Logging into game it says newer version of carbonite available, and I'm using beta 4.03011, which is the most current as I ck everyday incase there is a new version. Unless I'm to use the new release non beta version 4.031 you updated today.
Yes, you are to use the non-beta (release) version.
Alpha = basic groundworks, very buggy and might not even work in some circumstances
Beta = nearly completed product, used for catching remaining bugs
Release = finalized product, hopefully bug-free
Another way to tell which version you should use is to go by the highest version number. For example, 4.031 is a higher number than 4.03011.
