    Release Notes: This release adds very interesting features to facilitate the modeling of heliostat fields, and, thereby, the modeling of solar tower systems, the testing of different atmospheric transmittance models, and the ray casting process, allowing users to select the objects which should be taken into account during that process. It also fixes several minor bugs.

      Release Notes: The scripting capabilities have been increased to the point that any operation and functionality available to the users via the GUI is now also available via scripting. This release also solves a bug that produced the unexpected closing of the program when the user tried to cast rays before creating the concentrating geometry, as well as a bug associated with storing a given Tonatiuh "scene" under very particular and uncommon conditions.

        Release Notes: This new version incorporates the option to specify the transmissivity of the media in which the concentrating system is immersed, an optimized ray generation algorithm that analyzes the concentrating geometry as seen from the ray casting surface and determines the areas of the overall ray casting surface from which to actually cast rays, an improved version of the Buie's Sunshape plug-in, and updated Marble's maps that improve the selection of the plant location and the solar time by the user.

          Release Notes: This is a minor release. It solves a series of minor bugs and several major bug: the inappropriate sizing of the ray casting surface; the erroneous generation of the seven-tuples of the photon map; the undesired ability of the user to associate a tracker to a TShapeKit; the inability of the program to open Tonatiuh files containing TShapKit nodes that do not have an associated a TShape node; and the crash of Tonatiuh when the user aborted the operation of creating a Bezier patches TShape node.

            Release Notes: This is a relatively minor release. With respect to version 1.2.0, this release corrects a few minor bugs and adds a new shape plug-in. The main contribution of this release is that, for the first time, it offers Windows users the possibility of downloading a 64-bit version of the program.

              Release Notes: This is a relatively major release. It changes the way the surface from which primary rays are cast into the concentrating system is defined, and the way in which the intersection of a ray with a surface is stored, thus changing the structure of the photon map's records. Caution: it is incompatible with previous versions of the program.

                Release Notes: This is a minor release. It corrects memory leaks and other minor program bugs. It also incorporates a new tracker plug-in suited to simulate the tracking behavior of Fresnel mirrors, and the the automatic sizing of the input scene aperture, i.e., the surface from which the sun rays are cast towards the concentrating system. The Linux 64-bit version of the program incorporates for the first time the self-updating functionality of the program that was incorporated in the 32-bit version of the program a few releases ago.

                  Release Notes: This minor release corrects some memory leaks and other bugs, and incorporates a large number of code improvements that improve program's speed. Users of the 1.1.3 release can go the the Help menu and click on the “Check for updates” option rather than downloading the installer.

                    Release Notes: This release corrects a bug in the Update Manger, introduces changes in the core of the Tonatiuh program that improve and simplify its structure, and adds two new shape plugins, the trough and the surface of revolution versions of the standard non-imaging Trumpet-like concentrator.

                      Release Notes: This release incorporates an Update Manager, which allows the users to check whether a newer version of the program is available and download it. It adds a new shape plug-in to the list of Tonatiuh standard shape plug-ins. This new shape plug-in, "ShapeTroughCHC", allows the user to create trough-like Compound Hyperbolic Concentrators. Several bugs have been fixed.
