This doesn't add anything new to the game but there are now startup scripts in the installation-directory that should make it possible to run TAXINAUT on any platform (e.g. Linux or Mac) with Java >= 17 installed. See for more information:

Running TAXINAUT like this on Linux (instead of using Proton) should give better performance (it does on my Linux laptop). I don't have a Steam Deck so I don't know if it's possible to install Java on there and start TAXINAUT that way; but if that's possible it might also improve performance on the Steam Deck.
Note that this doesn't make Linux or Mac officially supported (but it should run fine).
