No, beta in all the loaders and beta is also in the game, although 0.85 has already been released for a relatively long time.
There are no "full versions" of the game yet.
There are demo versions of the game, designed to showcase the work and identify various bugs. It's something vaguely reminiscent of open beta testing. And the latest version of the game, 0.85, carries a certain Latin letter indicating the fix. A later version of the game with new content will likely be released in December, followed by "letters in the version" indicating further fixes.
