The stable version is the main version of the game, which has been thoroughly tested and fixed for bugs. This version supports all previously created saves in any other stable versions of the game.

The beta version is intended for users interested in testing new versions of the game. It may contain various bugs. Before the release of the stable version with the same number, the beta version contained the largest amount of new content. However, saves made in a certain beta version are not supported in any other versions.
