| Version | Change log |
| AstroGrav 5.0.1 Oct 30, 2023 | Enhanced table popups to show data in all available units when the 'Alt' key is depressed. Restored the 'Window/Bring All to Front' command. Corrected a fault that prevented popups from working below the horizon when the viewpoint is attached to a location. Various minor bug fixes and improvements. |
| AstroGrav 5.0 Oct 4, 2023 | Added a new and much more accurate evolution algorithm. Improved the ephemeris generator. Extended locations for viewing and ephemerides to the Sun, Moon, and planets. Completely revised and reorganized the sample simulations, adding many new simulations. Various minor bug fixes and improvements. |
| AstroGrav 4.5.3 Aug 24, 2022 | Corrected a serious evolution fault. Improved manually drawn angles on view windows. Added extra information to view window popups, particularly when the 'Alt' key is depressed. Corrected a fault that prevented 'Edit/Split Object...' from working correctly. Various minor bug fixes and improvements. |
| AstroGrav 4.5.2 Jul 15, 2022 | Greatly improved the choice of angular velocity units in the 'Edit/Import Objects...' command. Corrected a fault that caused the saved track size of a view window to be ignored. Added the 'Gravity Assists' and 'Roche Limit' sample simulations. Various minor bug fixes and improvements. |
| AstroGrav 4.5.1 Jun 15, 2022 | Added twelve new sample simulations. Made several minor improvements and bug fixes to the evolution algorithm. Corrected a fault that prevented the opening of simulations that were last saved with some earlier versions of AstroGrav. Various minor bug fixes and improvements. |
| AstroGrav 4.5 May 22, 2022 | Improved the importing of asteroids with the addition of several new facilities, the manual drawing of angles on view windows, the display of information about background stars, the display and redraw speed of tables, and the printing of simulation windows. Various minor bug fixes and improvements. |
| AstroGrav 4.4.3 Dec 6, 2021 | Made several minor improvements to the 'Edit/Import Objects...' and 'Tools/Generate Ephemeris...' commands. Updated the Solar System sample simulations to 01/01/2022. Improved tables to always displays vertical scroll bars, row scrollers, and help buttons. Various minor bug fixes and improvements. |
| AstroGrav 4.4.2 Oct 12, 2021 | Corrected a fault that could occasionally cause bizarre behavior during evolution. Made Earth-based views automatically view from the home location. Switched on planetary aberration in all solar system view windows. Added an 'Append Epochs to Names' option to the 'Edit/Import Objects...' command. |
| AstroGrav 4.4.1 Sep 6, 2021 | Greatly speeded up evolution in cases where most objects are of low mass. Corrected a fault that caused evolution to fail after importing the same asteroid or comet twice. Corrected faults that caused all orbits to disappear after cancelling an object edit. Various minor bug fixes and improvements. |
| AstroGrav 4.4 Aug 6, 2021 | Made major improvements to the evolution algorithm. Added search options to find celestial positions. Simplified the handling of trajectories and histories. Simplified the handling of invisible objects. Added the Hilda category to the asteroid importer. Various minor bug fixes and improvements. |
