> Hi Tracker users,
>
> Tracker 6.0.2 is here and is very
> highly recommended. Important changes and bug fixes are:
>
>
> --You can now open and export videos as zip files
> containing sequential jpg or png images.
> --The CircleFitter
> tool can now calibrate the scale to its radius and
> set the origin to its center.
> --Angular variables
> work correctly in Model Builder
>
> To upgrade, click
> the green "Now available" button on the toolbar and
> choose Upgrade Now. If you don't see the green button
> choose Help|Check For Upgrades.
>
> Once again, you will
> need to use a full installer to upgrade (upgrade installers
> will be available for future versions). Installers
> for Windows and MacOS can be downloaded from both
> the Tracker home page (http://physlets.org/tracker/)
> and ComPADRE (http://www.opensourcephysics.org/items/detail.cfm?ID=7365).
