Thank you, @Phlogios. You are right, 1.4 does everything needed in all platforms we saw, the game is maturing more and more quite nicely.
The reason I asked about 1.2 is because, maybe sometime in the future, we can look back at some of the older versions, and then go like "oooh, look how far this project has come! It used to be like THIS before!".
You can think of 1.2 etc. like a "photograph" for keeping good memories.
(By the way, on that link for 1.2, the actual downloaded file still seems to be 1.4.)
