant VisIt and 3rd party source code, and configures and builds it all using your C++ compiler. This release can tunnel its network connections through SSH, has support for reading several new file formats, and has a new Macros window that allows 1-click access to user-defined Python functions. Support for user settings and file association on the Windows platform has been improved.
