Version 1.4.2 of AstroGrav has the following new and improved features.
Version 1.4.2 of AstroGrav has greatly reduced flickering of faint objects on model windows. In previous versions of AstroGrav, faint objects would flicker noticeably when rotating the view, rotating the system, or evolving the system. This flickering is now much less noticeable. In addition, the graphics drawing is also slightly faster.
Version 1.4.2 of AstroGrav now allows you to use Julian dates in Solar System simulations. To use this, open one of the Solar System sample simulations, deselect the View / Show Time as Date menu item (or the corresponding tool), and notice how the time displayed on the status bar is the time from Julian date zero, which is noon Universal Time (UT) on Monday, January 1, 4713 BC. Because Julian dates are very often used in Solar System astronomy, this feature is most useful when the time unit is set to days.
New Family: Quick Setup
Version 1.4.2 of AstroGrav includes a correction to a fault with the Quick Setup feature of the Edit / Add Family... command. The previous version of AstroGrav had duplicate options for 2D Equidistant Circles. This has now been corrected so that there is one option for 2D Concentric Circles and one option for 2D Equidistant Circles.
Version 1.4.2 of AstroGrav also has many other minor improvements and bug fixes, including the following.
