      Release Notes: Changes include a rewrite of the Relativistic Corrections, Multipole Expansion (useful e.g. for low-Earth artificial satellites), texture support for all the Solar System planets (the textures can be downloaded automatically using the ORSA download tool), a URL with up-to-date GPS sats ephemeris, and the ability to force the planets and moon to the same position and velocity of the JPL ephemeris file.

        Release Notes: Many bugs were fixed, especially in the GUI. The numerical library was improved with some possible optimizations and speed-ups.

          Release Notes: All the known bugs have been fixed. The graphical user interface has been improved, in particular the 3D OpenGL viewer, with texture support and better rendering of orbits. This release also improves the stability and numerical algorithms, and changes the internal time representation. Import of artificial satellites, and export of numerical integration to an ASCII file is available. There are also improved object editing/generation tools, with the ability to use the orbital covariance matrix for virtual objects generation.

            Release Notes: A new interaction containing Relativistic corrections to the Newton interaction has been added. Minor bugs were fixed.

              Release Notes: This release adds support for Mac OS X and Windows, as well as high performance computing via MPI. The overall stability and the debugging system have been greatly improved. A close approach tool has been added, and perspective projection has been implemented to the OpenGL scene, as well as an Earth map, XY-grid and Z bars, full screen, and orbit cache. A tree-code interaction algorithm has been added, and minor bugs have been fixed.

                Release Notes: This release adds the automatic orbit reference body selection option in OpenGL scenes, as well as wireframe rendering of Solar System planets, enhanced orbit rendering, and improved PostScript output. Four new MPC files are supported, and the date labels for 2D plotting widgets have been improved. Many minor bugs have been fixed.

                  Release Notes: This release integrates the download and import of many asteroid/comet catalogs from MPC, JPL, Lowell, AstDyS, and NEODyS. There is initial support for comets, initial PostScript output support for OpenGL scenes, improved stability and reliability, and many minor bugfixes.

                      Release Notes: Fixes for all known bugs, and improved overall stability. Since this version, ORSA can be considered beta quality software.
