Thanks and ciao,

The TNGViewer and TNGPlayer pages on our site now provide links to http://tng3d.com/version_history.html
The latter page contains edited changelogs from the last few commit messages; we will update it with each new TNG 3D release. Sensitive information will obviously be left out.

Thanks and ciao,
Dario

Regarding your questions:

1. We had never released a changelog so far, mostly because we don’t have any system for publishing changelogs yet. We’ll think about adding a method to view changelogs for future revisions — but we can’t promise anything until we clear this issue with management…

2. The first time you install TNGViewer a few default entries are added to the “Open Recent” submenu in the File menu; these entries will automatically download and display the publicly-available TNG 3D demos.
You can also download said demos for local display as zip archives from http://tng3d.com/download.html
On that page you’ll find a comprehensive archive containing all of the TNG 3D demos, as well as single archives per each demo. The files contained in the archives have the .tngz (TNG Archive) extension, and they can be opened directly in TNG 3D, either by opening them from the File menu or by dropping them on the TNGViewer application icon or window.

Thanks again,
Ciao,
Dario
