Only the latest released version is supported. Releases can be found on the GitHub Releases Page.

Since this game is a single player game that should not produce any network traffic except for loading all assets necessary to play the game, we do not expect many vulnerabilities at all. But since one can never be too sure about such things, we would kindly ask to report any vulnerabilities by opening a regular issue on the Github issue tracker without disclosing details about the vulnerability. The development team will contact the reporter of any security issues and offer a way of secure communications should the need arise.

(We know that that is a rather unusual attempt at managing security vulnerabilities)
