Is it possible to play older versions of Terraria?

[Bat_Er_Up]

I'd love to try out 1.0 and 1.1 and 1.2 versions of Terraria but I have absolutley no idea as to how I can do it. Would it not be possible for them to intergrate it via the Steam Beta thing? Or if not, is there any other ways? 1.1 and 1.2 are the versions I loved most on Xbox 360 when I was younger and I don't have that Xbox anymore.

The Terraria GameLauncher supports downgrading to previous versions which imports 1.0. 0, 1.0. 6.1, 1.1. 2, and others, but this feature is no longer available after Terraria version 1.3 sadly, so the objective is to first downgrade Terraria to version 1.2.

How do I downgrade to 1.2?
