I noticed that the download folder contains both V1.8.1 as well as V2.2.2 (Beta). I'm curious what is the difference between the regular version and the beta version which is further along. My thought process is if v2.2.2 is further ahead than v1.8.1 that I should just play the v2.2.2. Is there any reason as to why someone should stick with the lesser version. What does being beta mean in this context I guess is what I'm asking?
