Tracker 5.1.3 now released

Hello Tracker users,
I've released Tracker 5.1.3 and this upgrade is especially important for Mac users using OSX Catalina. The most obvious change is that the upgrade installer is now a dmg file rather than a zip. This version also improves the handling of apple events and streamlines the upgrade process on OSX.
Because of this change from zip to dmg, for this time only, choosing Upgrade Now from the green "Now available" button on the toolbar will take you to the Tracker home page where you can download and run the upgrade installer manually. You may be warned about files from the internet, but you can run the installer if you give the OS express permission. Future upgrades will again be automatic.
To upgrade, click the green "Now available" button on the toolbar and choose Upgrade Now. If you don't see the button choose Help|Check For Upgrades.
Full installers are also available for Windows, Mac and Linux from both the Tracker home page (http://physlets.org/tracker/) and ComPADRE (http://www.opensourcephysics.org/items/detail.cfm?ID=7365).
